A. I. Allenby visited Carl Jung soon after World War II. This excerpt from his description of his visit is from the book C. G. Jung Speaking, page 158.
Another time Jung reverted to the problem of self-doubt, using a further example by way of illustration. “Our needs and desires are always active,” he said. “Trouble occurs only if they are active in the unconscious, if we do not take them consciously in hand so as to give them a definite form and direction. If we refuse to do this we are dragged along by them to become their victim. Then they are like a sledge rushing downhill snow, with no one at the steering-ropes. You must place yourself firmly at the steering-ropes, not hang on at the back or, worse, be unwilling to take the ride at all — that only lands you in panic. Our unconscious energies give momentum to our journey through life and, if we direct our course, our actions will have strength; we may even sense that God is behind us.”
