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.
At first, even one minute spent in unaccustomed prayer will seem as endless as an empty silence or a blank stillness; but these periods of quiet can be lengthened profitably, and these times of silent stillness can become alive, eventually becoming the most rewarding experiences of the day, as one discovers how much God has to say to those who will listen. "In quietness and in confidence shall be your strength." A person who does not understand another's silences will not understand their words either.
