True thanking is to enjoy God. Gratitude is a true understanding of who we really are. With reverence and awe we turn ourselves around toward the work God leads us to do, enjoying and thanking with our real selves.
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."
