Take the biblical phrase: “God is love” (1 John 4:18). Repeat it again and again in your heart. As you do so, savor it, relish it and you will find that it is sweet as honey in your mouth. “God is love … God is love … God is love.” Repeat it at your own pace and rhythm. After some time you may wish to stop repeating it and be silent, without words and without thought. This is a rich silence, a sacred silence, a precious silence, a mystical silence. This is indeed the threshold of mystical prayer. So treasure that silence lovingly until after some time (perhaps after one minute or perhaps after ten minutes) you get all distracted, and then you return to your biblical words: “God is love … God is love … God is love.”
