The soul of man, left to its 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 in 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.
So the natural goodness of man, his capacity for love which must always be in some sense selfish if it remains in the natural order, becomes transfigured and transformed when the Love of God shines in it. What happens when a man loses himself completely in the Divine Life within him? This perfection is only for those who are called the saints – for those rather who are the saints and who live in the light of God alone. For the ones who are called saints by human opinion on earth may very well be devils, and their light may very well be darkness. For as far as the light of God is concerned, we are owls. It blinds us and as soon as it strikes us we are in darkness. People who look like saints to us are very often not so, and those who do not look like saints very often are. And the greatest saints are sometimes the most obscure.
-Thomas Merton
