Shítóu Xīqiān (700-790) Shih-t'ou Hsi-ch'ien; was an 8th-century Chinese Chán (Zen) Buddhist teacher and author. All existing branches of Zen throughout the world are said to descend either from Shitou Xiqian or from his contemporary Mazu Daoyi.[2]
Shítóu does not appear to have been influential or famous during his lifetime: He was a little-known teacher who led a reclusive life and had relatively few disciples. For decades after Shitou's death, his lineage remained an obscure provincial tradition.[2] -- Wiki
