Son of Cālā and nephew of Sāriputta. He was ordained by Khadiravaniya-Revata (Thag.vs.42; ThigA.i.110).

He is mentioned as living at the Kūṭāgārasālā, which place he left when the Licchavis caused disturbance by their visits to the Buddha (A.v.133). In this context he is spoken of as a very eminent elder and was, therefore, evidently an Arahant.
