"Shuogua Zhuan" says: "Qian is the head, Kun is the abdomen, Zhen is the foot, Xun is the thigh, Kan is the ear, Li is the eye, Gen is the hand, and Dui is the mouth." This refers to the Eight Trigrams diagram.
Bagua is a cosmic illustration that the ancients further scientifically understood their understanding of the universe. Therefore, the Bagua not only contains the laws of the universe, but also reflects the eight natural phenomena in the universe and the thousands of changes.
Bagua symbols accompanied the evolution and evolution of ancient tribal clan society for thousands of years, gradually evolving China from the ancient aquatic race to the farming culture of the Han people.
In the long historical evolution, in order to survive and reproduce, ancient humans used the simplest materialism to unremittingly observe, explore and recognize the vast natural phenomena of the universe, and initially created the innate Bagua. Begin to explore the laws of the time and movement to adapt to human survival and development.
acquired Bagua evolved from the innate Bagua, with clear distinction between spring, summer, autumn and winter, turning clockwise, setting eight festivals in all four seasons, farming in time, harvesting in time, keeping pace with the times, showing that humans' fish hunting from tribes are specially designed for farming life.
Nan Huaijin mentioned in "Miscellaneous Thoughts on the Book of Changes": In terms of application, what we use now is generally a combination of the two - using the "number" of the innate Bagua and the "image" of the acquired Bagua.
"Innate" means that before the universe was formed or before everything was formed, it was still in the initial stage of brewing, that is, the original state and chaotic state before geographical changes. This period is the "innate" state.
The main theme of "Innate Bagua" is about the foundation of the universe and its functions. Innate is the "body", body is the source, body is the Tao, and body is the principle.
"Innate Eight Trigrams", its main content is expressed in "Yi·Shuogua Zhuan": "The heaven and earth are positioned, mountains and lakes are ventilated, thunder and wind are thin, and water and fire are not emitting. The Eight Trigrams are wrong, and the numbers are forward, and those who know the future are reversed, so it is easy to reverse numbers." The order of the diagram is quite simple, but the diagram contains the mysterious orifices of creation between heaven and earth, which can understand the root of mathematics and law.
"Acquired" means that after the universe begins to form or all things in the world are in the stage of generation, movement, change and development, that is, the state of continuous circulation and change after geographical changes. This period is the state of "Acquired".
There is a saying in the Book of Changes: All things come from Zhen, equal to Xun, meet each other in Li, and end up fighting Kun, speaking from Dui, fighting from Qian, working from Kan, and becoming Gen. This is the basic content of "After Heavenly Gossip".
"Acquired Bagua" is based on a separate combination of "innate". Its main purpose is to explain the operation and function of all things in the universe, describe the laws of the generation, change and development of the earth and its material world, and reveal the laws of the action of the movement of the universe's celestial bodies on humans.
The Bagua theory is a very important theory in ancient Chinese philosophy. It is the world view or cosmic view of the world. It summarizes all things in the world into eight types of hexagrams or categories (types). It is an ancient Chinese classification method: "Yi Qian is the image, and the image is the image."
The essence of the Book of Changes is image, and image is image or abstract, and behind the image is concrete things. The theory of gossip marks that humans have reached a high level of understanding of nature, human beings, and society.
