The highest point of life may be to live in a state of pure flow, a "now-state" without past or future, in which prediction and control are not factors—a state of continual, instant-by-instant adaption to the unknown.
~ Joseph Chilton Pearce
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.
