Two truths doctrine

The Two Truths doctrine is a central philosophical concept in , distinguishing between two interdependent levels of : the conventional truth (samvṛti-satya), which pertains to the apparent, everyday world of dependently arisen phenomena as they are commonly experienced, and the ultimate truth (paramārtha-satya), which discloses the fundamental () of inherent existence in all things. This doctrine, systematized by the second-century philosopher Nāgārjuna, asserts that without relying on conventional truth, the ultimate truth cannot be adequately conveyed, and conversely, the ultimate truth illuminates the empty nature of conventional appearances. It serves as the cornerstone of thought, enabling a between and by affirming the practical validity of worldly experiences while revealing their lack of intrinsic . The doctrine's origins trace back to certain Mahāyāna sūtras, such as the Pitāpūtrasamāgama-sūtra and Samādhirāja-sūtra, where distinctions between mundane and supramundane knowledge are implied, though it was not explicitly formulated until the period and later refined in Mahāyāna traditions. Nāgārjuna, often regarded as the founder of , elaborated the theory in his seminal work, the Mūlamadhyamakakārikā (MMK), particularly in chapter 24, where he states: "The taught by the buddhas is based on two truths: mundane conventions and ultimate." His successor, Candrakīrti (c. 600–650 CE), further clarified it in texts like the Madhyamakāvatāra and its auto-commentary, emphasizing that conventional truth encompasses causally efficacious phenomena that are merely designated in dependence on causes and conditions, while ultimate truth is the non-dual reality free from conceptual proliferation. Philosophically, the Two Truths doctrine integrates the principles of dependent origination () and , positing that all phenomena arise interdependently and thus lack independent essence, as Nāgārjuna articulates: "Since there is no whatsoever that is not dependently originated, therefore there is no whatsoever that is not empty" ( 24:19). This framework critiques substantialist views in earlier Buddhist schools like the , which posited real ontological primitives, by demonstrating through reductio arguments that no entity possesses self-nature (svabhāva). In practice, it supports ethical and soteriological goals: conventional truth validates compassionate action in the world of (), while ultimate truth guides the path to nirvāṇa by dismantling reifying attachments. The doctrine's influence extends across Buddhist traditions, including and later Tibetan and East Asian interpretations, where it adapts to address debates on perception, language, and enlightenment, though remains its primary locus. By reconciling apparent contradictions in reality, it underscores the Buddha's teaching as a skillful means (upāya) tailored to diverse capacities, ultimately pointing to a unified, non-obstructive wisdom.

Fundamentals

Etymology and terminology

The term samvṛti-satya, denoting conventional truth, derives from the root samvṛti, which conveys notions of covering, concealment, or convention, combined with meaning truth; this reflects three primary senses articulated by Candrakīrti: confusion arising from ignorance, codependent arising of phenomena, and worldly consensus or convention. Similarly, paramārtha-satya, referring to ultimate truth, originates from paramārtha, signifying the highest or ultimate object or purpose, paired with satya; Bhāvaviveka interprets it in three ways: as the of phenomena, the object cognized by ultimate wisdom, or cognition concordant with that wisdom. In early Pāli texts of the Theravāda tradition, the equivalents are sammuti-sacca for conventional truth and paramattha-sacca for ultimate truth, where sammuti implies general agreement or convention, and paramattha denotes the highest or ultimate reality. These terms appear in Abhidhamma commentaries, such as the Aṅguttaranikāya Aṭṭhakathā, to distinguish everyday conceptual designations from irreducible ultimate realities like dharmas. Translations into other languages preserve this duality while adapting to linguistic contexts. In , satya is rendered as shí (truth or reality), and the doctrine of two truths as èr dì (two truths or two realities), as seen in Mahāyāna translations from the second century CE onward. In , samvṛti-satya becomes kun rdzob bden pa (all-obscuring truth), etymologically linked to concealment by , while paramārtha-satya is don dam bden pa (truth of the ultimate meaning), denoting the highest, non-deceptive reality accessible through wisdom. Modern English variations typically use "conventional truth" for samvṛti-satya and "ultimate truth" for paramārtha-satya, though alternatives like "relative truth" or "mundane truth" occasionally appear to emphasize the provisional nature of the former. The terminology evolved from early Abhidharma texts, where sources like the Abhidharmakośa (ca. third century ) framed samvṛti-satya as composite, reducible entities (e.g., a pot as a collection of parts) and paramārtha-satya as ultimate, irreducible dharmas such as atoms or moments of consciousness. This distinction served as a hermeneutic tool for analyzing . In Mahāyāna sūtras and treatises from the second century , such as Nāgārjuna's , the terms shifted to emphasize samvṛti-satya as dependently arisen phenomena and paramārtha-satya as their of inherent existence, integrating the doctrine into broader ontological frameworks.

