What do you mean by man's law, earth's law, heaven's law and Taoism's nature?

It means: man takes the method from the ground, the ground takes the method from the sky, the sky takes the method from the Tao, and the Tao is purely natural.

Original text:

Chapter 25 of Tao Te Ching

Author Laozi

During the Spring and Autumn Period of the Dynasty

Things were mixed, born in nature, lonely and lonely, independent and unchanging, walking around without danger, which can be the mother of heaven and earth.

I don't know its name. The word "Dao" means "Da". ? Great is death, and death is far away.

it's the opposite from afar. ? The old road is big, big, big, and the king is also big. ? There are four in the domain, and Wang Juyi is one of them.

man practices the land, the land practices the heaven, the heaven practices the Tao, and the Tao is natural.

Translation

There is a mixture of things that existed before the formation of heaven and earth. You can't hear its voice or see its shape. It is silent and empty, independent and eternal without any external force, circulating and never failing, which can be regarded as the foundation of everything.

I don't know its name, so I reluctantly called it Dao, and then I reluctantly named it Da. It is boundless and running endlessly, running endlessly and stretching far away, stretching far away and returning to its original place.

so it is said that there are big, big, big and big people. There are four universes, and people live in one of them. People take the method of land, land takes the method of heaven, heaven takes the method of "Tao", and Tao is purely natural.

Extended information:

Tao Te Ching, a philosophical work of Laozi (Li Er) in the Spring and Autumn Period, also known as the True Classic of Morality, Laozi, Five Thousand Words and Laozi's Five Thousand Articles, is a work of Taoist philosophy before the separation of the pre-Qin philosophers in ancient China.

The Tao Te Ching is divided into two parts. The first part of the original is the Tao Te Ching, and the second part is the Tao Te Ching, which is divided into 81 chapters.

The text of Tao Te Ching takes the philosophical meaning of "morality" as the key line, and discusses the ways of self-cultivation, governing the country, using troops and keeping in good health, but mostly takes politics as the purpose. It is the so-called "sage inside and king outside" and is known as the king of all classics with profound meaning and extensive inclusion.

Tao Te Ching is one of the greatest masterpieces in China's history, which has a profound influence on traditional philosophy, science, politics and religion.

According to the statistics of UNESCO, the Tao Te Ching is a cultural masterpiece that has been translated into foreign languages with the largest number of publications except the Bible.
