1. Káyasakkhi Sutta.-Savittha and Mahá-Kotthita once visit Sáriputta. Sáriputta asks them: Which is the most excellent - one who has testified to the truth with body, one who has won view, or one released by faith? Savittha prefers the one released by faith, Mahá-Kotthita the one who has testified to the truth with body, while Sáriputta's preference is for the one who has won view, for in him insight is most developed.
