玄符
原文
含德之厚，比于赤子。蜂虿虺蛇不螫，猛兽不据，攫鸟不搏。骨弱筋柔而握固。未知牝牡之合而全作，精之至也。终日号而不嗄，和之至也。知和曰常，知常曰明，益生曰祥。心使气曰强。物壮则老，谓之不道，不道早已。
王弼注
含德之厚，比于赤子。蜂虿虺蛇不螫，猛兽不据，攫鸟不搏。赤子无求无欲，不犯众物，故毒虫之物无犯之人也。舍德之厚者，不犯于物，故无物以损其全也。骨弱筋柔而握固。以柔弱之故，故握能周固。未知牝牡之合而全作，作，长也。无物以损其身，故能全长也。言含德之厚者，无物可以损其德，渝其真，柔弱不争而不摧折者，皆若此也。精之至也。终日号而不嗄，无争欲之心，故终日出声而不嗄也。和之至也。知和曰常，物以和为常，故知和则得常也。知常曰明。不皦不昧，不温不凉，此常也。无形不可得而见，曰明也。益生曰祥。生不可益，益之则夭也。心使气曰强。心宜无有，使气则强。物壮则老，谓之不道，不道早已。
英文 · James Legge
(The mysterious charm) He who has in himself abundantly the attributes (of the Dao) is like an infant. Poisonous insects will not sting him; fierce beasts will not seize him; birds of prey will not strike him. (The infant's) bones are weak and its sinews soft, but yet its grasp is firm. It knows not yet the union of male and female, and yet its virile member may be excited; - showing the perfection of its physical essence. All day long it will cry without its throat becoming hoarse; - showing the harmony (in its constitution). To him by whom this harmony is known, (The secret of) the unchanging (Dao) is shown, And in the knowledge wisdom finds its throne. All life-increasing arts to evil turn; Where the mind makes the vital breath to burn, (False) is the strength, (and o'er it we should mourn.) When things have become strong, they (then) become old, which may be said to be contrary to the Dao. Whatever is contrary to the Dao soon ends.
