The root of prayer is interior silence. We may think of prayer as thoughts or feelings expressed in words, but this is only one expression. Deep prayer is the laying aside of thoughts. It is the opening of mind and heart, body and feelings -- our whole being -- to God, the Ultimate Mystery, beyond words, thought, and emotions. We do not resist them or suppress them. We accept them as they are and go beyond them, not by effort, but by letting them all go by. We open our awareness to the Ultimate Mystery whom we know by faith is within us, closer than choosing, closer than thinking, closer than choosing -- closer than consciousness itself. the Ultimate Mystery is the ground in which our being is rooted, the source from whom our life emerges at every moment.
~ from OPEN MIND, OPEN HEART by Fr. Thomas Keating
Silence is the language spoken by solitude. There is something awesome and breathtaking about real silence; it is numinous, pulling us out of self-containment and calling us toward the invisible. Spiritual seekers "home in" on silence as homing pigeons to their roost, because therein lies the language for personal communication with the sacred. Silence accompanies us into our innermost selves where we are present to the sacred. When word breaks into that kind of silence, there is communion.
