祇陀林で遍歴行者ヴァッチャゴッタに説かれ、世界と生命の起源について推測することの無益さを、消えた火はどこかへ行ったとは言えないという喩えを用いて説く経。

A discourse taught at Jetavana to the wanderer Vacchagotta on the futility of speculating about the origin of the world and of life, using the simile of a fire that, once extinguished, cannot be said to have gone anywhere.
