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.
Be constant in your practice, and one day the One who gave you the desire for the prayer of the heart will give you that prayer itself. When your heart's intention is fixed on God, it will keep lit the incense of your prayer, and wind of distraction will not put it out. do not worry about stray thoughts; they may come and go, but they will not take your attention away from God.
