Silence has many dimensions. It can be a regression and an escape, a loss of self, or it can be a presence, awareness, unification, self-discovery... Positive silence pulls us together and makes us realize who we are, who we might be, and the distance between these two. Hence, positive silence implies a disciplined choice and what Paul Tillich called the "courage to be." In the long run, the discipline of creative silence demands a certain kind of faith. For when we come face to face with ourselves in the lonely ground of our own being, we confront many questions about the value of our existence, the reality of our commitments, the authenticity of our everyday lives. - Thomas Merton, Love and Living.
