Chapter 27
The skilful traveller leaves no traces of his wheels or footsteps; the skilful speaker says nothing that can be found fault with or blamed; the skilful reckoner uses no tallies; the skilful closer needs no bolts or bars, while to open what he has shut will be impossible; the skilful binder uses no strings or knots, while to unloose what he has bound will be impossible. In the same way the sage is always skilful at saving men, and so he does not cast away any man; he is always skilful at saving things, and so he does not cast away anything. This is called 'Hiding the light of his procedure.' Therefore the man of skill is a master (to be looked up to) by him who has not the skill; and he who has not the skill is the helper of (the reputation of) him who has the skill. If the one did not honour his master, and the other did not rejoice in his helper, an (observer), though intelligent, might greatly err about them. This is called 'The utmost degree of mystery.'
第二十七章
善行，无辙迹①；善言②，无瑕谪③；善数④，不用筹策⑤；善闭，无关楗而不可开⑥；善结，无绳约而不可解⑦。是以圣人常善救人，故无弃人；常善救物，故无弃物。是谓袭明⑧。故善人者，不善人之师；不善人者，善人之资⑨。不贵其师，不爱其资，虽智大迷，是谓要妙⑩。
译文
善于行走的，不会留下辙迹；善于言谈的，不会发生病疵；善于计数的，用不着竹码子；善于关闭的，不用栓梢而使人不能打开；善于捆缚的，不用绳索而使人不能解开。因此，圣人经常挽救人，所以没有被遗弃的人；经常善于物尽其用，所以没有被废弃的物品。这就叫做内藏着的聪明智慧。所以善人可以做为恶人们的老师，不善人可以作为善人的借鉴。不尊重自己的老师，不爱惜他的借鉴作用，虽然自以为聪明，其实是大大的糊涂。这就是精深微妙的道理。
