“I am not attacking any particular version of God or gods. I am attacking God, all gods, anything and everything supernatural, wherever and whenever they have been or will be invented. (p. 57 of the Black Swan paperback edition of 2007)”

Context: When I say I am the Avatar, there are a few who feel happy, some who feel shocked, and many who hearing me claim this, would take me for a hypocrite, a fraud, a supreme egoist, or just mad. If I were to say every one of you is an Avatar, a few would be tickled, and many would consider it a blasphemy or a joke. The fact that God being One, Indivisible and equally in us all, we can be nought else but one, is too much for the duality-conscious mind to accept. Yet each of us is what the other is. I know I am the Avatar in every sense of the word, and that each one of you is an Avatar in one sense or the other.
It is an unalterable and universally recognized fact since time immemorial that God knows everything, God does everything, and that nothing happens but by the Will of God. Therefore it is God who makes me say I am the Avatar, and that each one of you is an Avatar. Again, it is He Who is tickled through some, and through others is shocked. It is God Who acts, and God Who reacts. It is He Who scoffs, and He Who responds. He is the Creator, the Producer, the Actor and the Audience in His own Divine Play.
