Five elements and Heluo.

All the friends of Xueyi know the number of five elements, and they all know that the number of five elements is derived from the river map. As the original theories of Yi-ology, Hetu and Luoshu are related to almost all the basic theories of Yi-ology, and determining the number of generations of the five elements is one of them. Determination of the five-element attribute of a number generated by five elements. The specific content is: 1, 6 is water, 2, 7 is fire, 3, 8 is wood, 4, 9 is gold, 5, 10 is earth. Where 1, 2, 3, 4, 5 is a number, and 6, 7, 8, 9, 10 is a number. According to the Book of Changes, it is: "There is water by nature, and the land is 60%; Fire is second, 70% a day; There are three trees in the sky, 80% of the land; The land is rich in gold, 90% in the sky and 100% in the sky. " The reason why this generation number of the five elements is determined from the river map is because we only need to observe the structure of the river map. In the river chart, the north is the number 1 and 6, and the five elements in the north belong to water, so the number of water is determined as 1 and 6. Similarly, in the river chart, the numbers 2 and 7 are in the south and the fire number is in the south, so the fire number is determined to be 2 and 7. In the river map, the number of trees in the east is 3 and 8, and the number of trees in the east is 5, so the number of trees is 3 and 8. In the river chart, the western numbers are 4 and 9, and the western number is 5, so the amount of gold is determined to be 4 and 9. The middle number of the river chart is 5, 10, and the middle number is soil, so the number of soil is 5, 10. This is the principle of the five elements. However, this is only a theoretical expression of the law. There is still a fundamental problem to be solved in determining the number of five elements generated by river charts, that is, what is the legal basis for this corresponding relationship between five elements and numbers? Why do the numbers 1 and 6 in the river map have to be in the north? As far as the mathematical model is concerned, this determination is unreasonable. If the whole river map is rotated by 90,180, 270, the river map is still a river map. As mathematical models, these rotation diagrams have the same meaning. But at this time, the positions of 1 and 6 in the river map are in the east, south and west respectively. In this way, the five elements corresponding to the numbers 1 and 6 in the river map can be any one of water, wood, fire and gold, but not necessarily water. The same is true of other five elements. You can compare the rotation of the river chart by yourself. You can see that except for the number 5 and 10, which are fixed in the center and determined as soil, other numbers will change their positions with the rotation of the graph, so the corresponding five lines are uncertain. Rotating at different angles will correspond to different five elements. Therefore, it is not a simple mathematical model to determine the number of generations of the five elements according to the river map. This correspondence between five elements and numbers has a premise: the graph of river map can not rotate and move. 1, 6 must be in the north, 2,7 must be in the south, and so on. In fact, the river chart cannot be rotated and moved, and all the numbers are fixed in their own positions. Why? Because the river map is not a simple mathematical model, but a model that uses numbers to represent natural phenomena. This is its legal basis, and it is the foundation of combining the energy of river map with the principle of Yi-ology. We still use the previous method to solve the legal basis of the river map, which is also called the pre-Tianhe map, so the river map represents the cyclical rhythm of "heaven" and time. Overlapping the river map with the circular Tai Chi map, we can also see the secrets contained in it. Through the combination and comparison of these two pictures, we can clearly see the common ground among them. Connect the white dots representing yang and the black dots representing yin in the river chart with lines, and you can see a four-image cycle diagram represented by numbers. The numbers 5 and 10 representing the soil in the center of the river map refer to the earth itself, and other numbers show the vortex structure map of the yin-yang cycle. Odd white dots 1, 3, 7, 9 representing Yang are connected together, which is equivalent to the pattern of Yang instrument in the four-elephant cycle diagram, and like the Yang instrument in the four-elephant cycle diagram, it starts from the northern winter solstice solar terms, is born in the shade, and the southern summer solstice solar terms are strong and appear outside, while the western autumn equinox solar terms decline. Even-numbered black dots 2, 4, 6 and 8 representing Yin are connected together, which is equivalent to the pattern of Yin instrument in the four-image cycle diagram. Like Yin instrument in the four-image cycle diagram, it starts from the solar terms from summer to the sun in the south, and is born in the sun. The solar terms from winter to the sun in the north are strong and appear outside, and the solar terms in the eastern vernal equinox decline. In this way, yin and yang interact endlessly, which is completely consistent with the four-image cycle diagram in form and essence. The only difference is that the river chart is a graph composed of 10 numbers to express this cycle law. The perfect correspondence between the four-image cycle diagram and the river diagram is a very important principle and the legal basis for the establishment of the river diagram. The form of Hutuluo is simple, but there are profound changes in it. Fundamentally speaking, the unity of the two mathematical models of Heluo and the principle of Yi-ology is based on the perfect correspondence between the four-image cycle and the river chart cycle. Anyone who learns Yi must first understand the principles of Chu River Map and Luoshu, and to understand the principles of He River Map and Luoshu, he must first understand the consistency of the cycle of He River Map and Four Elephants. Why do you say that? Because this correspondence between the river chart and the four-image cycle chart is the theoretical basis for determining the position of each number in the river chart, that is, the most basic principle for determining the number of five elements. Let's review the contents of the previous four images and five elements: the four images are divided into congenital four images and acquired four images. The congenital four elephants are based on the four seasons of spring, summer and autumn, and the acquired four elephants are based on the four seasons of cold, heat and humidity. The combination of congenital four images and acquired four images forms the concept of five elements, which is a four-dimensional space-time concept including spatial climate change and temporal and seasonal change. According to the climate distribution in China, it is determined that the north of the five elements is water and the time is winter. East is wood, time is spring; The south is a fire, and it is summer; The west is golden, and the time is autumn; The center is the earth, and the time is four seasons. According to this principle, there is a four-image cycle diagram, in which water is north, winter is winter, and the winter solstice is the beginning of yang, and the odd number in the number represents yang, and the number 1 is the beginning of yang, so the position of 1 in the river chart can only be determined within the north, and the north is the direction of water, so the five lines of the number 1 can only be determined as water accordingly. According to the pattern of Hetu Yangyi 1, 3, 7 and 9, other positive numbers are distributed in four directions in a progressive manner, so they all have corresponding five-element attributes. Fire is in the south, that is, summer, and the summer solstice is born in the middle, and the even number in the number represents yin, and the number 2 is the beginning of yin, so the position of 2 in the river map can only be determined in the south, and the five elements are also determined as fire. Other yin numbers are progressively distributed in four directions according to the pattern of Yin meters 2, 4, 6 and 8 in the river map, so they all have corresponding five-element attributes. In addition, the central soil number representing the earth is 5, 10. Finally, the generation number of the five elements was established. The determination of the correspondence between five elements and numbers is of great significance to Yi-ology, because with this correspondence, the Yi-ology system has a mathematical foundation and a unique mathematical model has been established. The four methods of Zhong Yi: the "number" of image, number, reason and occupation refers to this mathematical model. At the same time, this combination also gives the original dull numbers a sense of time and space. With this combination, numbers are no longer a single number. Instead, it is unified with the Yi-ology theories such as Five Elements and Eight Diagrams, and has a corresponding position in the unique space-time pattern of Yi-ology such as orientation and solar terms, thus integrating the mathematical system with the prediction system. Various predictive sciences used to be called astrology. I hope my answer can help you! Please adopt it, thank you!
