The heart's position in the body is the ruler's position in the state. The nine orifices have their functions, as officials have their assignments. When the heart keeps to its Way, the nine orifices follow principle. When desires and cravings overflow, the eyes cannot see color and the ears cannot hear sound. Therefore it is said: when those above depart from the Way, those below lose their tasks. Do not gallop in place of the horse — let it exhaust its strength. Do not fly in place of the bird — let it wear out its wings. Do not move before things — observe their patterns. The Way is not distant yet difficult to reach — it dwells alongside man yet is hard to grasp. Empty your desires and the spirit will enter its lodging; sweep clean the impurities and the spirit will remain. The formless and shapeless that is called the Way; what transforms and nurtures the myriad things is called virtue; the affairs between ruler and minister, father and son, is called duty; ascending and descending, bowing and yielding, the hierarchy of noble and base, is called propriety; what simplifies things and unifies the Way through execution and prohibition is called law.
