A Nigaṇṭha, follower of Nāṭaputta. He once visited the Buddha at Nāḷandā, and there followed a discussion on actions and their efficiency. Dīghatapassī reported this discussion to Nāṭaputta and Upāli, who was listening, went, against the advice of Dīghatapassī, to the Buddha and challenged him to a discussion, at the end of which Upāli was converted.
