Loneliness is the Cause, Companionship is the Purpose.

The answer to the question - why would God create such a vast universe just to create humans on one planet? - is companionship. Allow me to explain. There is no separation. Existence is One without division. That which self calls God, the Universe and Humans; it is all One! This One is not external as outside itself. Being outside oneself is impossible. There is only Oneself! Why did Oneself create all this vast diversity? Companionship! Not to be alone. Loneliness is the cause, companionship is the purpose.
