1. Madhura Sutta. Avantiputta, king of Madhurá, visits Mahá Kaccána, who is staying at the Gundávana in Madhurá, some time after the Buddha's death, and questions him regarding the brahmin claims to superiority over other castes. Kaccána points out that wealth confers power on all, not only on brahmins. A brahmin experiences the result of his actions both good and bad, in this world and in the next, just as do members of other castes. A brahmin ascetic receives no more homage than an ascetic of other castes. Avantiputta accepts the Buddha's Faith. M.ii.83 90; cp. Ambattha Sutta; for a discussion see Dial.i.105.
2. Madhura Sutta. On the five disadvantages of Madhurá:
The Commentary explains (AA.ii.646) that the Buddha, during a tour, once entered Madhurá, and was on his way to the inner city. But a certain heretic yakkhiní stood before him naked, stretching out her arms, her tongue out. The Buddha thereupon turned back and went to the vihára, where the people entertained him and the monks.
