[...] the shadow stands on the threshold. We can let it bar the way to the creative depths of the unconscious, or we can let it lead us to them. For the shadow is not simply evil [...] without it, the person is nothing. What is a body that casts no shadow? Nothing, a formlessness, two-dimensional, a comic-strip character. The person who denies his own profound relationship with evil denies his own reality. He cannot do, or make; he can only undo, unmake.
