《礼记·中庸》
只有天下最真诚的人才能充分发挥天赋的本性，能发挥天赋的本性才能发挥所有人的本性，能发挥所有人的本性才能充分发挥事物的本性，能够发挥事物的本性才能帮助天地养育万物，可以帮助天地养育万物，才可以与天地并列。
唯天下至诚，为能尽其性；能尽其性，则能尽人之性；能尽人之性，则能尽物之性；能尽物之性，则可以赞天地之化育；可以赞天地之化育，则可以与天地参矣。
The most sincere people in the world are the only ones who can truly express their own nature. Only by expressing your own nature can you express the nature of all human beings, and only by expressing the nature of all human beings can you truly express the nature of things. Only by expressing the nature of things can you help the universe to support all living things. Only by helping the universe to support all living things can you exist on equal terms with the universe.
