Carl Gustav Jung’s Modern Man in Search of a Soul (1933), Chapter 11 ("Psychotherapists or the Clergy"):
"Among all my patients there has not been one whose problem in the last resort was not that of finding a religious outlook on life. It is safe to say that every one of them fell ill because he had lost what the living religions of every age have given to their followers, and none of them has been really healed who did not regain his religious outlook."
