Listening creates a holy silence. When you listen generously to people, they can hear truth in themselves, often for the first time. And in the silence of listening, you can know yourself in everyone. Eventually you may be able to hear, in everyone and beyond everyone, the Unseen singing softly to itself and you.
The discipline of silence doesn't mean just taking a short vacation from the spoken word. It also means giving complete relaxation to the muscles, the tissues, the tongue itself. A modern writer once said: "Knowledge has never been known to enter the head via an open mouth." It is when you become completely silent that you are able to absorb knowledge. God speaks in silence. The discipline of silence is essential on the path.
