Our psyche is set up in accord with the structure of the universe, and what happens in the macrocosm likewise happens in the infinitesimal and most subjective reaches of the psyche
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.
Carl JungAn old man who cannot bid farewell to life appears as feeble and sickly as the young man who is unable to embrace it.
Carl JungI use [Heraclitus' discovery of] enantiodromia for the emergence of the unconscious opposite in the course of time. This characteristic phenomenon practically always occurs when an extreme, onesided tendency dominates conscious life; in time an equally powerful counterposition is built up, which first inhibits the conscious performance and subsequently breaks through the conscious control.
Carl Jung
