A Paribbājaka, nephew (sister's son) of Sāriputta.
He visited the Buddha at Sūkarakhatalena and the Buddha preached to him the Dīghanakha Sutta, at the end of which he became a sotāpanna.
In the sutta he is addressed as Aggivessana (M.i.497f; ThagA.ii.95; DhA.i.79).
He was originally an Annihilationist (MA.ii.477). Perhaps he is the heretic brahmin, nephew of Sāriputta, who was admonished by Moggallāna because he expressed great repugnance at the sight of Kassapa. Thag.1108ff; ThagA.ii.180.
