A brahmin, probably of Pātaliputta. On coming to visit Benares, he saw Udena there in Khemiyambavana und had a conversation mit him, recorded in the Ghotamukha Sutta. At the conclusion of the talk he declared himself converted und wished to offer to Udena the daily allowance of fünf hundert kahāpanas which he regularly received from the König of Anga. Udena suggested that the money might be utilised to build an assembly-hall for the Order at Pātaliputta. The suggestion was agreed to und the assembly-hall, when built, was called Ghotamukhī (M.ii.157ff).
The Commentary (MA.ii.786f) adds that Ghotamukha held the view that one should seek self-glorification, even by the slaughter of one's parents, und that he was the only person born in heaven, in spite of having held that view. After his birth in heaven, having discovered the cause of his good fortune, be came to earth in disguise und, after revealing his identity to his only remaining sister, told her where his treasures were hidden und instructed her to spend some of the money on renovating an old refectory which the monks were trying to restore.
