In Hindu cosmology, a manvantara is a major cyclic era of time presided over by a Manu, the archetypal progenitor of humanity, during which the world undergoes creation, sustenance, and partial dissolution.[1] Each manvantara spans 306,720,000 human years (the active period equivalent to 71 mahayugas or great yugas), and there are 14 such eras, separated by sandhya (twilight) periods, that together form a single kalpa, or day of Brahma, lasting 4,320,000,000 human years.[2] The current era, known as the Vaivasvata Manvantara, is the seventh in this sequence and is ruled by Vaivasvata Manu, son of the sun god Vivasvat, who survived a great flood to repopulate the earth.[3]The structure of a manvantara integrates smaller temporal cycles, beginning and ending with transitional periods called sandhyas (twilights) of 1,728,000 human years each, during which dissolution occurs through deluges or cosmic upheavals.[4] Within each manvantara, 71 mahayugas unfold, where a mahayuga comprises four successive yugas—Satya (golden age of 1,728,000 years), Treta (1,296,000 years), Dvapara (864,000 years), and Kali (432,000 years)—reflecting progressive moral and spiritual decline.[5] This framework, detailed in Puranic texts such as the Matsya Purana, underscores the eternal recurrence of cosmic order (ṛta) and the role of divine intervention in renewal.[5]Each manvantara features a distinct set of deities, seven sages (saptarishis), and an Indra as king of the gods, tailored to the era's conditions, with the Manu establishing laws and societal norms akin to a primordiallegislator.[1] In the Vaivasvata Manvantara, the current saptarishis include Atri, Bharadvaja, Gautama, Jamadagni, Kashyapa, Vashistha, and Vishvamitra, guiding humanity through the ongoing Kali Yuga, which began approximately 5,126 years ago.[6] These eras symbolize the interplay of karma, dharma, and divine will, influencing Hindu views on time as non-linear and regenerative rather than finite.[4]
Conceptual Foundations
Definition and Core Principles
In Hindu cosmology, a Manvantara is defined as a cyclic era equivalent to the reign or lifespan of a single Manu, the archetypal progenitor of humanity.[7] This period represents a fundamental division in the temporal framework, during which the world and its inhabitants undergo creation, sustenance, and eventual partial dissolution.[8] The Manu serves as the central governing figure, establishing order and facilitating the renewal of human society following each cycle's conclusion.[9]The core principle of the Manvantara lies in its embodiment of recurring "humanity cycles," where each era introduces a distinct set of moral laws (dharma), guiding sages (rishis), and associated deities tailored to the prevailing cosmic conditions.[7] At the end of a Manvantara, a partial dissolution known as pralaya occurs, dissolving the earthly realm while preserving the seeds for the subsequent cycle's re-creation.[8] This process underscores the impermanence of material existence and the perpetual motion of cosmic renewal.Manvantaras integrate into the broader Hindu conception of cyclic time, or samsara, illustrating the eternal rhythm of manifestation and withdrawal without a linear beginning or end.[9] Through these eras, the universe maintains continuity across generations of humanity, with each Manu acting as a bridge between dissolutions.[7]
Place in Hindu Cosmology
In Hindu cosmology, a Manvantara represents a fundamental subdivision within the larger temporal framework of a Kalpa, which constitutes a single day in the life of Brahma. Each Kalpa encompasses fourteen Manvantaras, sequential eras that collectively span the period of cosmic activity, with each Manvantara serving as a distinct phase of renewal and governance under a progenitor figure. These eras are demarcated by intervening sandhyas, transitional periods characterized by partial dissolution, during which the world undergoes a temporary contraction and reconfiguration before the onset of the subsequent Manvantara.[10]The Kalpa itself embodies the broader cycles of creation (srishti), preservation, and partial dissolution, orchestrated by the divine principles of Brahma, Vishnu, and Shiva. Within this structure, Manvantaras facilitate human-scale renewals, aligning with the preservation phase where societal and cosmic order is maintained and periodically refreshed amid ongoing creation and subtle dissolutions. At the conclusion of a Kalpa, a more extensive naimittika pralaya occurs during Brahma's night, marking a profound partial dissolution that resets the cosmic stage for the next Kalpa, while the intervening sandhyas within the Kalpa provide analogous, smaller-scale resets between Manvantaras.