Core concepts

The two truths doctrine in distinguishes between conventional truth (saṃvṛti-satya) and ultimate truth (paramārtha-satya), providing a framework for understanding reality at different levels of analysis. Conventional truth refers to the everyday phenomena that appear interdependent and are shaped by , language, and conceptual designation; for instance, objects like a or a exist validly in this as functional entities reliant on their parts and conditions, without inherent existence. This level of truth governs ordinary experience and ethical conduct, where distinctions such as self and other, cause and effect, hold practical validity for guiding actions toward . In contrast, ultimate truth reveals the empty, non-dual nature of all phenomena, transcending and dualistic perceptions; it points to the lack of intrinsic essence in things, where reality is free from arising, abiding, and ceasing as independently real entities. This truth is apprehended through direct insight, often described as the profound () that underlies all appearances, emphasizing the interdependence of all dharmas without reifying any ultimate substratum. The two truths are inherently interdependent, forming complementary aspects of a single rather than independent or hierarchical realms; neither can be fully comprehended in isolation, as conventional truth provides the provisional basis for approaching the ultimate, while the ultimate illuminates the empty nature of the conventional. This mutual reliance is encapsulated in the doctrine's foundational sūtra formulations, such as the Akṣayamati-nirdeśa Sūtra, which articulates the two truths as essential for practice and non-contradictory teachings on imperishability and . A common misconception portrays the two truths as separate ontological domains—one illusory and the other real—overlooking their unified function in dissolving extremes of and to realize non-dual awareness.

Origins in Early Indian Buddhism

Theravāda tradition

In the Theravāda tradition, the nascent form of the two truths doctrine emerges through distinctions in the Pāli Canon, particularly in suttas that differentiate ethical and meditative understandings of reality from deeper insights into conditioned phenomena. For instance, in the , discourses such as the Alagaddūpama Sutta (MN 22) emphasize the conventional utility of teachings on impermanence, , and not-self for ethical conduct and preliminary meditation, while hinting at their ultimate penetration beyond mere designations to realize the cessation of . These early texts frame the truths in practical contexts, where conventional designations facilitate moral training and , leading toward the unconditioned state of nibbāna without explicit ontological dualism. The Abhidhamma Piṭaka formalizes this distinction into a systematic classification, contrasting paramattha-dhammas—ultimate realities comprising the four irreducible categories of mind (citta), mental factors (cetasika), material phenomena (rūpa), and nibbāna—with paññatti, which are conventional designations or conceptual constructs without inherent existence. Paramattha-dhammas, such as the dhātus (elements) like earth, water, fire, and air, represent objectively existent building blocks of experience that cannot be further analyzed, serving as the foundation for analytical meditation. In contrast, paññatti encompasses everyday labels like "person" or "chariot," which are valid for worldly communication (sammuti-sacca) but dissolve under scrutiny into aggregates and elements (paramattha-sacca). This framework, an innovation of the Abhidhamma, underscores the doctrine's role in deconstructing perceptual illusions without positing metaphysical hierarchies. In vipassanā (insight) , the two truths guide practitioners from recognizing impermanence within conventional phenomena—such as the arising and passing of sensory experiences—to the direct realization of ultimate nibbāna as the unconditioned reality free from all fabrications. This progression involves analyzing objects of through the lens of paramattha-dhammas, dismantling attachments to paññatti-based views, and cultivating toward the transient nature of all conditioned states, ultimately leading to . The fifth-century commentator , in his (Path of Purification), systematizes this distinction for meditative practice, elaborating on how conventional terms (sammuti) like "beings" or "death" must be transcended to discern ultimate realities (paramattha) such as momentary or the elements. Drawing from the Abhidhamma and suttas, integrates the two truths into the stages of purification, emphasizing their soteriological function in insight knowledge without invoking later interpretive layers. For example, he explains that while a "person" exists conventionally for ethical purposes, ultimately only name-and-form (nāma-rūpa) prevails, aiding the meditator's path to arahantship.

