Shin jin Mei
Shin jin mei, Poem on Faith In Mind
This is the oldest Ch’an text and is the work of the third patriarch, Sosan (died in 606). In the Shin jin mei, Sosan studies the profound nature of the mind and transmits the marrow of Bodhidharma and Eka’s teaching, the essence of Zen: neither choosing, nor rejecting; no duality, no discrimination; realize the oneness of the Way.
