A pupil of Brahmāyu. He was sent by his teacher from Mithilā to Videha, to find out if the Buddha bore the thirty-two marks of a Great Man. Having made sure of the presence of all the thirty-two marks on the Buddha’s person, he dogged the Buddha’s footsteps for seven months, in order to observe his deportment in his every posture. At the end of that period, he returned to Brahmāyu and reported what he had seen (M.ii.134 ff; SnA.i.37). Buddhaghosa says (MA.ii.765) that Uttara became known as Buddhavīmaṃsaka-māṇava on account of his close watch over the Buddha.
