“There is no need to search; achievement leads to nowhere. It makes no difference at all, so just be happy now! Love is the only reality of the world, because it is all One, you see. And the only laws are paradox, humor and change. There is no problem, never was, and never will be. Release your struggle, let go of your mind, throw away your concerns, and relax into the world. No need to resist life, just do your best. Open your eyes and see that you are far more than you imagine. You are the world, you are the universe; you are yourself and everyone else, too! It’s all the marvelous Play of God. Wake up, regain your humor. Don’t worry, just be happy. You are already free!”
