The excellence of the mystery

"Who knoweth the Tao keepeth Silence; he who babbleth knoweth it not. Who knoweth it closeth his mouth and controlleth the Gates of his Breath. He will make his sharpness blunt; he will loosen his complexes; he will tone down his brightness to the general obscurity. This is called the Secret of Harmony. He cannot be insulted either by familiarity or aversion; he is immune to ideas of gain or loss, of honour or disgrace; he is the true man, unequalled under Heaven."
