In the Sahara one day, I climbed over a dune to descend into a deep bowl of sand. Sitting at the bottom I encountered for the first time absolute silence, stillness that is indivisible. For there are two silences: a silence can be no more than the absence of noise, it can be inert; or, at the other end of the scale, there is a nothingness that is infinitely alive, and every cell of the body can be penetrated and vivified by this second silence's activity.
I think the most essential thing in one's life is silence. What is silence? We think if we are quiet, we are silent. But we must come to silence without desire and wanting, otherwise we are not silent.
