《长部》第四经，记述佛陀与婆罗门 Soṇadaṇḍa 的对话，引导对方承认出身并非成为真婆罗门的关键、唯有德行才是根本，进而阐明何为良善的生活。

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.
