What is "harmony between man and nature"?

Heaven, earth and man are "three talents" and an organic whole. Lu Chunqiu's Lust says that "man is the same as heaven and earth". Man can ascend to heaven, imitating heaven and earth. The weather moves and the earth responds, the earth is pneumatic and the weather follows, and the weather moves and people stop. Therefore, where there is justice, there is geography, and heaven pushes to clarify personnel, that is, "heaven and man are one."
