You cannot buy the revolution. You cannot make the revolution. You can only be the revolution. It is in your spirit, or it is nowhere.
Silence is not a thing we make; it is something into which we enter. It is always there. We talk about keeping silence. We keep only that which is precious. Silence is precious, for it is of God. In silence all God's acts are done; in silence alone can God's voice be heard, God's word spoken.
