The Vedic literatures state that one who possesses perfect knowledge of the creation and destruction of all entities and who is completely situated in omniscience is to be known as the Supreme Personality of Godhead, Bhagavān. Although many great personalities are sometimes called Bhagavān, ultimately Bhagavān is the one supreme entity who possesses unlimited opulences. Throughout history, many important personalities have been addressed as “lord,” but ultimately there is only one Supreme Lord. In the Lord’s catur-vyūha, or quadruple expansion, the first manifestation is Vāsudeva, who here represents all of the Lord’s expansions in the viṣṇu-tattva category.
