Anyone who interferes in it will fail, and who tries to keep it will lost it.
For things may lead or follow,
blow high or low, be strong or weak, loaded or unloaded.
So the sage will not go to excess,
to extravagance and to extreme。
利己，满足自己私欲干点什么，都不会成功。
应该以利他之心，摒弃那些过度的，夸大的，极端的行为，（因为万事万物总是不断转化的）就可以畅万物之情而适万物之性，实现大治。
