Unless we live all our lives in the torment of the contradictions, as C.G. Jung insists, then we’re not human. We can’t become whole. If you’re stuck, and you don’t know what to do, stuck between two opposites, and you allow them each to live within you, then a small transformation of the ego takes place. It becomes related to the Self instead of identifying with it. 

Helen Luke, 1904 – 1995, Jungian Analyst and writer
