A simple mind is not mysterious. In a simple mind, awareness just is. It's open, transparent. There's nothing complicated about it. For most of us, most of the time, however, it is largely unavailable. But the more we have contact with a simple mind, the more we sense that everything is ourselves, and the more we feel responsible for everything. When we sense our connectedness, we have to act differently... When we can sit and meditate with a simple mind, not being caught by our own thoughts, something slowly dawns, and a door that has been shut begins to open... We see that the present is absolute and that, in a sense, the whole universe begins right now, in each second. And the healing of life is in that second of simple awareness.
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.