Sarvāstivāda and Prajñaptivāda schools

In the school, the two truths doctrine forms a cornerstone of its metaphysics, positing that all dharmas—fundamental constituents of reality—exist across the three times of past, present, and future with their inherent nature (svabhāva) intact. The ultimate truth (paramārthasatya) corresponds to the svabhāva of these dharmas, which are irreducible entities such as atoms or point-instant consciousnesses that persist independently of conceptual elaboration and . In contrast, conventional truth (saṃvṛtisatya) pertains to composite phenomena, like pots or continua of events, which are mere designations (prajñapti) lacking intrinsic existence and ceasing to be cognized upon destruction or analytical breakdown, as exemplified in the Abhidharmakośa (AK 6.4): "The idea of a ends when the is broken; the idea of water ends when, in the mind, one analyzes the water." This framework underscores an ontological realism, where dharmas' eternal presence across time supports causal efficacy and the path to . The Prajñaptivāda school, associated with Harivarman and articulated in the Tattvasiddhi, further elaborates the two truths by emphasizing provisional naming in the conventional realm. Here, conventional truth is defined as prajñapti—designative constructs or imputations that provisionally describe aggregates without inherent reality—while ultimate truth reveals dharmas in their non-designated, intrinsic form, free from such conceptual overlays. The Tattvasiddhi (Chapter 6) integrates this into a broader of truths, linking them to existents (sat) and portraying conventional designations as tools for ethical and soteriological guidance, ultimately subordinate to the direct realization of dharmas' svabhāva. This nominalist inflection highlights the doctrine's role in reconciling scriptural teachings with analytical insight, paralleling Theravāda's emphasis on impermanent analysis without positing eternal dharmas. Scholars debate whether the two truths in these function primarily as epistemological categories—distinguishing modes of (worldly vs. supramundane )—or ontological levels, delineating layers of being from composites to irreducible dharmas. Early texts like the Vibhāṣā treat the truths semantically and epistemologically, focusing on valid of phenomena, whereas later works such as the Saṃyuktābhidharmahṛdaya and Nyāyānusāra equate (truth) with sat (existence), shifting toward an ontological interpretation tied to dharmas' svabhāva across the three times. The Tattvasiddhi bridges this by viewing truths as both cognitive and existential, with prajñapti enabling access to paramārtha without independent ontological status. These formulations profoundly influenced subsequent Abhidharma developments, particularly in Vasubandhu's early Sarvāstivāda-aligned works like the Abhidharmakośabhāṣya, which systematizes the two truths as relative (saṃvṛti) entities ceasing under analysis versus absolute (paramārtha) dharmas enduring it, while critiquing the three-times doctrine from a perspective. This synthesis in the Abhidharmakośa (Chapters VI and VII) extends the doctrine to the path of seeing, where discernment of the across times relies on dharmas' intrinsic nature, paving the way for Vasubandhu's later innovations without fully abandoning the framework.

Development in Indian Mahāyāna Buddhism

Mādhyamaka school

In the Mādhyamaka school, the two truths doctrine serves as a foundational framework for understanding the nature of reality and the Buddha's teachings, emphasizing the deconstructive analysis of phenomena to realize . Nāgārjuna, the school's progenitor in the second century CE, systematically expounds this in chapter 24 of his (), asserting that the relies upon two truths: the conventional (saṃvṛti-satya) and the ultimate (paramārtha-satya). He declares, "The taught by the Buddhas / Relies on the two truths: / The conventional truth / And the ultimate truth" ( 24:8, trans. Garfield 1995). This bifurcation is essential, as Nāgārjuna explains that without relying on the conventional truth, the ultimate truth cannot be conveyed, and without the ultimate truth, nirvāṇa remains unattainable ( 24:10). The conventional truth pertains to phenomena that are dependently originated (), arising through a web of causes and conditions without any inherent or independent existence; this includes everyday entities like a , which exists conventionally as an assemblage of parts but lacks self-nature. In contrast, the ultimate truth is , the of all dharmas from inherent existence, revealing that no phenomenon possesses an intrinsic essence. Nāgārjuna equates dependent origination with , stating, "We analyze that whatever is dependently arisen, / That we explain as " (MMK 24:18), thereby unifying the two truths as aspects of the same reality: conventional appearances are empty, and manifests conventionally. This critiques earlier Buddhist realisms, transforming the two truths into a tool for dialectical negation that undermines attachment to extremes. Subsequent Mādhyamaka developments diverged into the Prasangika and Svātantrika subschools, each interpreting the two truths to refine Nāgārjuna's insights. The Prasangika approach, championed by Candrakīrti in the sixth century CE, treats the ultimate truth as a purely non-affirmative —the mere absence of inherent existence in phenomena—rejecting any provisional positing of realities or independent arguments as concessions to opponents. Instead, it employs reductive consequences (prasaṅga) to expose contradictions in reifying views, leading to a non-conceptual realization beyond linguistic affirmation. The Svātantrika school, founded by Bhāvaviveka in the same era, adopts a more constructive stance, positing a provisional ultimate truth through autonomous syllogisms that affirm as an object of valid cognition while granting limited intrinsic efficacy to conventional phenomena. This allows for incremental epistemic progress toward the ultimate, using logical tools derived from Dignāga to establish positions positively. The two truths doctrine in Mādhyamaka resolves inherent paradoxes by framing the ultimate not as a second, independent truth or ontological layer, but as the transcendence of all extremes—such as , , or —through the of itself. enables the causal efficacy of conventional truths without positing foundational substances, as Nāgārjuna notes that phenomena function precisely because they are empty ( 24:14). This non-dual integration avoids or , guiding practitioners from conventional to ultimate insight, where the two truths are inseparable in the Buddhas' enlightened perspective.

