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.
