Chapter 43
第四十三章
The softest thing in the world dashes against and overcomes the hardest;
天下之至柔,馳騁天下之至堅(jiān)。
that which has no (substantial) existence enters where there is no crevice.
無有入無間,

I know hereby what advantage belongs to doing nothing (with a purpose).
吾是以知無為之有益。
There are few in the world who attain to the teaching without words, and the advantage arising from non-action.
不言之教,無為之益,天下希及之。
