The course (of duty), virtue, benevolence, and righteousness cannot be fully carried out without the rules of propriety; nor are training and oral lessons for the rectification of manners complete; nor can the clearing up of quarrels and discriminating in disputes be accomplished; nor can (the duties between) ruler and minister, high and low, father and son, elder brother and younger, be determined; nor can students for office and (other) learners, in serving their masters, have an attachment for them; nor can majesty and dignity be shown in assigning the different places at court, in the government of the armies, and in discharging the duties of office so as to secure the operation of the laws; nor can there be the (proper) sincerity and gravity in presenting the offerings to spiritual Beings on occasions of supplication, thanksgiving, and the various sacrifices. Therefore the superior man is respectful and reverent, assiduous in his duties and not going beyond them, retiring and yielding - thus illustrating (the principle of) propriety.

It is only he who is possessed of the most complete sincerity that can exist under heaven, who can give its full development to his nature. Able to give its full development to his own nature, he can do the same to the nature of other men. Able to give its full development to the nature of other men, he can give their full development to the natures of animals and things. Able to give their full development to the natures of creatures and things, he can assist the transforming and nourishing powers of Heaven and Earth. Able to assist the transforming and nourishing powers of Heaven and Earth, he may with Heaven and Earth form a ternion.
