Here in the material world we have practical experience that a superior person is worshiped by an inferior one. Similarly, pūruṣottama, the greatest, the Supreme Personality of Godhead, Kṛṣṇa, or Lord Viṣṇu, is always worshiped by others. Pṛthu Mahārāja therefore decided to engage in the service of the lotus feet of Lord Viṣṇu. Pṛthu Mahārāja is considered to be an incarnation of Lord Viṣṇu, but he is called a śaktyāveśa incarnation.
