"For the countenance of great virtue, only the Way is to be followed. As a thing, the Way is abstract and elusive; elusive and abstract, there are images in it; abstract and elusive, there is something there. Recondite, hidden, it has vitality therein: that vitality is very real; it has truth therein. From ancient times to now, its name is the undeparting; thereby are seen all beauties. How do I know all beauties are thus? By this."
