tato yavīyasaḥ patnīṃ gautamasyābhyapadyata
kṛtāvalepāṃ tāṃ matvā so 'naḍvāniva na kṣamaḥ //

On one occasion he met the wife of his younger brother's son, Gautama, and, in spite of her being with child, he taking the laws relating to cattle to be of superior importance, did not desist from her, and caught hold of her with a violent jerk and enjoyed himself in her company, though she was like his daughter-in-law in relation. Knowing about futurity, he began to dilate upon the cattle law, when that lady said:—"You going against nature are behaving like an ox, and without having regard for the rules of prohibited relationships in sexual intercourse; but following the natural law of the beast, you have committed an incest on your daughter. Consequently, I forsake you base and mean, and now go away on account of your doings."—53-56.