[11][12]Hindu conceptions of time diverge from linear models, portraying it as non-linear and eternally repetitive, with Manvantaras exemplifying this through their role in restoring moral and social order following each pralaya or transitional dissolution. This renewal ensures the reestablishment of dharma, the ethical framework governing human conduct and cosmic harmony, as the world emerges afresh from periods of contraction. Drawing from Puranic narratives, such as those in the Vishnu Purana, Manvantaras thus synchronize with the universe's rhythmic expansion—through acts of creation and proliferation—and contraction—via dissolutions that purge and prepare for regeneration—perpetuating an endless cycle of cosmic vitality.[10][7]
Etymology and Terminology
Linguistic Origins
The term Manvantara is a Sanskrit compound word composed of manu (मनु), referring to a progenitor or thinker, and antara (अन्तर), denoting an interval or period, yielding a literal meaning of "the period or age of a Manu" or "the interval between Manus."[13][14]The root of manu traces to the verbal root man (मन), meaning "to think," which conveys the idea of a thoughtful or intelligent being, often extended to mankind's archetypal ancestor.[15][16] In contrast, antara derives from the preposition antar (अन्तर्), signifying "within," "interior," or "between," thus emphasizing spatial or temporal separation.[17][18]In its earliest attestations within post-Vedic literature, manvantara appears as a conceptual framework for cyclical time periods, with the term first appearing explicitly in texts like the Manusmriti, which defines its duration as 71 yugas.[19] This usage evolves in subsequent compositions, particularly the Puranas, where it gains a more structured philological form tied to cosmological eras.[20]Transliteration variations across Sanskrit manuscripts and scholarly editions include manv-antara, manvamtara, and manwantara, reflecting minor phonetic and orthographic differences in transmission.[20][13]
Scriptural Usage
The term Manvantara appears in Hindu scriptures as a designation for the eras governed by successive progenitors known as Manus, each representing a phase of cosmic renewal and human civilization. In primary Puranic texts, it structures narratives of creation, delineating periods where a Manu oversees the world alongside associated deities, sages, and divine orders. For instance, the Vishnu Purana employs Manvantara to catalog these eras, with Parashara explaining to Maitreya: "The different Manvantaras; those which are past, and those which are to come," followed by descriptions of the first six past Manvantaras under Svāyambhuva, Svārociṣa, Auttami, Tāmasa, Raivata, and Cākṣuṣa Manus, and the current seventh under Vaivasvata.[7]The Bhagavata Purana similarly utilizes Manvantara to outline sequential eras, integrating them into the broader account of divine incarnations and societal frameworks. In its eighth skandha, it details the first four Manvantaras—Svāyambhuva, Svārociṣa, Uttama, and Tāmasa—specifying for each the Manu's progeny, ruling Indra, classes of gods, and seven sages, such as Marīci, Atri, and Vasiṣṭha for the Svāyambhuva era, while noting Vishnu's preservative forms like Yajña and Hari within these periods.[21] This usage frames Manvantara as integral to the Purana's theology of cyclic preservation and ethical order.In the epics, Manvantara connects to genealogical and cosmological histories. The Mahabharata's Shanti Parva references it in discussions of celestial phenomena and epochal shifts, such as the sun's path varying across the Vaivasvata Manvantara—where it illuminates all directions—and the impending Savarnika Manvantara, tying these eras to divine battles and the persistence of dharma.[22] The Ramayana invokes Manvantara in tracing royal lineages, such as Rama's descent from the solar dynasty through Vaivasvata Manu, embedding the term within narratives of heroic ancestry and moral continuity across cosmic ages.The concept of Manvantara evolves across scriptural layers, with allusions to Manu as humanity's forebear appearing in the Brahmanas, such as the Shatapatha Brahmana, which recounts Manu's role in sacrificial renewal and the great flood. The structured cycles of manvantara, however, develop in later Smriti texts like the Manusmriti and the Puranas. The Matsya Purana exemplifies this maturation by sequencing the fourteen Manus, from Svayambhuva to Dakṣasāvarṇi, portraying each Manvantara as a distinct creative interval narrated by the fish incarnation to Manu.
