The manifestation of Virtue

"The skilful philosophers that were in the olden time had a mystic communication with the abysses. They were deep and cannot be known. And whereas they cannot be known, I strain my imagination to picture them. Timid were they, like one fording a stream in winter. Cautious were they, like one who dreads his neighbour. Circumspect were they, like a man from home. Vanishing were they, like ice that is about to melt. Simple were they, like unwrought wood. Vacant were they, like a valley. Dim were they, like muddy water. Who is there that can take the turbid water, and, by stillness, make it gradually clear? Who is there that can take what is at rest, and, by continuous motion, make it gradually alive? Those who keep this Tau desire not fulness. And whereas they are empty, they may wax old, and yet not stand in need of renewing."
