The difference between the "natural" individuation process, which runs its course unconsciously, and the one that is consciously realized is tremendous. In the first case, consciousness nowhere intervenes; the end remains as dark as the beginning. In the second case, so much darkness comes to light that the personality is permeated with light and consciousness necessarily gains in scope and insight. The encounter between conscious and unconscious has to ensure that the light that shines in the darkness is not only comprehended by the darkness, but comprehends it.
Carl JungIf we feel our way into the human secrets of the sick person, the madness also reveals its system, and we recognize in the mental illness merely an exceptional reaction to emotional problems which are not strange to us. --"The Content of the Psychoses
Carl JungWe live in a world which in some respects is mysterious; things can be experienced which remain inexplicable; not everything which happens can be anticipated. The unexpected and the incredible belong in this world. Only then is life whole. For me the world has from the beginning been infinite and ungraspable.
Carl Jung