Temporal Structure
Divisions and Subdivisions
A Manvantara is primarily divided into 71 Mahāyuga cycles, each of which consists of four successive Yugas: Satya Yuga, Treta Yuga, Dvāpara Yuga, and Kali Yuga.[20] These Yugas represent progressive stages of moral and spiritual decline within the cosmic order, with the Satya Yuga embodying the pinnacle of virtue and the Kali Yuga marking the nadir.[23] The structure ensures a rhythmic progression of creation, sustenance, and partial dissolution embedded within the broader Manvantara framework, as described in the Purāṇas.[24]Each Manvantara is bookended by transitional phases known as Manvantara-sandhyās, or twilight periods, which occur at the beginning and end. These sandhyās represent intervals of dissolution equivalent in duration to one Satya Yuga, during which a partial cosmic deluge facilitates the renewal process.[20] They serve as bridges between consecutive Manvantaras, allowing for the reconfiguration of the world while preserving the continuity of the larger Kalpa.[25]Unique to each Manvantara are its associated celestial entities, including a specific Indra as the king of the gods, a distinct assembly of Devas (divine beings), and the Saptarishis (seven great sages) who guide humanity.[20] These figures are appointed anew for every era, reflecting the tailored governance and spiritual oversight required for that particular cycle.[26]The renewal at the conclusion of a Manvantara involves a partial pralaya, or dissolution, that submerges the previous human civilization in a deluge, clearing the way for fresh creation under the succeeding Manu.[25] This process, detailed in texts like the Brahmāṇḍa Purāṇa, ensures the periodic revitalization of life forms and societal structures without disrupting the overarching cosmic rhythm.[27]
Duration Calculations
In Hindu cosmology, the duration of a Manvantara is calculated as 306,720,000 human years, corresponding to 71 Mahayugas.[28] This figure derives from the Vishnu Purana, where a Manvantara is defined as the reign of one Manu, encompassing the lifespans of associated deities, sages, and Indras.[28] Each Mahayuga, or Chatur Yuga, lasts 4,320,000 human years, computed as follows:$1 \text{ Mahayuga} = 12,000 \text{ divine years} = 4,320,000 \text{ human years},since one divine year equals 360 human years.[28] Thus, the core formula for a Manvantara is:$71 \times 4,320,000 = 306,720,000 \text{ human years}.In divine terms, this equates to $71 \times 12,000 = 852,000 divine years.[28] The Puranas note an additional period beyond this base calculation, attributed to transitional sandhyas (twilight periods) at the beginning and end of each Manvantara, each lasting 1,728,000 human years—the duration of a Satya Yuga or 0.4 Mahayugas—yielding $2 \times 1,728,000 = 3,456,000 human years.[29] These sandhyas represent partial dissolutions and are incorporated to align the overall cosmic structure, though the primary quoted duration often excludes them for the Manu's active era.[23]The Manvantara integrates into the larger Kalpa (day of Brahma), a period of 4.32 billion human years equivalent to 1,000 Mahayugas.[28] One Kalpa comprises 14 Manvantaras plus 15 sandhyas:$14 \times 71 + 15 \times 0.4 = 994 + 6 = 1,000 \text{ Mahayugas} = 4,320,000,000 \text{ human years}.This structure ensures the total aligns precisely, with the Bhagavata Purana confirming the 71 Mahayuga base per Manvantara.[23]Puranic texts exhibit slight variations in these calculations. For instance, while the Vishnu Purana and Bhagavata Purana standardize 71 Mahayugas, some interpretations approximate a Manvantara as 72 Mahayugas (311,040,000 human years) to simplify arithmetic, though modern scholarly reconciliations favor the precise 71-plus-sandhya model for fidelity to the originals.[23] These differences arise from interpretive rounding in secondary commentaries but do not alter the foundational ratios established in primary scriptures.[23]
The Manus and Their Eras
Role of Manu
