My description of wisdom has nothing to do with benevolence and righteousness, it is to do with being wise in one's own virtue, nothing more. My description of being has nothing to do with benevolence and righteousness, it is that one should be led by one's innate nature, nothing more.

Right is not right; so is not so. If right were really right it would differ so clearly from not right that there would be no need for argument. If so were really so, it would differ so clearly from not so that there would be no need for argument.

Tao is obscured when men understand only one pair of opposites, or concentrate only on a partial aspect of being. Then clear expression also becomes muddled by mere wordplay, affirming this one aspect and denying all the rest. The pivot of Tao passes through the center where all affirmations and denials converge. He who grasps the pivot is at the still-point from which all movements and oppositions can be seen in their right relationship... Abandoning all thought of imposing a limit or taking sides, he rests in direct intuition.

Study is to study what cannot be studied. Undertaking means undertaking what cannot be undertaken. Philosophizing is to philosophize about what cannot be philosophized about. Knowing that knowing is unknowable is true perfection.

Those who realise their folly are not true fools.

When deeds and words are in accord, the whole world is transformed.
