5: The Chapter about Fools – 75
Deeds do not ripen at once
A man burned down the hut of a Paccekabuddha and
eventually was reborn as a snake-ghost, burning for the whole
length of his long body, as was seen by Ven. Moggallāna; the
Buddha confirmed the story, and gave this teaching.
71. Na hi pāpaṁ kataṁ kammaṁ, sajju khīraṁ va muccati,
ḍahantaṁ bālam-anveti, bhasmacchanno va pāvako.
A wicked deed that has been done,
like milk, does not turn all at once,
smouldering, it follows the fool,
like a fire covered with ashes.
