Our mind has its history, just as our body has its history. You might be just as astonished that man has an appendix, for instance. Does he know he ought to have an appendix? He is just born with it....Our unconscious mind, like our body, is a storehouse of relics and memories of the past. A study of the structure of the unconscious collective mind would reveal the same discoveries as you make in comparative anatomy. We do not need to think that there is anything mystical about it.
Carl JungThe dream arises from a part of the mind unknown to us, but none the less important, and is concerned with the desires for the approaching day.
Carl JungThe term "self" seems a suitable one for the unconscious substrate whose actual exponent in consciousness is the ego. The ego stands to the self as the moved to the mover, or as object to subject, because the determining factors that radiate outward from the self surround the ego on all sides and are therefore supraordinate to it. The self, like the unconscious, as an a priori existent out of which the ego evolves. It is, so to speak, an unconscious prefiguration of the ego. It is not I who create myself; rather, I happen to myself.
Carl JungWhen we must deal with problems, we instinctively resist trying the way that leads through obscurity and darkness. We wish to hear only of unequivocal results, and completely forget that these results can only be brought about when we have ventured into and emerged again from the darkness. But to penetrate the darkness we must summon all the powers of enlightenment that consciousness can offer.
