So bhagavān means you go on searching. When you find a person that nobody is richer than Him, nobody is stronger than Him, nobody is richer than Him, nobody is reputed than Him, nobody is wiser than him, nobody is beautiful, more beautiful than Him, and nobody is renouncer than Him, He is Bhagavān, He is God.
So all these you will find in Kṛṣṇa. That is the significance of Kṛṣṇa. When Kṛṣṇa was present on this material world so nobody could excel Him in any of these opulences. Nobody.
