原文
天下皆知美之为美，斯恶已。皆知善之为善，斯不善已。故有无相生，难易相成，长短相较，高下相倾，音声相和，前后相随。是以圣人处无为之事，行不言之教；万物作焉而不辞，生而不有。为而不恃，功成而弗居。夫唯弗居，是以不去。
王弼注
天下皆知美之为美，斯恶已。皆知善之为善，斯不善已。故有无相生，难易相成，长短相较，高下相倾，音声相和，前后相随。美者，人心之所乐进也；恶者，人心之所恶疾也。美恶，犹喜怒也；善不善，犹是非也。喜怒同根，是非同门，故不可得偏举也，此六者皆陈自然不可偏举之明数也。是以圣人处无为之事，自然已足，为则败也。行不言之教；万物作焉而不辞，生而不有，为而不恃，智慧自备，为则伪也。功成而弗居。因物而用，功自彼成，故不居也。夫唯弗居，是以不去。使功在己，则功不可久也。
英文 · James Legge
(The nourishment of the person) All in the world know the beauty of the beautiful, and in doing this they have (the idea of) what ugliness is; they all know the skill of the skilful, and in doing this they have (the idea of) what the want of skill is. So it is that existence and non-existence give birth the one to (the idea of) the other; that difficulty and ease produce the one (the idea of) the other; that length and shortness fashion out the one the figure of the other; that (the ideas of) height and lowness arise from the contrast of the one with the other; that the musical notes and tones become harmonious through the relation of one with another; and that being before and behind give the idea of one following another. Therefore the sage manages affairs without doing anything, and conveys his instructions without the use of speech. All things spring up, and there is not one which declines to show itself; they grow, and there is no claim made for their ownership; they go through their processes, and there is no expectation (of a reward for the results). The work is accomplished, and there is no resting in it (as an achievement). The work is done, but how no one can see; 'Tis this that makes the power not cease to be.
