Chapter 22 - Doctrine of the Mean

It is only he who is possessed of the most complete sincerity that can exist under heaven, who can give its fun 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.
