The Platform Sutra of the Sixth Patriarch (BDK English Tripitaka)

This record of the life and teachings of Hui-neng, the Sixth Chan (Zen) Patriarch, is an eleventh-century compilation with ancillary materials. It deals with the Buddhist notion that the only criterion of any significance whatsoever is the experience of "seeing the Buddha-nature," realizing one's innate status as an enlightened being.
