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.
I have a friend who speaks of knowledge as an island in a sea of mystery. . . . We dredge up soil from the bed of mystery and build ourselves room to grow. And still the mystery surrounds us. It laps at our shores. It permeates the land. Scratch the surface of knowledge and mystery bubbles up like a spring.
