Silence has many dimensions. It can be a regression and an escape, a loss of self, or it can be presence, awareness, unification, self-discovery. Negative silence blurs and confuses our identity, and we lapse into daydreams or diffuse anxieties. Positive silence pulls us together and makes us realize who we are, who we might be, and the distance between the two. Hence, positive silence implies a choice, and what Paul Tillich called the "courage to be."
You are free before the sun of the day, and free before the stars of the night: And you are free when there is no sun and no moon and no star. You are ever free when you close your eyes upon all that is.
