King Parīkṣit inquired: My dear brāhmaṇa, the Supreme Personality of Godhead, Viṣṇu, being everyone’s well-wisher, is equal and extremely dear to everyone. How, then, did He become partial like a common man for the sake of Indra and thus kill Indra’s enemies? How can a person equal to everyone be partial to some and inimical toward others?
