Did God create man or man created God?
Both. God created man and man created God. Isn’t it funny? Man created different concepts of God, but again, what is God? Is He somebody sitting up there who just created something and went away? No, he is the summum bonum of creation. It is the one thing by which everything has happened, and in which everything is. You may call it God.
So according to the Vedanta, it is: Asti (existence), Bhati (consciousness), Preeti (love). It is, it shines and it is love, and that’s what the whole world is.
This also could become one of the concepts that you have in your mind, unless and until you start feeling it as an authentic reality in your life; as true as a pain you feel in your feet, when you have one.