In Hindu cosmology, Manu serves as the archetypal first human and progenitor of mankind, emerging as the survivor of the pralaya, or cosmic dissolution, to repopulate the earth following each period of destruction.[30] As the author of the Manusmriti, Manu establishes the foundational laws of dharma, codifying moral and social order to guide human society in alignment with cosmic principles.[30] This role positions him as a partial incarnation or descendant of divine entities, often instructed directly by Vishnu or other supreme forms, ensuring the transmission of sacred knowledge from the divine realm to humanity.[31]The primary duties of Manu encompass presiding over the maintenance of dharma, the eternal order that sustains the universe, by protecting subjects and propagating righteousness through ethical governance and teachings.[31] He advises on societal structures, including the delineation of varnas and ashramas, fostering a balanced civilization rooted in penance, purity, compassion, and truth.[30] Through his progeny—typically sons who become rulers and sages—Manu initiates the renewal of human lineages, thereby restarting the cycle of creation and ensuring the continuity of Vedic wisdom across eras.[31]Manu embodies key attributes such as profound wisdom, unwavering piety, and prophetic foresight, qualities that enable him to navigate the transition from dissolution to renewal.[30] These traits manifest in his role as a bridge between the divine and mortal worlds, where he not only survives cataclysmic events but also safeguards sacred texts and rituals, preventing the loss of spiritual heritage during pralayas.[21] His archetype underscores the interdependence of human agency and cosmic law, symbolizing resilience and the perpetual reestablishment of order in the face of entropy.[21]
List of the Fourteen Manus
In Hindu cosmology, a single Kalpa, or day of Brahma, encompasses fourteen successive Manvantaras, each governed by a unique Manu who serves as the progenitor of humanity during that era. Names and details vary slightly across Puranas such as the Vishnu Purana and Matsya Purana.[7][32] Each Manu's tenure builds upon the preceding one, with progressive cycles of creation, preservation, and dissolution, culminating in escalating moral and societal decline as the Kalpa approaches its end during the Kali Yuga of the final Manvantara.[33]The fourteen Manus are as follows (following the Vishnu Purana where specified):
Svayambhuva Manu: The inaugural Manu, self-born from Brahma, who initiates the cycle of human procreation and establishes the foundational laws of dharma.[7]
Svarocisha Manu: The second Manu, named after his luminous quality, presiding over an era marked by early expansions in divine assemblies.[7]
Uttama Manu: The third, renowned for his supreme virtue, guiding humanity through a period of heightened righteousness.[7]
Tapasa Manu (also Tāmasa in some accounts): The fourth, associated with ascetic rigor, fostering spiritual discipline amid emerging complexities.[7]
Raivata Manu: The fifth, linked to abundance and inheritance, overseeing a phase of prosperous societal growth.[7]
Chakshusha Manu: The sixth, connected to visionary perception, ruling before a prophesied deluge that transitions to the current era.[7]
Vaivasvata Manu: The seventh and current Manu, son of Vivasvat (the sun god), who survived a great flood and repopulates the world in the ongoing Vaivasvata Manvantara.[7]
Savarni Manu: The eighth, son of the sun's shadow (Chāyā), prophesied to lead a balanced era with Bali as Indra.[33]
Daksha-savarni Manu: The ninth, emphasizing ethical governance, under Adbhuta as Indra, with a focus on dutiful progeny. (Note: Matsya Purana calls this Raucya.)[33][7]
Brahma-savarni Manu: The tenth, aligned with creative forces, served by Śānti as Indra, promoting harmonious expansion. (Note: Matsya Purana calls this Bhautya.)[33]
Dharma-savarni Manu: The eleventh, upholding righteousness, with Vṛṣa as Indra, amid increasing cosmic order. (Note: Matsya Purana calls this Merusavarni.)[33]
Rudra-savarni Manu: The twelfth, infused with transformative energy, guided by Ritudhāmā as Indra. (Note: Matsya Purana calls this Ritu.)[33]
Raucya Manu: The thirteenth, oriented toward divine principles, under Divaspati as Indra. (Note: Commonly known as Deva-savarni in other accounts; Matsya Purana calls the 13th Ritadhāman.)[33]
Bhautya Manu: The fourteenth and final, culminating the Kalpa with intensified decline, served by Suchi as Indra. (Note: Commonly known as Indra-savarni in other accounts; Matsya Purana calls this Viswaksena.)[33]
