Mystery: it is all around us, and we do not know it. But sometimes when we give it time and space, whether in deep peace or great anguish, it will come up behind us, or meet us face to face, or move within us, changing the way we see everything, and filling our hearts with joy and an upspringing of love that needs no direct object because everything is its object.
We need silence to be able to touch souls. The more we receive in silent prayer, the more we can give in our active life. God is a friend of silence. The essential thing is not what we say, but what God will say through us.
