《黄帝内经·灵枢·师传》
黄帝说：我听说前辈老师有很多心得秘密，没有记载在书籍里，我想了解它们而将它们保存下来，作为准则加以推广实行，上可以统治百姓，下可以修养自身，使百姓没有疾病，统治者和百姓相互和睦友爱，美德流传后代，使得子孙继承优良传统而无忧，这样的状态流传百世，没有终止之时。
黄帝曰：余闻先师，有所心藏，弗著于方，余愿闻而藏之，则而行之，上以治民，下以治身，使百姓无病，上下和亲，德泽下流，子孙无优，传于后世，无有终时。
The Yellow Emperor said: I have heard that the teaching of our ancient masters contains many good ideas and secrets that are not written down in their books, and I would like to learn about them, and preserve them, to use them as standards, and spread them around, so that above they can be used to rule the people, and below they can be used to cultivate oneself, so that the people will not fall ill, and the rulers and the ruled will live together in harmony and love, their fine virtues handed down to later generations, so that their sons and grandsons will inherit the good traditions and have no worries, such conditions continuing for a hundred generations, and never coming to an end.
