The Book of Changes should serve the public from the beginning, and it can be used to guide people's production and life in primitive tribal times. For example, going out hunting today depends on whether it rains or not. This is a very simple application.
With the progress of society and the emergence of classes, the Book of Changes has become a tool of class rule. The theory and high-level prediction of the Book of Changes are in the hands of the rulers or serve the ruling class completely. Ordinary people can't reach it, but they have been using it, but they just don't know that they are using the wisdom of the Book of Changes. The so-called Shu Ren doesn't know daily necessities.
Now is the Internet age, and knowledge is exploding. The Book of Changes also conforms to the trend, and anyone can learn from it. This is a good sign. However, the various theories of the Book of Changes are mixed, and some are purely profit-driven, which is not conducive to the development of the Book of Changes.
What I said above is actually nonsense. Now people can't fully understand the Book of Changes. Personally, I think there are several reasons:
First, the time span is too large. What was written in the ancient life style cannot be completely copied to the present. This is mainly manifested in the Book of Changes. Many things recorded in the Book of Changes will not happen in modern society, and the meaning of ancient Chinese characters is very different from that of modern Chinese characters.
Second, few people know predictive mathematics. Predicting numbers is the most important and primitive form of I ching thought. With the passage of time, the prediction of the Book of Changes has become very complicated, and each has a set of complex theories and operational routines, which not everyone can learn in a short time. This is also a reason that restricts the popularization of the Book of Changes.
Third, the limitations of traditional ideas. Nowadays, people think the Book of Changes is superstitious and don't want to know more about it.
Fourth, the research direction is single. The Book of Changes is an encyclopedia that can be used in all walks of life, but now no one knows everything about all industries. As a result, entrepreneurs learn the management philosophy of the Yijing, the Yijing of medicine and the geomantic omen of architecture.
In fact, the Book of Changes is not difficult to understand, because no matter how it is used, its overall thinking will not change, that is, the thinking of Yin and Yang.
Li Luo said so much, my level is limited. I hope I can help you.
