What philosophy of life has I ching taught us?

The Book of Changes summarized by Duke Zhou is extensive and profound, which is the origin of China's philosophy. However, I also heard that the study of the Book of Changes is easy to make people possessed and enter the misunderstanding of believing in heaven and earth and divination, so I dare not dabble in it easily. After reading the Book of Changes, I was deeply impressed by the rich philosophy of life contained in the Book of Changes. The first is the view of "harmony between man and nature". The Book of Changes says that "Tai Chi gives birth to two instruments, two instruments give birth to four images, and four images give birth to gossip", and that "two, two, three and three give birth to everything". This "three" is "heaven, man and earth". We should say "heaven and earth are one", but for the sake of brevity, we are used to saying "heaven and man are one". Originally, the Book of Changes was based on the theory of yin and yang, with "heaven" as yang and "earth" as yin, but a "person" should be added in the middle. The so-called "heaven" is changeable and "earth" is not, but being caught in the middle is the most uncomfortable, unchanged and unchanged. The original structural analysis of the word "person" is two people, a man and a woman, who depend on each other and support each other. The so-called "people" should stand high, with a sky above their heads to support masculinity. Keep your feet firmly on the ground and put away your feminine side. Therefore, it is really difficult to be a person, and it is even more difficult to be a more active person. The second is the view that "Yin and Yang support each other and transform each other". As early as the Book of Changes, our ancestors expounded the view that "the world is developing and changing", such as "if you don't come to Thailand, you will be extremely sad" and many other statements. Yin and Yang are relative, which does not mean that something must be Yang or Yin. But Yin and Yang are not antagonistic, and they should achieve a harmonious balance. For example, we call the sky Yang and the earth Yin, but we can't decide which is more important. Heaven and earth are interdependent and indispensable. The weather is changeable and time-varying, while the land changes little and is stable. It is precisely because of the stability of the earth that the changes in the sky have been curbed. The earth has always been silent, unknown and willing to pay, so God always listens to the earth and is always bound by its gravity. Imagine, if one day the earth chatters endlessly and wants to compete with heaven, then the whole world will be in chaos. This reminds us of the relationship between husband and wife in the family. Married men and women should learn more about the Book of Changes, especially as wives. If we can learn more from the Book of Changes, the whole family and even the world will be harmonious.
