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."
The notion of silence appears to unsettle—or puzzle—no small number of people of all walks of life...Something as "unproductive" as silence is not often taken seriously. The evaluation of silence differs from culture to culture. In the West, if you notice that someone is silent for a prolonged period of time, the tendency might be to ask, "are you all right?" Or the silence might be interpreted as a sign of unbalanced introversion or isolation or passive aggression. In India, they would say of the silent one, Ah muni! (Ah, there is a holy soul!)
