What do you think the Book of Changes is? What attitude should we adopt? What is the purpose of our study of the Book of Changes? Do you think I ching is a fortune teller?

The Book of Changes is essentially a book about divination. "Divination" is to predict the development of future events, and The Book of Changes is a book that summarizes the laws and theories of these predictions.

Now many people pay attention to the Book of Changes, mainly the predictive function of the Book of Changes. They are mysterious and curious about its predictive function, and then like and study the Book of Changes.

Modern prediction is to infer the unknown from the known by logical reasoning after field investigation and study of specific things. The prediction of Yi-ology is based on the model of image, number and reason, and imitates concrete things with three ways of thinking: logical thinking, image thinking and inspiration thinking, and makes predictions and judgments on their past, present and future. The language symbols it uses are eight diagrams, sixty-four hexagrams, yin and yang, five elements, heavenly stems, earthly branches, river maps, Luoshu, innate gossip, and the acquired eight diagrams. Generally speaking, there are nothing more than two systems: one is the gossip system, which imitates everything with gossip and sixty-four hexagrams, which can be said to be the symbol system that mainly imitates the universe; The other is the stem-branch system, which imitates everything by the relationship between heaven and earth and their birth, punishment, impact, combination, transformation and harm. It can be said that it is a symbol system that mainly imitates the time of the universe.

The classical primitive prediction represented by Zhouyi mainly imitates everything with eight diagrams and sixty-four hexagrams. In the Han Dynasty, Fang Jing created the divination method of Najia (that is, six hexagrams), which incorporated the system of branches and branches into the sixty-four hexagrams, took the six relatives, six beasts and the world as symbols, and combined the eight diagrams symbol system with the symbols of branches and branches for the first time, greatly enhancing the information, operability, standardization and accuracy of the classic predictions. However, this kind of six-throw copper coins must also include the divination process and divination method of heavenly stems and earthly branches's six relatives and six beasts, which is too cumbersome and rigid. Shao Kangjie, a master of Yi-ology in Song Dynasty, simplified the eight diagrams prediction method and created the plum blossom easy number method. He used time, numbers, sounds, colors and other methods to make divination flexible, broke divination by using the subjectivity, interactivity and variability of divination, and even looked directly at the external reaction, so that the gossip prediction method reached a more rapid, concise, flexible and vivid realm in imitating everything, further embodying the avenue.

However, we can't take the prediction of divination as the fundamental purpose of learning Yi. The purpose of learning Yi-ology should be various, among which the most important ones are: self-cultivation, family harmony and Ming Dow. Because the Book of Changes studies the epistemology and methodology of "a sage can set his ambition tomorrow, set his career in the world, and make doubts in the first place", its purpose is to achieve things, including understanding the life of the universe (analyzing problems) and achieving things (solving problems). Therefore, we should use the philosophy of Yi-ology to guide self-cultivation, improve individual's internal quality and ideological and moral level, improve thinking ability, and constantly improve ourselves, so as to realize "being poor is immune to the world, while being good is helping the world".
