He belonged to a brahmin family of Sāvatthi, and used to go to the vihāra to hear the Buddha preach. One day the Buddha preached for his special benefit, and, very much moved, he joined the Order. But because of his immaturity of knowledge, he continued some time without application. Later he was impressed by another sermon of the Buddha, and became devoted and intent, attaining arahantship soon afterwards (Thag.vs.90. ThagA.i.189).
He is evidently identical with Adhichattiya (or Chattādhichattiya) of the Apadāna (Ap.i.170). In the past he erected a parasol over the cetiya of Atthadassī Buddha.
