Everything is done automatically by the laws of nature, which work under the direction of the Supreme Personality of Godhead. There is no question of doing anything independently, for one who has put himself in this material atmosphere is fully under the control of natures laws. Our main business, therefore, should be to get out of this conditioned life and again become situated in spiritual existence. Only due to ignorance does a person think, I am a demigod, I am a human being, I am a dog, I am a cat, or, when the ignorance is still further advanced, I am God. Unless one is fully self-realized, ones life of ignorance will continue.
