原文
善行无辙迹，善言无瑕讁；善数不用筹策；善闭无关楗而不可开，善结无绳约而不可解。是以圣人常善救人，故无弃人；常善救物，故无弃物。是谓袭明。故善人者，不善人之师；不善人者，善人之资。不贵其师，不爱其资，虽智大迷，是谓要妙。
王弼注
善行无辙迹，顺自然而行，不造不始，故物得至而无辙迹也。善言无瑕讁；顺物之性，不别不析，故无瑕讁可得其门也。善数不用筹策；因物之数不假形也。善闭无关楗而不可开，善结无绳约而不可解。因物自然，不设不施，故不用关楗绳约而不可开解也。此五者皆言不造不施，因物之性，不以形制物也。是以圣人常善救人，故无弃人；圣人不立形名以检于物，不造进向以殊弃不肖，辅万物之自然而不为始，故曰无弃人也。不尚贤能，则民不争，不贵难得之货，则民不为盗，不见可欲，则民心不乱。常使民心无欲无惑，则无弃人矣。常善救物，故无弃物，是谓袭明。故善人者，不善人之师；举善以师不善，故谓之师矣。不善人者，善人之资。资，取也。善人以善齐不善，以善弃不善，故不善人善人之所取也。不贵其师，不爱其资，虽智大迷，虽有其智，自任其智，不因物，于其道必失。故曰，虽智大迷。是谓要妙。
英文 · James Legge
(Dexterity in using the Dao) 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.'
