One of the three Kassapa brothers, the Tebhātika-Jatilā (q.v.). On leaving the world with his brothers and becoming an ascetic, he gathered round him a company of two hundred other ascetics. They all lived at Gayāsīsa, hence his name (Gayāsīse pabbajito ti Gayā Kassapo nāma jāto). When Uruvela-Kassapa was converted, Gayā-Kassapa, with his followers, joined the Order, and at the conclusion of the Adittapariyāya Sutta they all became arahants (Vin.i.33f.; AA.i.165). Gayā-Kassapa is reported (Thag.v.345f) to have said that he used to bathe three times a day at Gayātittha, in order to wash away his sins during the festival of Gayāphaggu.
