A Pacceka Buddha, mentioned in the list in the Isigili Sutta. MN.iii.70
A monk whose verse is in the Theragāthā. Thag.67
A brahmin. He once went to the Buddha and asked him if he thought well of sacrifices. The Buddha replied that he was opposed to sacrifices which involved the slaughter of animals, but sacrifices not necessitating butchery, such as, for instance, a long-established charity, an oblation for the welfare of the family, had his approval. AN.ii.42
The same Nikāya AN.iv.285f. records another visit of Ujjaya wherein he tells the Buddha that he wishes to observe a period of retreat, and asks for a teaching which will bring welfare both in this world and in the next.
