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.
