A brahmin of Magadha who, following his own inclination, became a Paribbājaka. His training ended, he wandered forth and heard of Upatissa and Kolita joining the Buddha's Order. Impressed by their example, he became a monk and, soon after, an arahant. In the time of Atthadassī Buddha, he was an ascetic named Narādakesava and paid homage to the Buddha. Seventeen kappas ago he was a king named Amittatāpana (Thag.vs.87; ThagA.i.185f).
He is evidently identical with Ekadamsaniya of the Apadāna. Ap.i.168f.
