It is necessary that we find God, who cannot be found in noise and unpeace. 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 to us and through us. All our words are useless if they do not come from within.
Silence brings us back to basics, to our senses, to our selves. It locates us. Without that return we can go so far away from our true natures that we end up, quite literally, beside ourselves. We live blindly and act thoughtlessly. We endanger the delicate balance which sustains our lives, our communities, and our planet.
