議論で誰も自分に敵わないと確信していた自慢屋の論客サッチャカ（Saccaka）が、我の本質をめぐって仏陀と公開討論に引き込まれ、仏陀が泰然としている一方で汗まみれになるまで次第にあらゆる点で譲歩を強いられ、最後には仏陀と弟子たちを食事に招待するという経。

A discourse describing how the boastful debater Saccaka, confident no one could match him in argument, is drawn into a public debate with the Buddha over the nature of the Self, is gradually forced to concede every point until he is drenched in sweat while the Buddha remains composed, and ends by inviting the Buddha and his disciples to a meal.
