“My principle anguish and the source of all my joys and sorrows from my youth onward has been the incessant, merciless battle between the spirit and the flesh.

“The dual substance of Christ-the yearning, so human, so superhuman, of man to attain to God, or more exactly, to return to God and identify himself with him-has always been a deep inscrutable mystery to me. This nostalgia for God, at once so mysterious and so real, has opened in me large wounds and also large flowing springs.”

  – Nikos Kazantzakis , The Last Temptation of Christ
