"Man knows that, by himself, he cannot respond to his own fundamental need to understand. However much he is deluded and still deludes himself that he is self-sufficient, he experiences his own insufficiency. He needs to open himself to something more, to something or to someone that can give him what he lacks, he must come out of himself towards the One who is able to fill the breadth and depth of his desire. Man bears within him a thirst for the infinite, a longing for eternity, a quest for beauty, a desire for love, a need for light and for truth which impel him towards the Absolute; man bears within him the desire for God. And man knows, in a certain way, that he can turn to God, he knows he can pray to him." - Pope Benedict XVI, General Audience, Man in Prayer (2), 11 May 2011.
