At a certain point, you say to the woods, to the sea, to the mountains, the world, Now I am ready. Now I will stop and be wholly attentive. You empty yourself and wait, listening. After a time you hear it: there is nothing there. There is nothing but those things only, those created objects, discrete, growing or holding, or swaying, being rained on or raining, held, flooding or ebbing, standing, or spread. You feel the world's word as a tension, a hum, a single chorused note everywhere the same. This is it: this hum is the silence. Nature does utter a peep - just this one. The birds and insects, the meadows and swamps and rivers and stones and mountains and clouds: they all do it; they all don't do it. There is a vibrancy to the silence, a suppression, as if someone were gagging the world. But you wait, you give your life's length to listening, and nothing happens. The ice rolls up, the ice rolls back, and still that single note obtains. The tension, or lack of it, is intolerable. The silence is not actually suppression: instead, it is all there is.
