Tao Te Ching is the source of China's traditional culture, and it has the same origin as Zhouyi. I ching uses "image number system" to explain the universe and life, while Tao Te Ching uses literal meaning to explain the universe and life. The inappropriate metaphor is that Zhouyi is like describing the laws of the universe with mathematics, which is very accurate, so there are prophecies such as magic numbers in the system of Zhouyi. The Tao Te Ching describes the laws of the universe with words, which is very profound, so people with different attainments will have different understandings when reading the Tao Te Ching.
Because Tao Te Ching is a classic work describing the evolution of the universe, its connotation can be used to guide all fields in the world. Because everything evolved from Tao, and Tao Te Ching is the description of this evolutionary law. Since ancient times, Taoist practitioners have used the Tao Te Ching to guide their practice and restrain themselves. The emperor ruled the world with the Tao Te Ching; The general used the Tao Te Ching to formulate a strategy. . . . . . In a word, Tao is the source of all things, and Tao Te Ching, as a classic work to explain the connotation of Tao, is naturally omnipotent.
But only people with very high moral cultivation can truly understand the connotation and implement it firmly. The nature of ordinary people is blinded by secular desires and difficult to understand. . . . . .
I suggest a friend read the first article "Ancient Naivety" in Huangdi Neijing, which is very wonderful (*-*).
