The cow that was sacrificed and feasted upon by them as the sons of Kauśika was born as Sannati the daughter of Devala and was eventually married to Brahmadatta. Because she had served as an offering of the Pitṛis, she became learned in the Brahma lore, and the king ruled the country to the satisfaction and prosperity of his subjects in conjunction with his noble consort Sanati.—26-27.
