Then the Buddha said to Vappa, “Vappa, we can discuss this. But only if you grant what should be granted, and reject what should be rejected. And if you ask me the meaning of anything you don’t understand, saying: ‘Sir, why is this? What’s the meaning of that?’” “Sir, let us discuss this. I will do as you say.”

“What do you think, Vappa? There are distressing and feverish defilements that arise because of instigating bodily activity. These don’t occur in someone who refrains from such bodily activity. They don’t perform any new deeds, and old deeds are eliminated by experiencing their results little by little. This wearing away is apparent in the present life, immediately effective, inviting inspection, relevant, so that sensible people can know it for themselves. Do you see any reason why defilements giving rise to painful feelings would defile that person in the next life?” “No, sir.”
