A brahmin who visits the Buddha at Jetavana and asks him various questions on castes and their distinctions, from the point of view of their functions. The Buddha replies that birth’s invidious bar has been laid down by the brahmins, without consulting anybody else; all four castes alike can live the good life, which is the true service, and follow the Dhamma, which is the true wealth. At the end of the discourse Esukārī declares himself to be a follower of the Buddha (M.ii.177 ff).