Yogācāra school

The school, also known as Vijñānavāda, reinterprets the two truths doctrine through an idealistic lens, positing that all phenomena arise within consciousness and lack independent external existence. This approach critiques realist views prevalent in earlier Buddhist schools, such as , by arguing that perceived objects are mere representations of the mind rather than autonomous entities. The foundational sūtra for this framework is the Saṃdhinirmocana Sūtra, which distinguishes the two truths to explain the gradual unfolding of the Buddha's teachings: the conventional truth (saṃvṛti-satya) accommodates provisional understandings for those attached to apparent realities, while the ultimate truth (paramārtha-satya) reveals the non-dual, empty nature of consciousness beyond subject-object distinctions. Key figures Asaṅga and his half-brother Vasubandhu systematized this doctrine in works like Vasubandhu's Triṃśikā-vijñaptimātratāsiddhi (Thirty Verses on Consciousness-Only), where the conventional truth corresponds to the parikalpita-svabhāva (imagined nature), consisting of imputed dualistic constructs such as subject and object that are superimposed on experience but ultimately illusory. In contrast, the ultimate truth aligns with the pariniṣpanna-svabhāva (perfected nature), the consummate reality of consciousness purified of all such fabrications, empty of inherent duality and revealing the non-discriminative wisdom of enlightenment. This reframing locates both truths within the mind's operations, emphasizing meditative insight (yoga) to discern their interdependence. Central to Yogācāra's integration of the two truths is the theory of the three natures (trisvabhāva), which provides a phenomenological bridging conventional and ultimate realities. The paratantra-svabhāva (dependent nature) serves as the conventional basis, referring to the causally conditioned flow of (vijñapti) that gives rise to appearances without inherent essence. This dependent arising underpins the imagined constructs of the conventional truth, while its ultimate yields the perfected nature, free from . Unlike the Mādhyamaka school's emphasis on non-affirmative , Yogācāra posits a positive of mind-only (cittamātra), where the three natures elucidate how conventional practices lead to ultimate realization. This idealistic stance critiques external by demonstrating through logical analysis and scriptural that cannot apprehend objects independent of mental factors, as all experience unfolds within the storehouse (ālayavijñāna). argues that assuming external referents leads to and contradicts the impermanence of perceptions, thus affirming the mind as the sole locus for both truths—conventional as the play of dependent arising and ultimate as its intrinsic purity.

Adaptations in East Asian Buddhism

Huayan school

The , a prominent Chinese Mahāyāna Buddhist tradition, uniquely harmonizes the two truths doctrine by emphasizing the interpenetration of ultimate truth (, principle) and conventional truth (shi, phenomena), portraying them as mutually non-obstructive aspects of a singular reality. This approach, developed during the , integrates the conventional world's myriad interdependent events with the unchanging suchness of , resolving apparent dualities into a holistic vision of dependent arising. Foundational to this is the Avataṃsaka Sūtra (Huayan Sūtra), which serves as the school's scriptural basis, depicting the universe as an infinite web of interconnections where phenomena manifest the ultimate without separation. Dushun (557–640 CE), the school's first patriarch, laid the groundwork by interpreting li as the boundless, patterned activity of true nature revealed in nirvāṇa, while shi encompasses the impermanent, conditioned phenomena that pervade and express li, much like waves arising within an ocean. He taught that li and shi mutually pervade, manifest, conceal, and identify with each other, transcending simplistic oppositions between the two truths. Fazang (643–712 CE), the third patriarch, further elaborated this in his teachings, using metaphors such as the golden lion—where the lion's form (shi) embodies its underlying essence (li)—to illustrate their non-dual unity. Central to Fazang's exposition is the metaphor of from the Avataṃsaka Sūtra, envisioning a cosmic net strung with jewels at each intersection, each reflecting all others infinitely, symbolizing how conventional phenomena interrelate to reveal the ultimate principle without obstruction. This harmonization culminates in the fourfold dharmadhātu framework, systematized by later figures like Chengguan but rooted in Dushun and Fazang's ideas, which delineates realms of reality to unify the two truths. The first realm is that of shi, the diverse phenomena of the conventional world; the second is , the singular of and suchness. The third realm addresses the non-obstruction between and shi, where permeates every event and phenomena embody the ultimate seamlessly. The fourth realm extends this to non-obstruction among shi themselves, where all events mutually contain and encompass one another, demonstrating that the conventional fully contains the ultimate, thus resolving duality into an undifferentiated unity of interpenetration. Huayan's subtle integration of the two truths influenced subsequent Chinese Buddhist traditions, particularly (Zen) Buddhism, by providing conceptual underpinnings for sudden and the direct realization of non-duality, though Chan de-emphasizes explicit doctrinal formulations in favor of experiential insight. This interpenetrative vision permeated Chan texts like the Platform Sūtra, where self-nature is seen as generating all phenomena without separation from .

