《長部》第四經，記述佛陀與婆羅門 Soṇadaṇḍa 的對話，引導對方承認出身並非成為真婆羅門的關鍵、唯有德行才是根本，進而闡明何為良善的生活。

The fourth sutta of the Dīghanikāya, recording a discussion in which the Buddha leads the brahmin Soṇadaṇḍa to acknowledge that birth is unimportant to being a true brahmin and that only a virtuous life matters, then expounds what that good life entails.
