We need only to let God's mysterious and silent presence within us to become more and more what shapes us and everything we do. We need to learn the value of silence, stillness, and quiet because it is the way into our human heart, into our center where God dwells.
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.
