Osho says in his book, Ah, this!, "God can neither be proved or disproved; it is not an argument. God is not a hypothesis, it is not a theory: it is experience. The Master is living evidence." p.10
I had a friend who got upset when I mentioned that God is not a noun but a verb. She acted indignant and demanded, "What do you mean by that?"
I couldn't explain it at the time. Now I have better words. I got them from Osho. "Godliness is an experience." I have had it. Rarely, but nonetheless it has occurred. I have been calling it "grace," but now I sense that it is God.
