What is the logic of divination in the Book of Changes?

The Book of Changes is a wonderful work in China and even the world. Its content is profound and varied. Its value plays a huge role and has far-reaching influence. It is the great creation of our ancestors and the high crystallization of their wisdom. Ancestors' divination is the product of their psychological function that they feel powerless and unable to grasp the consequences of their experiences and actions under natural, social and various pressures, and feel confused and anxious inside, hoping to turn disasters into blessings and eliminate disasters and promote happiness with the help of the revelation of the gods. Or it is difficult for people to make a clear explanation of fate, and some people will try to predict good luck or bad luck with divination. Although it is not known whether the divination of the sixty-four hexagrams in the Book of Changes has magical power, after the perfection of the "three saints", its thinking method is precise and ingenious, which is helpful for thinking, education and inspiration, and indeed has the function of life consultation that cannot be ignored. We can regard it as a correct guide to life behavior, because sixty-four hexagrams are sixty-four questions in life, and three hundred and eighty-four hexagrams are possible situations and the best countermeasures in three hundred and eighty-four situations. Usually, we use sixty-four hexagrams for divination, not to predict good or bad luck, but to seek how to avoid bad luck. Of course, in a sense, this actually means observing the good or bad luck. It is foreseeable that what should be done and what should not be done are fierce. Therefore, it is more appropriate to regard divination as a life consultation activity. In other words, asking divination is asking for advice from the Book of Changes, a life teacher.
