The soul of a man

"The soul of a man, left to it's own natural level, is a potentially lucid crystal left in darkness. It is perfect in its own nature, but it lacks something that it can only receive from outside and above itself. But when the light shines on it, it becomes in a manner transformed into light and seems to lose its nature in the splendor of a higher nature, the nature of the light that is in it."-- Thomas Merton, The Seven Storey Mountain
