仏陀が一握りの葉を譬えとして用い、自らが明かした苦・その原因・滅・道こそが涅槃に導くものであり、それは明かさなかった遥かに膨大な知識とは異なると説いた経

A discourse in which the Buddha, using a handful of leaves as simile, teaches that what he has revealed — suffering, its cause, cessation, and the path — is what conduces to nibbāna, unlike the vastly greater unrevealed knowledge.
