I once heard the pianist, Arthur Rubinstein, being interviewed. At one point he was asked to share his experience of playing Chopin's Nocturnes. He said in effect, "I do not know what it is. But over and over again I have had the experience of sitting in a crowded concert hall playing the Nocturnes and I can feel everyone in the room waiting for the next note." In this moment of waiting, all present find their contemplative community in their oneness with one another in the boundless mystery that enraptures them.
God is the friend of silence. See how nature -- trees, flowers, grass -- grow in silence; see the stars, the moon, the sun, how they move in silence... The more we receive in silent prayer, the more we can give in our active life. We need silence to be able to touch souls. The essential thing is not what we say, but what God says to us and through us. All our words will be useless unless they come from within.
