ye vṛttidaṁ patiṁ hitvā
jāraṁ patim upāsate
King Vena was so foolish that he accused the saintly sages of being inexperienced like small children. In other words, he was accusing them of not having perfect knowledge. In this way he could reject their advice and make accusations against them, comparing them to a woman who does not care for her husband who maintains her but goes to satisfy a paramour who does not maintain her. The purpose of this simile is apparent: It is the duty of the kṣatriyas to engage the brāhmaṇas in different types of religious activities, and the king is supposed to be the maintainer of the brāhmaṇas. If the brāhmaṇas do not worship the king but instead go to the demigods, they are as polluted as unchaste women.
