“If I believe in the intrinsic efficacity of a discipline, I attribute its failure to all kinds of things but not to the discipline itself; so that it does not devalorise itself. If, on the contrary, I have understood the intrinsic inefficacity of the discipline, while not by any means forbidding myself to practice it if I feel the need to do so, a profound lassitude will develop little by little in me which will detach me from this discipline in a real transcendence.”
