Creativity and the Shadow

Robert Johnson writes in his book, "Owning Your Shadow," that our dark side or shadow--which is that undeveloped side of ourselves that we project onto others--can be a useful tool for creativity. If we can get the courage to "own" our shadow--to take responsibility for it--then we can harness it and transform it into a powerful force. "We need to connect with dark side for out own development," he writes. He concludes that the shadow gives us energy and vitality. How we use that energy is up to us. Any thoughts?
