Meister Eckhart tells us that in silence we make room in our soul for God and that God delights to be in our soul when we have made room. Should we not then be building mansions of silence in our souls to welcome Love's Holy Presence.
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.
