"Have you got a local mind? Broaden it! Have you got an international mind? Broaden it! Have you got a universal mind? It is not enough, because there are other universes. Broaden it! Broaden your mind till you get a multi-universal mind! And yet, this is not enough too! Broaden it! Leave your village; leave your city; leave your country; leave the earth; leave the universe; leave all the universes! Don't let your mind to cast anchor in any port! Narrow mind is the greatest enemy of the truth! The best mind is the one which has no frontiers!"
