No escape from paradox: Wisdom manifests itself, and is yet hidden. The more it hides, the more it is manifest; and the more it is manifest, the more it is hidden. For God is known when apprehended as unknown, and is heard when we realize that we do not know the sounds of God's voice. The words uttered are words of full silence, and they are bait to draw us into silence. The truths manifested are full of hiddenness, and their function is to hide us, with themselves, in God from whom they proceed. If we hide the precepts of wisdom in our heart -- precepts of humility, meekness, charity, renunciation, faith, prayer -- they themselves will hide us in God. For the values which they give to us, are completely hidden from our eyes. They bring us to the source of a life that is unknown to the natural wisdom of the world, and yet from this source of nature itself proceeds, is nourished, and is sustained.
The acquirement of spiritual wisdom does not necessarily prevent us from making worldly mistakes; but because it develops the qualities that will prevent them, and because it takes to heart the lessons of experience, humbly and receptively, it does reduce the frequency of those mistakes.
