One of the Bhāradvāja brothers. On hearing that the eldest of the clan had entered the Order, he went to the Buddha, and, unable to speak for rage, sat on one side, sulking. The Buddha taught him, and he was pleased and entered the Order, becoming an Arahant in due course (S.i.164; DhA.iv.163).
The Commentary explains (SA.1.178 f) that he had earned large profits by running a shop for different kinds of excellently prepared conjey (kañjikā). The name Bilaṅgika (bilaṅga being another name for such preparations) was given him by the Recensionists at the Third Council.
