According to Jung, the human being deals with the reality of the shadow in four ways: denial, projection, integration and/or transmutation. Filling the conscious mind with ideal conceptions is a characteristic of Western theosophy, but not the confrontation with the shadow and the world of darkness. One does not become enlightened by imagining figures of light, but by making the darkness conscious.
“We carry our past with us, to wit, the primitive and inferior man with his desires and emotions, and it is only with an enormous effort that we can detach ourselves from this burden. If it comes to a neurosis, we invariably have to deal with a considerably intensified shadow. And if such a person wants to be cured it is necessary to find a way in which his conscious personality and his shadow can live together.” (Answer to Job)
“Taking it in its deepest sense, the shadow is the invisible saurian tail that man still drags behind him. Carefully amputated, it becomes the healing serpent of the mysteries. Only monkeys parade with it.” (The Integration of the Personality)
“If you imagine someone who is brave enough to withdraw all his projections, then you get an individual who is conscious of a pretty thick shadow. Such a man has saddled himself with new problems and conflicts. He has become a serious problem to himself, as he is now unable to say that they do this or that, they are wrong, and they must be fought against…
Such a man knows that whatever is wrong in the world is in himself, and if he only learns to deal with his own shadow he has done something real for the world. He has succeeded in shouldering at least an infinitesimal part of the gigantic, unsolved social problems of our day.” (Psychology and Religion)
“To confront a person with his shadow is to show him his own light. Once one has experienced a few times what it is like to stand judgingly between the opposites, one begins to understand what is meant by the self. Anyone who perceives his shadow and his light simultaneously sees himself from two sides and thus gets in the middle.” (Good and Evil in Analytical Psychology)
