“The necessary and needful reaction from the collective unconscious expresses itself in archetypally formed ideas. The meeting with oneself is, at first, the meeting with one's own shadow. The shadow is a tight passage, a narrow door, whose painful constriction no one is spared who goes down to the deep well. But one must learn to know oneself in order to know who one is. For what comes after the door is, surprisingly enough, a boundless expanse full of unprecedented uncertainty, with apparently no one inside and no one outside, no above and no below, no here and no there, no mine and no thine, no good and no bad. It is a world of water, where all life floats in suspension; where the realm of the sympathetic system, the soul of everything living, begins; where I am indivisibly this and that; where I experience the other in myself and the other-than-myself experiences me.No, the collective unconscious is anything but an encapsulated personal system; it is sheer objectivity, as wide as the world and open to all the world. There I am the object of every subject, in complete reversal of my ordinary consciousness, where I am always the subject that has an object. There I am utterly one with the world, so much a part of it that I forget all too easily who I really am. "Lost in oneself" is a good way of describing this state. But this self is the world, if only a consciousness could see it. That is why we must know who we are."―from_Archetypes of the Collective Unconscious_”
