"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." ~ Carl Gustav Jung, Psychology and Religion

"The shadow is a moral problem that challenges the whole ego-personality, for no one can become conscious of the shadow without considerable moral effort. To become conscious of it involves recognizing the dark aspects of the personality as present and real. This act is the essential condition for any kind of self-knowledge." ~ Carl Gustav Jung, Aion

"Unfortunately there can be no doubt that man is, on the whole, less good than he imagines himself or wants to be. Everyone carries a shadow, and the less it is embodied in the individual’s conscious life, the blacker and denser it is. If an inferiority is conscious, one always has a chance to correct it. Furthermore, it is constantly in contact with other interests, so that it is continually subjected to modifications. But if it is repressed and isolated from consciousness, it never gets corrected." ~ Carl Gustav Jung, Psychology and Religion

"We know that the wildest and most moving dramas are played not in the theatre, but in the hearts of ordinary men and women who pass by without exciting attention, and who betray to the world nothing of the conflicts that rage within them except possibly by a nervous breakdown. What is so difficult for the layman to grasp is the fact that in most cases the patients themselves have no suspicion whatever of the internecine war raging in their unconscious. If we remember that there are many people who understand nothing at all about themselves, we shall be less surprised at the realization that there are also people who are utterly unaware of their actual conflicts." ~ Carl Gustav Jung, New Paths in Psychology

"In contrast to the meditation found in yoga practice, the psychoanalytic aim is to observe the shadowy presentation - whether in the form of images or of feelings - that are spontaneously evolved in the unconscious psyche and appear without his bidding to the man who looks within. In this way we find once more things that we have repressed or forgotten. Painful though it may be, this is in itself a gain - for what is inferior or even worthless belongs to me as my shadow and gives me substance and mass. How can I be substantial if I fail to cast a shadow? I must have a dark side also if I am to be whole; and inasmuch as I become conscious of my shadow I also remember that I am a human being like any other." ~ Carl Gustav Jung, Modern Man in Search of a Soul
