What is the meaning of "The Meanings of the Middle Kingdom"?

The Meanings of the Mean is an ancient Chinese moral philosophy treatise on the realm of life cultivation, one of the classics of Confucianism, originally the thirty-first book of the Book of Rites, rumored to have been written by Zi Si during the Warring States period.

The content of the book affirms that "Zhongyong" is the highest standard of moral behavior, regards "sincerity" as the essence of the world, believes that "sincerity" is the highest state of life, and puts forward the idea of "learning from the world, learning from the world, learning from the world, learning from the world". He also proposed the learning process and cognitive method of "Learning by erudition, inquiring by scrutiny, thinking by prudence, discerning by clarity, and practicing with certainty".

The theoretical basis of the Middle Way is the unity of heaven and man. Usually people talk about the unity of heaven and man mainly from the philosophical point of view, mostly from the "Mengzi" "to do his heart, know his nature; know his nature, then know the sky" ("to do his heart") to talk about, but ignore the middle way of the unity of heaven and man, and even more so, ignored the real meaning of the unity of heaven and man.

The real meaning of the unity of heaven and man is the unity of sincerity, goodness, to achieve "to the neutral, the status of heaven, the breeding of all things," "only the world's sincerity, to be able to do its nature. If you can fulfill your nature, you can fulfill the nature of man; if you can fulfill the nature of man, you can fulfill the nature of things; if you can fulfill the nature of things, you can praise the fertilization of heaven and earth; if you can praise the fertilization of heaven and earth, you can participate in the world with heaven and earth.
