Jung: Casting a Shadow

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 insasmuch as I become conscious of my Shadow I also remember that I am a human being like any other. Modern Man in Search of a Soul, pg 35
