《明史·列传·卷六十七》
希望陛下想到道理难以穷尽，珍惜时光易逝，考察经书史书，检验自己的思想和行为，终年不间断，那么儒家的学说得到昌明，而且万事都治理得好，岂只上列四件事得到妥善处理呢？ 
愿陛下念义理之难穷，惜日月之易迈，考之经史，验之身心，使终岁无间，则圣学明而万事毕治，岂特四事之举措得其当已耶。
I hope your Majesty can understand that the truth is inexhaustible, that time flies and it should be cherished. I hope that you can examine the classics and historical books, test your own thoughts and behaviors with them, and persevere in this for the rest of your life. Then, the Confucian school will flourish, and everything will be managed well. It will not be limited to the improvement of those four topics.
