The Book of Changes is one of the four books and five classics of Confucianism. According to the documents of China Junyou Association, it is said that when Qin Shihuang burned books to bury Confucianism, Li Si was spared because he included Zhouyi in the book of medical divination. Later, people in all previous dynasties studied Zhouyi, including Fang Jing and Zheng Xuan in Han Dynasty, Wang Bi in Wei and Jin Dynasties, Lu Deming, Li Dingzuo and Kong in Tang Dynasty, Shao Yong, Cheng Yi and Zhu in Song Dynasty.
According to documents, Yi Tu's research rose in the Song Dynasty, such as the famous river map, Luo Shu, congenital map, transit map and left sky map. Sixteen pictures after the wind. Pornographic pictures in the room, artistic pictures. The map of the day after tomorrow, the map of Taiji (including the cake pattern of Yin and Yang fish) and the map of Dragon Eight Diagrams are not available in the original book of changes, but were added by later generations according to their own understanding of the book of changes.
The Yi-ology after Tang and Song Dynasties should be said to have established another "three changes" theory. This new concept of "three changes" is also the three main points to explain the connotation of "reason, image and number" in the Book of Changes after Qin and Han Dynasties and even since modern times.
If we use the modern concept, "rationality" is similar to the category of philosophical thought. It is the principle of exploring the metaphysical, changing and unchanging life of the universe. "Image" is the principle of seeking its change from all phenomena in the real world.
"Number" is a mathematical theory formed from the phenomenon world. This paper deduces its changing process in detail and knows the cause and effect of people and everything from quotations. On the contrary, we can also understand the primitive instinct of metaphysics through mathematical induction.
Combining these three meanings, we can see that the theory of "Yi" is philosophical. The study of "image" and "number" is scientific.
In a word, a complete Yi-ology must reach the philosophical level on the scientific basis of "image" and "number". It does not belong to pure ideological philosophy, but infers everything by analogy based on the concepts of mind and consciousness. The universe is boundless and unpredictable. Opportunities in life are varied. Differentiation and correction of "principle, image and technique" in the comprehensive study of Zhouyi.
The Book of Rites mentions the purpose of the Book of Changes, saying: "Pure and subtle, the teaching of the Book of Changes is also." The so-called "quiet" connotation has the function of scientific and thorough debate at the same time. However, if you don't enter the realm of Yi-ology from the cultivation of meditation, you will go astray and fall into evil spirits.
Therefore, in Jingtiao, the deviation of Yi-ology is likely to be "making people thieves". He made a unique study: "From the beginning of the two hexagrams of Ganzhi and Kunzhi, they overlapped and spread by-pass, and at first they evolved from gossip to sixty-four hexagrams.
Following this different level of deduction and promotion, there will be countless, infinite and "subtle". If we sum up the internal interaction of the hexagrams, we can understand the contents of the sixty-four hexagrams, only specialty, Jing, family, returning to the United States and gradually? Interpretation of sixteen hexagrams by Ji Ji and others. In the internal interaction of the sixty-four hexagrams, these sixteen hexagrams appear four times each.
From the sixteen hexagrams, we can find their internal interaction. There are only four hexagrams, namely, Gan, Kun, Bi, Ji and Wei, and each hexagram has appeared sixteen times. By analogy, we can know that all special reasons or personnel outside the universe are ever-changing, except for the non-essential functions of dryness, Kun, Kan and Li, which represent yin and yang, and the concept of good or ill luck is only composed of two phenomena [Ji Ji].
From this, you can understand the perfect and true state of Yin and Yang before the sky is divided, you can fully understand the spirit of the Book of Changes [pure and subtle], and you can grasp the wonderful use of complacency.
