It is what the psychologist Carl Jung called the shadow. It contains all the parts of ourselves that we have tried to hide or deny. It contains those dark aspects that we believe are not acceptable to our family, friends, and most importantly, ourselves. The dark side is stuffed deeply within our consciousness, hidden from ourselves and others. The message we get from this hidden place is simple: there's something wrong with me. I'm not okay. I'm not lovable. I'm not deserving. I'm not worthy.
