Taoism is one of the important schools of ancient philosophy in China, and Taoism is its core concept. Among them, Tao Te Ching is one of the core classics of Taoism, written by Laozi. In the Tao Te Ching, there is a very famous scripture: "Tao can be Tao, but it is extraordinary." This sentence expresses the understanding and pursuit of Taoism.

First, the background of Taoist thought

Taoism originated in China during the Spring and Autumn Period and the Warring States Period. At that time, various schools of thought such as Confucianism, Mohism and Legalism were formed. Taoism is a unique philosophical thought that rose in this era.

Second, the connotation of Tao

In Taoist thought, Tao is the most basic existence in the universe and the root, source and law of all things. Tao itself is nameless, invisible and wordless. It is beyond human understanding and can be said to be unspeakable. Therefore, according to the viewpoint of Tao Te Ching, "Tao can be Tao, but extraordinary."

Third, the interpretation of "Tao can be Tao, extraordinary Tao"

1. Tao cannot be said: Taoism believes that words are limited and Tao transcends the boundaries between words and concepts. The unspeakable significance of Tao is that we can't describe the characteristics and essence of Tao accurately in words.

2. Tao needs experience: According to Taoism, Tao is a practical philosophy. Only through practice and experience can people realize the existence and significance of Tao. Therefore, Tao is not obtained through the interpretation of words or concepts, but is understood through direct experience and practice.

3. Tao is an existence beyond the normal state: there is another sentence in Tao Te Ching: "It is unusual to be famous." This sentence emphasizes the transcendence and unpredictability of Tao. Far from the normal state, it is not bound by language, concepts and regulations.

Fourth, the connotation of "only keeping fresh, full of Kun"

"Only keep the pure qi and be full of Gankun" is a passage in Taoist thought, which emphasizes the importance of pure qi to the world and the relationship between pure qi and Tao. This sentence expresses the Taoist pursuit of pure and natural lifestyle and values.

Clear gas represents pure and impurity-free breath, which is a noble temperament and realm. In the Taoist concept, only by removing all turbidity, impurities and desires and keeping the mind in a clean, selfless and peaceful state can we be connected with the Tao and gain real freedom and happiness.
