The Analects, The Doctrine of the Mean
Context: 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.

Martí : Thoughts/Pensamientos (1994)
Context: Happiness exists on earth, and it is won through prudent exercise of reason, knowledge of the harmony of the universe, and constant practice of generosity. He who seeks it elsewhere will not find it for, having drunk from all the glasses of life, he will find satisfaction only in those.
