Mazu Daoyi
Mazu Daoyi (709–788 CE), also known as Master Ma (Mazu), was a Chinese Chan Buddhist monk of the Tang dynasty renowned for founding the Hongzhou school, which emphasized direct realization of inherent enlightenment through everyday activities.[1][2] Born to the Ma family in Hanzhou, Sichuan province, he received monastic ordination and trained under the meditation master Nanyue Huairang before establishing his teaching center at Gongshui and later Hongzhou monasteries in Jiangxi, where he gathered the largest recorded number of Chan disciples, exceeding 80 dharma heirs including Baizhang Huaihai and Nanquan Puyuan.[3][4] Mazu's doctrinal core, encapsulated in sayings like "ordinary mind is the Way" and "this very mind is Buddha," promoted sudden awakening to one's Buddha-nature without dependence on scriptural study or ritualistic cultivation, employing unconventional methods such as shouts, slaps, and paradoxical encounters to provoke insight among students.[5][1] His Hongzhou lineage rapidly expanded across Tang China, supplanting earlier Chan traditions and laying foundational influences on the mature Chan schools that later transmitted to Japan as Zen, marked by an iconoclastic ethos prioritizing functional spontaneity over doctrinal orthodoxy.[4][2]
