《淮南子·泰族训》
那 道 ，有形的事物都由它产生，它如同万物之父母，与物关系密切；世上吃谷、食气者都受 道 的支配，它如同明君，给予的恩惠实在是多；诸多的聪明人都学习 道 ，它如同良师，给人的知识实在渊博。
夫道，有形者皆生焉，其为亲亦戚矣；享谷食气者皆受焉，其为君亦惠矣；诸有智者皆学焉，其为师亦博矣。
That Dao, all things with form are produced by it. It is like the parents of all things, closely related to things; everyone in the world who eats grains and eats qi is controlled by Dao. It is like an enlightened monarch, giving so much grace; many smart people study Dao. It is like a good teacher, giving so much knowledge.
