God is one, and God does not belong to this or that religion. In Kali-yuga, different religious sects consider their God to be different from the God of others, but that is not possible. God is one, and He is appreciated according to different angles of vision. In this verse, the word kaivalyat means that God has no competitor. There is only one God. In the Svetasvatara Upanisad (6.8) it is said, na tat-samas cabhyadhikas ca drsyate: “No one is found to be equal to Him or greater than Him.” That is the definition of God.
