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."
Our task in meditation is to allow our unity to be restored and for our scattered parts to move back into their proper harmonious alignment to the center of our being. To do this we must not scatter ourselves further. We concentrate to move towards our center. When our consciousness truly awakens to that center, in silence, then a power is released which is the power of life, the power of the Spirit. In that power we are reformed, reunited, re-created.
