Dona Sutta
Dona Sutta:A brahmin,Dona (probably identical with Dona 1 above),visits the Buddha and asks if it be true that the Buddha does not honour brahmins.The Buddha tells him that there are five kinds of brahmins - the Brahma-like,the deva-like,the bound,the breaker of bonds,and the brahmin-outcast - and,at Dona’s request,describes these in detail (A.iii.223ff).The classification of brahmins given in this sutta is often referred to.E.g.,SNA.i.318,325,etc.
