Who · King Vena, King Aṅga, Bhṛgu and the sages
The story · In the account of Dhruva’s descendants, Vena appears as a cruel boy who needlessly killed innocent deer. In King Aṅga’s absence, the sages made Vena king to protect the people, but the king himself became a source of disturbance. They offered him good advice about righteous rule and worship of the Supreme Personality of Godhead. Vena rejected their counsel and demanded that the offerings of sacrifice be given to him instead. After his death, the sages feared disorder and resolved to preserve the family of the saintly King Aṅga.
What it teaches · A pious ruler supports citizens in worshiping the Supreme Personality of Godhead through their occupations. Royal power does not justify demanding the worship due to the Lord.
