1. Acela-Kassapa.-A naked ascetic. He visited the Buddha at Ujuññā in the Kanna-katthala deer-park and asked him if it were true that he disparaged all penance and reviled ascetics. Their conversation is recorded in the Kassapa-Sīhanāda Sutta (D.i.161ff). After the usual four months' probation, he joined the Order and in due course became an arahant (D.i.177; but according to DA.i.363 he was ordained forthwith).
In the Majjhima Nikāya (M.iii.124ff.; also AA.i.171) we are told that he was an old friend of Bakkula Thera, and that after a conversation with him obtained his ordination (under him).
