Only when we are silent can we begin to hear the voice that is truly our own, the still, small voice within. The source of this voice, which may be without sound, and yet is heard, is called by many different names: the inner guide, guardian angel, spirit guide, the collective unconscious, or just plain intuition. Actually, all of us hear the whisperings of this voice every single day of our lives, but many ignore it.
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.
