A monk of Rājagaha. One day, as he walked through the street, a woman asked him to stop for a moment that she might worship him, and, raising the end of his robe, took his penis into her mouth. A doubt arose in his mind as to whether any blame attached to him and he consulted the Buddha, who said that as Sundara had not acquiesced in the act, he was blameless. Vin.iii.36
