At a certain pitch of religious experience, the heart just wants to sing; it breaks into song. Paradoxically, you could say when silence finds its fullness, it comes to word. As the Book of Wisdom says, "When night in its swift course had reached its halfway point and deep silence embraced everything" -- when night was at its darkest and deepest -- there "the eternal Word leaped from the Heavenly throne": silence burst into song.
The highest level of prayer is not a prayer FOR anything. It is a deep and profound silence, in which we allow ourselves to be still and know God. In that silence, we are changed. We are calmed. We are illumined. Prayer is meant to dissolve the worldly focus, to dissolve our sense of a separate self, to help us detach from the noisy world order.
Prayer is like pouring hot water on an ice cube, melting the cold and encrusted thought forms that still surround our hearts.
