The original text probably means that the avenue is invisible, tangible and intangible, and the natural mystery is endless, which seems to be non-existent. In fact, it has always been there, and the laws of nature rule the world!
We often say that man is inferior to heaven, man is dominated by nature, and everything in the world is dominated by nature. Nature endows us with human body, gives us life and controls our life cycle. We should wake up in the morning, go to bed at night, be young and energetic, get heavier with age, and so on. If you go against nature, you will shorten your life. If you follow nature, you will live a long life.
We always think we are smart, but in fact, our thoughts, feelings, emotions, feelings and understanding are insignificant in the face of "natural temper".
But we can't give up on ourselves because of this. Honesty, trustworthiness, justice and other excellent qualities must continue to adhere to, be a good individual in essence, and take a relaxed and happy walk in our own world.
