A devaputta. He visited the Buddha late one night at Jetavana and uttered several stanzas, admonishing monks to train themselves in their tasks, laying particular stress on the cultivation of Jhāna (S.i.46).

Buddhaghosa says (SA.i.82) that Kassapa had heard the Buddha teach the Abhidhamma in Tāvatiṃsa. Having heard only a portion of the doctrine and not being sure of the admonition given by the Buddha to the monks regarding the practice of Jhāna-vibhaṅga, Kassapa thought he could supply the omission. The Buddha, knowing his capabilities, allowed him to give his views, and expressed his approval at the end of Kassapa’s speech.
