If the heart of prayer is listening, what is it we listen to when we pray? The obvious answer is God's voice, yet great care is needed lest we presume the divine voice is like an ordinary human one. The essence of God's voice is silence...To be silent is to empty oneself of the din of transitory distractions so that one becomes fully receptive to the silence that always and everywhere underlies them. The silence thus cultivated is not a void so much as an expectant readiness, a sensitive receptivity, to the stillness hidden in the noise of daily life.
Colin Fletcher, in THE MAN WHO WALKED THROUGH TIME, describes how from moments of peak awareness, there came at last after long solitude and silence, and for the time being, a continuous sense of being one with the rhythm of all life and all time, of being inside as well as outside the life of everything he saw – animals, insects, the living rocks, the wind, the river; and finally, most difficult of all, he could feel even the craziness of modern humanity as part of the unbroken pattern of eternity.
