There is in all visible things an invisible fecundity, a dimmed light, a meek namelessness, a hidden wholeness. This mysterious unity and integrity is wisdom, the mother of us all, "natura naturans." There is in all things an inexhaustible sweetness and purity, a silence that is a fountain of action and joy. It rises up in wordless gentleness, and flows out to me from the unseen roots of all created being.
