Only the sincerity in the world can do its best, which can make the best of human nature, and can make the best of things, which can praise the cultivation of heaven and earth, and can participate in it.
Translation
Only those who are sincere in the world can give full play to their own nature; If you can give full play to your own nature, you can give full play to human nature; If we can give full play to human nature, we can give full play to the nature of all things, and we can sponsor heaven and earth to educate all things; If you can sponsor heaven and earth to educate everything, you can stand side by side with heaven and earth.

The core cultivation idea of Confucianism is "harmony between man and nature". The universe of this day and the universe of people's hearts are one universe, and the truth of the universe is the truth of people's hearts, and the truth of people's hearts is the truth of the universe.
However, there are also great differences in the path of enlightenment, and there is a distinction between Zhu Xi's "reason" and Lu Jiuyuan's "heart". Lu Jiuyuan's philosophy of mind is Wang Yangming's philosophy of mind, which is another story, so let's not mention it for the time being.
In a word, many things will be much simpler and the truth will be much clearer if we go to the counselor and the people with sincere attitude. The natural truth and the sage's truth are very simple, but we have been blindfolded.
