Because in trying to articulate what, perhaps, joy is, it has occurred to me that among other things—the trees and the mushrooms have shown me this—joy is the mostly invisible, the underground union between us, you and me, which is, among other things, the great fact of our life and the lives of everyone and thing we love going away. If we sink a spoon into that fact, into the duff between us, we will find it teeming. It will look like all the books ever written. It will look like all the nerves in a body. We might call it sorrow, but we might call it a union, one that, once we notice it, once we bring it into the light, might become flower and food. Might be joy.
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."
