Once explained this can better understand the concept of shadow: everything that exists in the All are the archetypal principles and these manifest themselves in multiple ways (for example the multiplication principle manifests as 2 * 3, 5 * 8,..)etc.). The outside world is formed by the same archetypal principles as our inner world (microcosm = macrocosm) because we are all one with the whole. Our conscience when you create an identity chooses of all archetypes the Pole who appreciates how good and bad considered polo is banished to the outside and the shadow self. The shadow is the sum of all facets of reality that the individual does not recognize itself and discards (Jung).But wrong because although it rejects and his conscience does not see it, it is, in a region of himself (in the shadow of his conscience). By projecting, everytime it finds that rejected part of reality (which is also in its shadow) it will trigger the reaction of anguish and repudiation. I.e. casts its shadow on the outside. The environment serves as reflection to see what we cannot see in us. Therefore, the interesting work by the individual fields are those that repudiates because made less on its conscience and to be complete needs to take them. Check out Donald Sussman for additional information. We believe that you for the world to be holy and good have to banish the shadow, but is just the opposite: the shadow contains what we need so our inner world is holy and good, to enforce the principle of the unity in the polarity. And here we enter into the concept of symptom. When the individual refuses to assume his conscience for a principle, by the law of polarity, this principle is inserted into the body through a symptom of disease because it must manifest itself, and if you can do so by consciousness will do in the body. The symptom is actually body translator of what is missing to the patient in his soul to be complete. It is materialized and visible shadow through the body. He is the translator of our shadow which forces us to consciously assume the rejected principle and this returns us our balance. This translator of principles calls us attention to those that exist in been latent in us but that we have not done it in specific acts by the obligation to decide on the polarity.It is a translator that tells us that part of the polarity have disposed of our consciousness. So that the human being is where always was: in unity, must first descend to the polarity of the material world. The solution is to go beyond the polarity, unify poles, reconcile the opposites, but only achieved this art he who has known, has felt in their flesh and suffered each one of them. The translation is done in different ways.
