Fiber and resilience are only possible in a man who is humble enough to admit the need to anchor his spirit in something greater. Only those whose mission does not require virtue will claim otherwise, since virtue is necessarily a continuous effort, contrary to the comfort of matter. There is no man whose spirit does not oscillate, and the higher the spirit, the more it is capable of oscillating. To realize this is to admit the need for a support, outside oneself, to push one towards the ideal that one has defined.