The Current Manvantara
Vaivasvata Manu
Vaivasvata Manu, identified as the son of Vivasvan—the Sun god—and his consort Saranyu, serves as the progenitor of the current human race in Hindu cosmology.[34] As a devoted royal sage known as Śrāddhadeva or Satyavrata, he was performing austerities on the banks of the Kritamala River when a small fish approached him, seeking protection from larger fish.[34]This fish, revealed to be the Matsya avatar of Vishnu, warned Vaivasvata of an impending deluge that would submerge the three worlds in seven days, marking the onset of a pralaya or partial dissolution.[34] Instructed by the avatar, Vaivasvata constructed a large boat and collected all varieties of seeds representing plant life, along with the seven sages (Saptarishis), his family members, and pairs of animals to preserve creation's potential.[34] When the floodwaters rose, the Matsya avatar, now enormous with a single horn, towed the boat—secured by the serpent Vāsuki as a rope—to the peak of Mount Himavat (Himalaya), ensuring their survival through the cataclysm.[34]Following the subsidence of the waters, Vishnu, in his Matsya form, imparted divine knowledge to Vaivasvata and the sages, including the contents of the Matsya Purana, to guide the restoration of order.[34] Vaivasvata then performed severe austerities, invoking his spiritual merit to repopulate the earth with humans and other beings from the preserved seeds, thereby reestablishing societal structures and dharma for the new cycle of existence.[35]The Vaivasvata Manvantara commenced immediately after this flood event, positioning it as the seventh of the fourteen Manus' eras in the current kalpa. It is presently in its 28th mahayuga, within the Kali Yuga phase of that cycle, which began in 3102 BCE following the departure of Krishna.[23] This era defines the contemporary human age, characterized by moral decline as per scriptural descriptions, with the Kali Yuga spanning a total of 432,000 human years and approximately 426,874 years remaining as of 2025 CE.
Associated Deities and Sages
In the Vaivasvata Manvantara, the current era, Indra is identified as Purandara, also known as Shakra, who serves as the king of the Devas and upholds the sovereignty of the heavens.[11][36] Purandara's role emphasizes his function as the protector of cosmic order, wielding the vajra to vanquish demonic forces and ensure the continuity of dharma during this period.The Devas associated with this Manvantara include the Adityas, Vasus, and Rudras, who collectively number thirty-one and are tasked with maintaining the balance of the universe.[11] The twelve Adityas, offspring of Aditi, represent solar principles and oversee natural laws and ethical conduct. The eight Vasus govern elemental forces such as earth, water, and fire, supporting material prosperity and environmental harmony. The eleven Rudras embody aspects of transformation and destruction, aiding in the renewal of creation while preserving overall stability. Together, these groups perform sacrificial rites and intervene in worldly affairs to sustain the moral and physical order under Vaivasvata Manu's reign.The Saptarishis of the Vaivasvata Manvantara are Atri, Bharadvaja, Gautama, Jamadagni, Kashyapa, Vashistha, and Vishvamitra, revered as the seven great sages who guide humanity in dharma and safeguard Vedic knowledge.[37] These sages, invoked in rituals like Sandhyavandana from the Krishna Yajurveda, transmit spiritual wisdom, perform austerities, and advise on righteous governance, ensuring the transmission of sacred texts across generations.[26] Their collective influence promotes ethical living and cosmic piety, with each sage contributing unique insights—such as Kashyapa's role in creation lore and Vasishta's counsel to kings.Across Manvantaras, the Indra, Devas, and Saptarishis are renewed to align with each era's unique cosmic requirements, as described in the Puranas.[11] For instance, the forthcoming eighth Manvantara under Savarni Manu will feature a new set of Saptarishis including Diptimat, Galava, Parashurama, Kripa, Ashwatthama, Vyasa, and Rishyasringa, reflecting the cyclical evolution of divine guidance.[38]
