There is a curious and mysterious statement in more than one ancient Hindu philosophical text to the effect that God cannot know himself. What does it mean? The sun's light is needed to end the world's darkness but not needed at any moment by the sun itself since it is all-light: therefore the sun could not shine upon itself, could not light up itself. In the same way, God can gain nothing more by making himself known to himself, since he is already all-knowledge. In this sense only--and not in the sense of inability to know--is the Hindu statement to be interpreted.
