Turning back

"Knowing man and staying woman, be the riverbed of the world. Being the world’s riverbed of eternal unfailing power is to go back again to be newborn. Knowing light and staying dark, be a pattern to the world. Being the world’s pattern of eternal unerring power is to go back again to boundlessness. Knowing glory and staying modest, be the valley of the world. Being the world’s valley of eternal inexhaustible power is to go back again to the natural. Natural wood is cut up and made into useful things. Wise souls are used to make into leaders. Just so, a great carving is done without cutting."
