Dhamma Verses (Dhammapada, KN 2)

18: The Chapter about Stains – 222
The greatest stain
A youth got married but his wife was given to adultery and put
the young man to shame; when he met the Buddha the latter
reminded him that in a previous existence also he was
betrayed by his wife, and then he taught him with this verse.
242. Malitthiyā duccaritaṁ, maccheraṁ dadato malaṁ,
malā ve pāpakā dhammā asmiṁ loke paramhi ca.
Bad conduct is a woman’s stain,
stinginess is a giver’s stain,
wicked actions are indeed stains
both in this world and in the next.
243. Tato malā malataraṁ, avijjā paramaṁ malaṁ,
etaṁ malaṁ pahatvāna, nimmalā hotha, bhikkhavo!
A stain that is worse than that stain,
ignorance is the supreme stain,
after abandoning that stain,
be without stains, O monastics!
