" Everything in this world seems to be created in pairs. If there is a man, there is a woman—in almost equal numbers. In the same way, there is pleasure with pain, love with hatred, wisdom with ignorance, passion with repulsion, ecstasy with depression, and so on. The world seems to have been divided into two attributes—good and evil. Even God seems to be divided--God Himself and His counterpart—the Devil. "
