The Short of It:
Non-action is the best teacher, yet few can teach it.
43. Universal Use.
The weakest things in the world will gallop over the strongest. The non-existent enters into (all things) without any crevice (can penetrate the impenetrable). And I by this understand how useful non-action is. Silent teaching, passive usefulness, -few in the world attain to this.
43. ‘ The Universal Use.’
43.1 The softest thing in the world dashes against and overcomes the hardest; that which has no (substantial) existence enters where there is no crevice. I know hereby what advantage belongs to doing nothing (with a purpose).
43.2 There are few in the world who attain to the teaching without words, and the advantage arising from non-action.
43. Its Universal Application.
43.1 The world’s weakest overcomes the world’s hardest.
43.2 Non-existence enters into the impenetrable.
43.3 Thereby I comprehend of non-assertion the advantage. There are few in the world who obtain of non-assertion the advantage and of silence the lessons.
