God is the friend of silence. See how Nature -- trees, flowers, and grass -- grow in stillness; how stars, moon, and sun run their course in silence. The more we receive through quiet prayer, the more we can give in the activity of our daily lives. In essence, it is not what WE say, but what GOD says in us and through us. All our words are useless if they do not come from within.
Among all the different arts, the art of music has been especially considered divine, because it is the exact miniature of the law working through the whole universe.
