Dayi Daoxin

Dayi Daoxin (580–651) was a foundational figure in Chinese Chan Buddhism, recognized as the fourth Chán Patriarch. His life and teachings were instrumental in shaping the lineage, particularly through his establishment of a stable monastic community and his emphasis on integrating spiritual practice into everyday life.

Biography and Historical Context

Born with the surname Si-ma in Yongning County, Qizhou (modern Wuxue City, Hubei Province), Daoxin began his Buddhist studies at a young age. He met Jianzhi Sengcan, the third Chán Patriarch, at fourteen, an encounter that led to his enlightenment and nine years of discipleship. Sengcan famously instructed Daoxin to remain and spread the Dharma in the south, rather than follow him to Mount Lo-fu.

Daoxin later spent ten years studying with Zhikai at Great Woods Temple on Mount Lu, where he was influenced by the Tiantai and Sanlun schools. He received monastic ordination in 607. A notable event in his life occurred in 617 when he taught the Mahaprajnaparamita Sutra to residents of Ji Province under siege, causing the bandits to withdraw. He eventually settled at East Mountain Temple on Shuangfeng, where he resided for thirty years, cultivating a large community of practitioners.

Daoxin famously refused multiple invitations from Emperor Tai Zong, demonstrating a profound detachment from worldly power and recognition. His steadfastness, even in the face of the emperor's forceful demands, earned him great respect. He died in 651, reportedly after instructing his students to build his stupa and making enigmatic remarks about his succession.

Teachings and Legacy

The teachings associated with Daoxin and his successor, Daman Hongren, are known as the East Mountain Teachings. This period is significant for developing a stable monastic life for Chan practitioners. Dumoulin suggests that the need to sustain a large, isolated community led to the integration of manual labor and administrative duties with meditation, fostering the idea that religious practice should permeate all aspects of existence.

While the historical accuracy of some records is debated, Daoxin's teachings emphasized profound introspection and meditation. He is quoted as saying, "Buddha is the mind. Outside of the mind there is no Buddha." He encouraged earnest meditation, advising students to "Sit earnestly in meditation! Sitting in meditation is basic to all else…." His final words urged his disciples to "drop away" all worldly dharmas and protect this understanding for the future. Daoxin's legacy lies in his role in solidifying Chan Buddhism as a distinct and influential tradition within China.
