śvā śṛgālo vako gṛdhro vyāḍaḥ kaṅkastathā kramāt /
bhrātṛbhāryāñca durbuddhiryo dharṣayati pāpakṛt //

“Moreover for improperly touching another’s wife he is born a horrible wolf. And the foolish sinner who violates his -brother’s wife becomes a dog, a jackal, a heron, a vulture, a snake, and a bird of prey,[12] by degrees. And the sinner, who has violated his friend’s wife, his guru’s wife, and the king’s wife, becomes a cock-cuckoo when released from hell. The man of lustful soul is born a hog.
