中部の第八十二経で、ラッタパーラの出家と、彼が後にクル国王に説明した、贅沢な生活を捨てさせた四つの真理—世界は常に流転し、守護者はなく、何も保持できず、渇愛によって決して満足しない—を語る経

The eighty-second discourse of the Majjhima Nikāya, recounting Raṭṭhapāla’s ordination and his later explanation to a Kuru king of the four truths that led him to renounce a life of privilege — that the world is in constant flux, without a protector, that nothing can be kept, and that craving leaves it forever unsatisfied.