Zen Buddhism

In Zen Buddhism, the two truths doctrine manifests implicitly through experiential practice rather than explicit philosophical exposition, emphasizing the absolute truth of non-duality and the relative truth of conventional phenomena, realized via sudden and . This approach de-emphasizes doctrinal analysis in favor of direct insight into the inseparability of ultimate emptiness and everyday reality, as seen in key and lineages. The Platform Sūtra of the Sixth Patriarch articulates the foundational non-dual realization central to , portraying one mind with two aspects: the absolute purity of self-nature and the relative functioning of phenomena, unified in "without-thinking" (wunian), where arises suddenly without reliance on gradual cultivation. teaches that the mind's true essence is inherently enlightened, transcending dualities like defilement and purity, such that "good knowing is wisdom, and no discursive thought is ," embodying the non-dual of the two truths in immediate . This realization affirms that all phenomena arise from the self-nature, resolving the absolute and relative as aspects of a single, unobstructed mind. In the Linji (Rinzai) tradition, the absolute truth is evoked through the concept of (nothingness or ), as in Zhaozhou's famous response to whether a dog has —"Mu!"—which points beyond conceptual affirmation or negation to the ultimate void of inherent existence. Complementing this, the relative truth appears as "everyday mind" (heijōshin), the ordinary, uncontrived awareness of daily activities, as Linji urges practitioners to "just be ordinary, without trying to be extraordinary," integrating the two truths in spontaneous action without attachment. This dynamic reflects Linji's "true person without rank," who responds freely to phenomena while rooted in absolute freedom from rank or duality. Koan practice in Rinzai Zen serves to resolve the apparent duality between absolute and relative truths, guiding practitioners toward sudden by shattering conventional dualistic thinking. For instance, the "What is the sound of one hand clapping?"—attributed to —forces confrontation with the limits of sensory and logical categories, transcending the relative realm of dual sounds (clapping) to realize the absolute silence of non-dual reality. Through intensive investigation under a teacher's guidance, koans like this cultivate a breakthrough where the two truths interpenetrate, manifesting as embodied wisdom in everyday conduct. Dōgen, founder of the Sōtō school, elaborates this integration in his Shōbōgenzō, particularly in the fascicle "Uji" (Being-Time), where the absolute and relative truths interpenetrate in zazen practice, as each moment of being-time fully encompasses all existence without separation or sequence. Dōgen asserts that "time is being, being is time," rejecting linear causality in favor of a non-dual temporality where past, present, and future dharmas mutually include one another, realizing the two truths through "just sitting" (shikantaza) as the actualization of enlightenment in the present act. This practice-oriented view echoes Huayan influences, such as the li (principle) and shi (phenomena) interpenetration, but grounds it experientially in the body-mind's dropping away during meditation.

Korean Buddhism

In Korean Buddhism, the two truths doctrine finds expression through the essence-function (che-yong) framework, which posits (che) as the ultimate truth of and , and (yong) as the conventional truth of compassionate activity and phenomena, with the two inseparable and interpenetrating. This adaptation, prominent in the Seon () tradition, emphasizes non-duality, where ultimate reality manifests dynamically without separation. The monk Chinul (1158–1210), founder of the , integrated this framework to harmonize Seon meditation with Hwaŏm () doctrine, viewing as the unconditioned samādhi and as prajñā, enabling practitioners to realize sudden followed by gradual cultivation of non-discriminatory wisdom. Chinul's approach synthesizes the two truths by treating and as aspects of one mind, where (ultimate) and (conventional) arise simultaneously, avoiding dualistic extremes. In his Excerpts from the Dharma Collection and Special Practice Record, he describes true mind as encompassing both, stating that "the is samādhi and the is prajñā," underscoring their in . This integration supports a sudden-gradual path, where initial insight into non-duality is deepened through ongoing ethical and meditative efforts. The Hwaŏm school's influence in Korea further adapts the two truths via the four dharmadhātu (realms of reality), a cosmological model illustrating interpenetration: the dharmadhātu of phenomena (conventional), principle (ultimate), mutual non-obstruction, and perfect harmony. Korean Hwaŏm thinkers, building on Ŭisang (625–702), reframed this for Seon contexts, using it to depict how ultimate emptiness encompasses all conventional forms without contradiction, fostering a of sudden awakening and gradual realization. Chinul drew on this to resolve tensions between doctrinal study and meditative insight, promoting a holistic view where the reveal the non-dual nature of reality. In the Sŏn'ga kwigam (Mirror of the Seon Community), composed by Sŏsan Hyujŏng (1520–1604), the essence-function framework guides hwadu (critical phrase) practice toward awakening non-duality, using phrases like Zhaozhou's "mu" (no) to dismantle conceptual barriers between ultimate and conventional truths. This text instructs practitioners to investigate the hwadu until doubt resolves into direct realization of the mind's inherent purity, where essence and function merge beyond words. Hwadu practice, akin to Zen koans, thus embodies the two truths by transcending duality through focused inquiry. In modern Seon Buddhism, the essence-function synthesis continues to balance theoretical understanding with practical application, as seen in movements like Minjung Buddhism, which applies non-dual insights to , viewing conventional suffering as a of ultimate . Contemporary Seon centers emphasize hwadu alongside ethical engagement, preserving Chinul's legacy by integrating the two truths into daily life for personal and communal awakening.

