The world is a totality in itself. It has its own muscles, its own brain, its own limbs, and its own circulation. We are not talking about the totality of the world in the sense that everything should be good and perfect and fantastic, and nobody should acknowledge anything bad. We are talking about reality, in which good is made out of bad and bad is made out of good. Therefore, the world can exist in its own good/bad level, its self-existing level of dark and light, black and white, constantly. Whatever is there, favorable or unfavorable, is workable: it is the universe.
