An ascetic who dwelt on the banks of the Nairañjanā river who was converted by the Buddha at Uruvelā (from whence his name) shortly after the Buddha attained enlightenment (bodhi). He was one of three brothers who between them had many hundred followers. The Buddha resided with Uruvela-Kassapa for a time and performed many feats of magical power, including defeating a fire-breathing demon (nāga). Impressed by these powers, the ascetic sought ordination along with his brothers and their followers. They all became Arhats when the Buddha preached the Fire Sermon to them. The scene of Uruvela-Kassapa's conversion is recorded at Sāñcī.