Interpretations in Tibetan Buddhism

Nyingma school

In the Nyingma school, the two truths doctrine finds its most profound expression within the Great Perfection () tradition, where conventional and ultimate truths unite inseparably in the primordial purity (ka dag) and spontaneous presence (lhun grub) of the mind's innate nature. This view posits that all phenomena arise as the dynamic display of a single, non-dual reality, transcending the dualistic frameworks of ordinary perception. Unlike earlier Indian Mahāyāna foundations that emphasize analytical deconstruction, Dzogchen integrates the two truths through direct, non-conceptual recognition of awareness (), revealing their unity as the ground of . Longchenpa (1308–1364), a pivotal Nyingma master, articulates this non-dual integration in his teachings, describing the (gzhi) as the ultimate truth—the primordial basis of reality, an empty yet luminous expanse beyond conceptual elaboration, from which all manifestations emerge. Manifestation (snang ba), corresponding to the conventional truth, refers to the vivid appearances that arise spontaneously from this , like reflections in water: empty of inherent existence yet clearly present, neither diminishing nor substantial. emphasizes their inseparability, stating that "all phenomena that can possibly appear [in the world] arise as the playful display of a single maṇḍala," underscoring how the two truths are epistemically divided—ultimate truth known through non-fallacious, direct , and conventional truth through erroneous, dualistic perception—yet ontologically unified in the 's timeless freedom. Central to this perspective are the Seminal Heart (sNying thig) texts, a key cycle compiled and expanded by in works like the Longchen Nyingtig, which guide practitioners in recognizing as the non-dual awareness that transcends subject-object duality. illuminates the ground's inherent clarity, allowing appearances to self-liberate without suppression or fabrication, thereby dissolving the apparent divide between the two truths into their natural state of equality. These texts portray not as a constructed state but as the ever-present essence, where conventional phenomena are seen as the ornamental display of ultimate , free from the extremes of existence and non-existence. In practice, the two truths are realized through the triad of view, , and conduct, with trekchö (cutting through) and tögal (direct crossing) as primary methods. Trekchö focuses on the view and of primordial purity, cutting through conceptual delusions to rest in the empty essence of mind, directly realizing the ultimate truth as unfabricated where and are inseparable, like and its contents. Tögal extends this into conduct, manifesting the spontaneous presence of conventional truth through visionary displays of and form, integrating both truths in the non-dual fruition of without reliance on gradual analysis. This approach distinguishes itself from by affirming an inherent within the truth, not merely as the absence of extremes but as the innate, self-arisen wisdom () that is primordially pure and cognitively luminous, complementing 's emphasis on with Dzogchen's direct introduction to .

Gelug school

In the school, the two truths doctrine is interpreted through the lens of Prasangika-, emphasizing analytical discernment to realize the inseparability of conventional and truths without reifying either. Tsongkhapa, the founder of the tradition, elaborates this in his Lamrim Chenmo (Great Treatise on the Stages of the Path to ), where he posits that all objects of knowledge serve as the basis for dividing the two truths, each possessing dual natures: the conventional truth as unreal and deceptive appearances established through labeled imputations dependent on conceptual designation, and the truth as the mere absence of inherent existence, a non-implicative that is real and non-deceptive. This framework underscores that conventional phenomena, such as the functioning of eyes or water quenching thirst, are valid as illusion-like imputations preventing , while is free of elaboration to avert . Central to the Gelug rangtong (self-empty) view is the ultimate of all phenomena, including the subject-object duality, where both mind and its objects lack independent nature and arise interdependently through dependent origination. Tsongkhapa argues that this , discerned via rational analysis negating intrinsic existence, reveals the illusion-like quality of reality without implying any positive essence, thus dissolving dualistic perceptions and affirming the extensionally identical yet intensionally distinct natures of the two truths. In this perspective, phenomena are conventionally existent as mere designations but ultimately nonexistent in terms of self-nature, ensuring a balanced path that avoids both and voidness. The Gelug integration of the two truths extends to tantric practices, particularly deity yoga, where visualization of conventional deity forms serves as a method to realize the ultimate emptiness of inherent existence. In the completion stage of highest yoga tantra, practitioners fuse the mind nondually with , transforming conventional appearances into paths that accumulate merit and wisdom, aligning the two truths with the enlightened bodies of a . This approach maintains the doctrinal emphasis on gradual, analytical cultivation, using tantric methods to experientially verify the absence of duality without diverging from Prasangika principles. Gelug scholars, following Tsongkhapa, engage in debates with other Tibetan schools to affirm the two truths on an objective basis—each entity possessing two natures—rejecting subjective divisions that might conflate or incommensurate the truths, as seen in critiques of (e.g., Gorampa) and interpretations emphasizing a non-dual ground. This position upholds the equal actuality of both truths without , ensuring analytical rigor prevents or , and contrasts with 's more immediate non-dual recognition by prioritizing logical discernment.

