Krishna is God, the Supreme Personality of Godhead. He is the original and primeval person who is simultaneously expanded everywhere throughout existence and yet is still situated in His eternal abode in His original, transcendental form. He is the all-powerful, all-knowing, and all-merciful being. He is the chief eternal living entity amongst all eternal living entities who are His parts. He is responsible for fulfilling all the desires of the subordinate living entities since time immemorial.
