ayājyayājanaṃ kṛtvā pareṣām antyakarma ca
abhicāram ahīnaṃ ca tribhiḥ kṛcchrair vyapohati //

He who has (knowingly) offered a sacrifice for an unworthy person (such as a low-caste person, or an outcast), he who has performed the funeral rites for a stranger, he who has practised magic rites (in order to destroy an enemy), and he who has performed a sacrifice of the kind called Ahîna, (all those persons) may rid themselves of their sins by performing three Krikkhra (Prâgâpatya) penances.
