养德
原文
道生之，德畜之，物形之，势成之。是以万物莫不尊道而贵德。道之尊，德之贵，夫莫之命常自然。故道生之，德畜之；长之育之；亭之毒之；养之覆之。生而不有，为而不恃，长而不宰，是谓玄德。
王弼注
道生之，德畜之，物形之，势成之。物生而后畜，畜而后形，形而后成，何由而生？道也；何得而畜？德也；何由而形？物也；何使而成，势也。唯因也，故能无物而不形；唯势也，故能无物而不成。凡物之所以生，功之所以成，皆有所由，有所由焉，则莫不由乎道也。故推而极之，亦至道也。随其所因，故各有称焉。是以万物莫不尊道而贵德。道者，物之所由也。德者，物之所得也。由之乃得，故曰不得不失，尊之则害，不得不贵也。道之尊，德之贵，夫莫之命而常自然。命并作爵。故道生之，德畜之。长之育之，亭之毒之，养之覆之。谓成其实，各得其庇荫，不伤其体矣。生而不有，为而不恃，为而不有。长而不宰。是谓玄德。有德而不知其主也，出乎幽冥，是以谓之玄德也。

(The operation (of the Dao) in nourishing things) All things are produced by the Dao, and nourished by its outflowing operation. They receive their forms according to the nature of each, and are completed according to the circumstances of their condition. Therefore all things without exception honour the Dao, and exalt its outflowing operation. This honouring of the Dao and exalting of its operation is not the result of any ordination, but always a spontaneous tribute. Thus it is that the Dao produces (all things), nourishes them, brings them to their full growth, nurses them, completes them, matures them, maintains them, and overspreads them. It produces them and makes no claim to the possession of them; it carries them through their processes and does not vaunt its ability in doing so; it brings them to maturity and exercises no control over them; - this is called its mysterious operation.
