Lord Visnu Himself, the Supreme Personality of Godhead, is the reservoir of all pleasure. Therefore, what benefit would He derive from siding with the demigods? What interest would He fulfill in this way? Since the Lord is transcendental, why should He fear the asuras, and how could He be envious of them?
