The experience of solitude is necessary because only in solitude and silence is the living God revealed as the binding source of all that is. The veil is lifted, and we begin to see the wonderful possibilities of life together that surround and inhabit us. This means that, at our worst and darkest moments, we can affirm that we are God's handiwork, that God's image has marked us forever, that the most real thing about us is the Spirit who dwells in every human heart. We may be fundamentally and utterly nothing, we may be creatures marked for death, but we are peculiar beings whose very emptiness has been designed to be inhabited by nothing less than the living God. And it is in the living God that we meet one another. The life of prayer revolves around two poles: solitude and community. God is encountered in both places.
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.
