A thera. At the time of the Vajjian heresy, he was the attendant of the elder Revata and had been twenty years in the Order. The Vajjī of Vesāli went to him and, after much persuasion, succeeded in getting him to accept one robe from them.

In return for this he agreed to say before the Saṅgha that the Pācīnaka Bhikkhus held the true Doctrine and that the Pātheyyaka monks did not. Thereafter Uttara went to Revata, but Revata, on hearing what he had done, instantly dismissed him from attendance upon him. When the Vesāli monks were informed of the occurrence, they took dependence (nissaya) from Uttara and became his pupils. Vin.ii.302-3; Mhv.iv.30.