Parallels in Other Traditions

Jainism

In Jainism, the doctrine of anekāntavāda posits that reality is inherently multifaceted, with no single perspective capturing its entirety, emphasizing partial truths qualified by syāt ("in some sense" or "relatively") that align with conventional understandings of in everyday . This approach underscores the limitations of human perception, where statements about objects or events hold validity only conditionally, mirroring how conventional truths in other traditions acknowledge contextual dependencies without claiming absoluteness. Ultimate truth, in contrast, is realized through kevala jñāna, the state of attained by liberated souls, which encompasses all aspects of reality without distortion by karma or partiality. Complementing anekāntavāda, syādvāda employs a sevenfold predication (saptabhaṅgī) to articulate these perspectives, systematically avoiding dogmatic by predicating qualities conditionally—such as "in some sense, it exists" (syād ), "in some sense, it does not exist" (syād nāsti), and combinations including indescribability (syād avaktavya). This method fosters an insightful recognition of reality's complexity, promoting a balanced view that integrates affirmation, negation, and beyond, akin to discerning layered truths in philosophical . The Tattvārtha Sūtra, a foundational Jain text attributed to Umāsvāti, delineates naya (standpoints) as partial aspects of valid knowledge (pramāṇa), distinguishing conventional or perspectival views—such as substance (dravyārthika) and modal (paryāyārthika)—from the comprehensive truth accessible only through omniscient cognition. These standpoints highlight how ordinary knowledge remains incomplete, urging practitioners toward holistic understanding. Jain epistemology rooted in anekāntavāda and syādvāda embodies non-violence (ahiṃsā) by cultivating epistemic that encourages , as acknowledging multiple valid viewpoints reduces conflict and promotes in interfaith and social interactions. This relativistic framework aligns ethical conduct with , reinforcing Jainism's commitment to through respectful .

Advaita Vedānta

In Advaita Vedānta, the two truths doctrine finds an analogue in the distinction between vyāvahārika satya (conventional or empirical reality) and pāramārthika satya (ultimate or absolute reality), as articulated in Śaṅkara's commentaries on foundational texts such as the Brahma Sūtra and the principal Upaniṣads. Vyāvahārika pertains to the transactional world of everyday experience, governed by māyā and appearing real within the domain of ignorance, while pāramārthika refers to the non-dual , the sole unchanging reality that sublates all appearances upon realization. This bifurcation allows for the practical validity of empirical phenomena without compromising the ultimacy of , mirroring the Buddhist conventional and ultimate truths but rooted in a monistic . Central to this framework is the concept of non-dual (advaita) reality, where the empirical world manifests as a vivarta—an apparent transformation or superimposition—on Brahman, rather than a complete illusion or independent entity. Māyā, as Brahman's inscrutable power, projects this multiplicity without altering Brahman's essential unity, rendering the world "neither real nor unreal" (sad-asat-vilakṣaṇa) in the conventional sphere. Unlike a mere delusion that negates all experience, vivarta affirms the world's relative efficacy for ethical and soteriological purposes, such as pursuing knowledge, while ultimately resolving into the undifferentiated Brahman. In Śaṅkara's independent treatise Upadeśasāhasrī, knowledge () serves as the discriminative tool () that delineates these levels of reality, culminating in mokṣa (liberation). Through direct, intuitive realization (aparokṣa ), informed by scriptural instruction (śravaṇa), reflection (manana), and meditation (nididhyāsana), the seeker discerns the eternal ātman from transient phenomena, dissolving ignorance and affirming identity with . This process, emphasized as the sole path to freedom, integrates the two levels by transcending duality without invalidating provisional truths. Unlike the Buddhist doctrine of anātman (no-self), which denies any enduring essence, Advaita Vedānta, per Śaṅkara, upholds the ātman as self-luminous, eternal consciousness identical with , critiquing anātman as leading to . This affirmation provides a substantive ground for liberation, contrasting with Buddhism's emphasis on the cessation of conditioned factors without an underlying self.

