虚无
原文
希言自然，故飘风不终朝，骤雨不终日。孰为此者？天地。天地尚不能久，而况于人乎？故从事于道者，道者，同于道；德者，同于德；失者，同于失。同于道者，道亦乐得之；同于德者，德亦乐得之；同于失者，失亦乐得之。信不足，焉有不信焉。
王弼注
希言自然。听之不闻名曰希，下章言，道之出言，淡兮其无味也，视之不足见，听之不足闻，然则无味不足听之，言乃是自然之至言也。故飘风不终朝，骤雨不终日。孰为此者？天地。天地尚不能久，而况于人乎？言暴疾美兴不长也。故从事于道者，道者同于道，从事，谓举动，从事于道者也。道以无形无为成济万物，故从事于道者，以无为为君，不言为教，绵绵若存而物得其真，与道同体，故曰同于道。德者同于德，德，少也，少则得，故曰得也。行得则与得同体，故曰，同于得也。失者同于失。失，累多也，累多则失，故曰失也。行失则与失同体，故曰，同于失也。同于道者，道亦乐得之；同于德者，德亦乐得之；同于失者，失亦乐得之。言随行其所，故同而应之。信不足焉，有不信焉。忠信不足于下，焉有不信也。

(Absolute vacancy) Abstaining from speech marks him who is obeying the spontaneity of his nature. A violent wind does not last for a whole morning; a sudden rain does not last for the whole day. To whom is it that these (two) things are owing? To Heaven and Earth. If Heaven and Earth cannot make such (spasmodic) actings last long, how much less can man! Therefore when one is making the Dao his business, those who are also pursuing it, agree with him in it, and those who are making the manifestation of its course their object agree with him in that; while even those who are failing in both these things agree with him where they fail. Hence, those with whom he agrees as to the Dao have the happiness of attaining to it; those with whom he agrees as to its manifestation have the happiness of attaining to it; and those with whom he agrees in their failure have also the happiness of attaining (to the Dao). (But) when there is not faith sufficient (on his part), a want of faith (in him) ensues (on the part of the others).
