The cultivation of the person

"When in the world beauty is recognized to be beautiful, straightway there is ugliness. When in the world goodness is recognized to be good, straightway there is evil. And thus, in like manner, existence and non-existence mutually originate (or suggest) each other; so also difficulty and ease, long and short, high and low, treble and bass, before and after. The sage accordingly confines himself to what is without effort (not demonstrative). He carries on teaching without words; and everything works without hindrance. He produces without holding possession. He acts without presuming on the result. He completes his work and assumes no position for himself. And, since he assumes no position, he never loses any."
