EKA.
Second Patriarch of the sect. Severed his own arm and presented it to Bodhidharma. In spite of his fanaticism (or because of it) the Founder did not at first regard him with complete confidence and recommended to him the study of the Langkāvatāra Sūtra, not considering him ripe for complete, non-dogmatic Zen. Eka waiting waist-deep in the snow for the Founder to instruct him. Masterpieces of Sesshū, Pl. 45.
