A sincere story can be learned from the past.

There is a passage in The Doctrine of the Mean: "The most sincere way can be predicted. If the country wants to prosper, it must be auspicious; If the country is going to die, there must be evil spirits. See the tortoise, move four bodies. A disaster is coming, and a good omen is coming; If you are not good, you must be a prophet. As sincere as God. " This passage actually illustrates the predictable theoretical basis such as turtles. What is the theoretical basis? This is sincere. If people can reach the state of sincerity, they can know in advance. The so-called foresight is actually to predict the future development trend of things. If the country wants to prosper, there must be auspicious signs; When the country is about to die, there must be ubers. The country is like this, so is the development of everything, especially the country is the big end of things, so we only cite the country to illustrate the problem here, just like the heaven and earth in the Book of Changes to illustrate the problem. This kind of auspiciousness and evil spirits can be expressed by turtles or four bodies. Turtle is a method used by the ancients for divination and prediction. In this way, when human disasters or blessings are about to happen, goodness, that is, good conditions, can of course be known in advance; Poor, that is, bad situation, can certainly know in advance. Therefore, people can reach the state of sincerity, just like immortals, they can be enlightened by immortals and have foresight. We often say that sincerity is the spirit and its root is here. So, what is sincerity, and why can people know it in advance?

The Doctrine of the Mean further states: "Only sincerity in the world can make the best use of it. If you can do your best, you can do your best. If you can make full use of human nature, you can create the best things. If we can make the best use of everything, we can praise the teaching of heaven and earth. If you can praise the cultivation of heaven and earth, you can go to heaven and earth. " Honesty is a philosophical concept in The Doctrine of the Mean, which talks about the natural state of people, heaven, earth, nature and other things, and is the true face of things. Therefore, only the sincerity of heaven and earth can create the nature of all things, the nature of man, the nature of creation, the nature of creation, the counselor of the education of heaven and earth, and the interaction with heaven and earth, that is, the integration with heaven and earth, and the harmony with the law of the generation of heaven and earth. If you refer this passage to the article "Uncovering the Mystery of Predicting the Future" I said earlier, everything will be clear naturally.