Mīmāṃsā

In the tradition, as articulated in Jaimini's foundational Mīmāṃsā Sūtra (c. 300–200 BCE), is conceived as the ultimate ethical and cosmic order, accessible primarily through Vedic rituals and the authoritative of the scriptures, which guide conventional actions toward transcendent ends like (heaven). This , comprising over 2,500 aphorisms across twelve chapters, posits that knowledge of derives exclusively from Vedic injunctions (codanā), where śabda (verbal testimony) serves as the paramount pramāṇa (means of knowledge), ensuring rituals are performed with precision to align human agency with eternal truths. By emphasizing orthopraxis over metaphysics, bridges the conventional realm of ritual performance with the of , viewing not merely as descriptive but as prescriptive, compelling action that sustains cosmic harmony. Mīmāṃsā distinguishes between two levels of verbal testimony: laukika (worldly or conventional), which encompasses human speech and empirical conventions, and vaidika (scriptural), representing the infallible, eternal authority of the . Laukika śabda is subordinate and fallible, reliant on human reliability and context, whereas vaidika śabda is apauruṣeya (authorless and eternal), intrinsically valid (svataḥ prāmāṇya) and free from error, providing direct insight into super-sensible duties beyond sensory . This duality allows śabda to mediate between everyday conventions—such as norms governing preparation—and the ultimate Vedic truths, which prescribe actions yielding apūrva (unseen potency) for spiritual merit, thereby integrating the mundane into the sacred without contradiction. The tradition divides into two subschools, Bhāṭṭa and Prābhākara, differing on the validity and interpretation of Vedic statements. The Bhāṭṭa school, associated with (c. ), upholds an indirect approach (abhihitānvayavāda), where individual words first convey isolated, uncontextualized meanings (padārthas), and sentence-level validity emerges through secondary implication (lakṣaṇā) to synthesize them into a coherent injunctive force. In contrast, the Prābhākara school, founded by Prabhākara Miśra (c. ), advocates a direct validity (anvitābhidhānavāda), positing that words inherently express interconnected meanings tied to action via their denotative power (śakti), with the sentence's overall validity arising immediately from this relational structure, emphasizing the ' self-evident prescriptive intent. Both subschools affirm the intrinsic validity of vaidika statements, rejecting the need for external validation, though Prābhākaras limit śabda-pramāṇa strictly to apauruṣeya texts, treating human testimony as inferential. Mīmāṃsā critiques Buddhist , which treats linguistic conventions as mere imputations without inherent , by affirming the eternality of words (śabda-tva) and their intrinsic connection to universals (). Drawing on Kumārila Bhaṭṭa's Ślokavārttika, the school argues that Vedic śabda denotes objective, eternal entities rather than illusory constructs, countering the Buddhist view of as depicting a deceptive saṁvṛti (conventional reality) devoid of . This defense upholds the ' apauruṣeya nature, ensuring that śabda conveys true, non-deceptive knowledge of , distinct from Advaita Vedānta's focus on non-dual ontological realization.

Pyrrhonism

In , the ancient Greek skeptical tradition, the distinction between phenomena and non-evident realities in ' Outlines of Pyrrhonism parallels the Buddhist two truths doctrine by emphasizing an epistemological balance that avoids dogmatic assertions about reality. Sextus describes phenomena as the appearances that guide everyday conduct without commitment to their objective truth, while non-evident realities represent the underlying, ultimately unknowable realities that cannot be confidently affirmed or denied. This opposition leads to epochē (), fostering ataraxia (non-dogmatic tranquility) as the goal of inquiry, much like the conventional truth accommodates practical engagement while the ultimate truth eludes absolute grasp. Aenesidemus' ten modes further underscore this relativistic framework, akin to the interdependence highlighted in conventional truth. These modes argue for the relativity of perceptions across differences in animals, humans, senses, circumstances, and relations, demonstrating that no appearance holds absolute validity but depends on contextual factors. By establishing equipollence—equal plausibility of opposing views—the modes induce suspension, mirroring how conventional truths in the two truths doctrine arise interdependently without inherent independence. Scholarly comparisons highlight shared commitments to avoiding epistemological extremes, though Pyrrhonism diverges by lacking an ontological of . Both traditions employ dialectical methods to suspend judgment between , achieving mental without positing a metaphysical void. However, while asserts the of inherent existence as an ultimate insight, Pyrrhonism remains agnostic, focusing solely on the unknowability of non-evident realities without ontological claims. Post-20th-century comparative philosophy has increasingly explored these parallels, influencing of and . Works like Thomas McEvilley's analysis revive interest in 's affinities with , emphasizing their mutual rejection of dogmatic realism. Adrian Kuzminski's examination further positions as a Western analogue to early Buddhist thought, promoting its relevance in contemporary debates on and tranquility.
