マンゴー林のある場所で微笑んだ仏が、初めて白髪を見て世を捨てた王の話をアーナンダに語り、その王の伝統が梵天界へ導くのみだったのに対し、自らの教えは完全な悟りへ導くと説明する経。

A discourse in which the Buddha, smiling at a certain spot in a mango grove, tells Ānanda the story of a king who renounced the world on seeing his first grey hair, explaining that while that king’s tradition led only to the Brahmā world, the Buddha’s own teaching leads to full enlightenment.
