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.
When we are endowed with the Wisdom of the heart, but do not have access to knowledge, we are ignorant. Then we only believe what we see, or what has been proven to our satisfaction. Since it does not occur to us that we may be endowed with supernal wisdom, we do not open ourselves to the mystery of the Spirit that invisibly permeates the created world. So long as we limit our explorations and activities to the visible world as though that were all that existed, we must remain blind to the transcendent beauty of the eternal world.
