9. 故脩身治國也，要莫大於節欲。傳曰：「欲不可縱。」歷觀有家有國，其得之也，莫不階於儉約；其失之也，莫不由於奢侈。儉者節欲，奢者放情。放情者危，節欲者安。（卷四十七 政要論）
9. Thus, to cultivate oneself in order to rule a country, nothing can be more significant than to restrain one’s desires. The book of Li Ji said: “Don’t give in to desires.”We have seen rulers and senior ministers of the past and present had achieved success through hard work and lived frugally, and that those who failed did so were extravagant and wasteful. Frugal people will restrain their desires but spendthrifts will let their desires run free. Self-gratification will endanger one’s life while moderation will keep one safe.
