Letting go is never easy. The desire to have, to hold, to possess and to control is part of our nature. But the more powerful part yearns to learn the lesson of growth and openness; to enter the mystery of secret loving without desiring, to live in emptiness and stillness and therefore in a state of receptivity and readiness so that the quality of our being and "our being present to" are all that matter.
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.
