A brahmin of Dunnivittha in Kálinga. He was given a young maiden in repayment of a debt, but because she was praised for her virtues, the other wives in the village grew jealous of her and mocked her as an old man's darling. Thereafter she refused to go to the village well, and suggested that Jújaka should obtain as slaves the children of Vessantara, then living as an ascetic in Vankagiri.
After many adventures Jújaka found Vessantara, was allowed to have the two children, Jáli and Kanhajiná, and having tied their hands together, took them away. After he had travelled sixty leagues, the gods led him to Jetuttara, where the children's grandfather reigned as king. The king bought the children back from Jújaka at a very great price and gave him choice foods to eat. Jújaka, having over-eaten and being unable to digest the food, died on the spot (J.vi.521-81). He is identified with Devadatta (J.vi.593).
The wife of the brahmin who went for alms to Bávarí was a descendant of Jújaka. His descendants were still living in Dunnivittha, even in the Buddha's day (AA.i.183).
