Tao Te Ching: Chapter 23
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 Tao 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 Tao 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 Tao). (But) when there is not faith sufficient (on his part), a want of faith (in him) ensues (on the part of the others).
He who stands on his tiptoes does not stand firm; he who stretches his legs does not walk (easily). (So), he who displays himself does not shine; he who asserts his own views is not distinguished; he who vaunts himself does not find his merit acknowledged; he who is self- conceited has no superiority allowed to him. Such conditions, viewed from the standpoint of the Tao, are like remnants of food, or a tumour on the body, which all dislike. Hence those who pursue (the course) of the Tao do not adopt and allow them.
