Xuan Chu said: "Since what I said represents the general public, it means that most people recognize the facts, why do most people not know the truth that yin and yang are mutually reinforcing and repetitive?" ”

Xiao Tianshu said with a smile: "Yin and Yang are the descriptions of the basic factors hidden behind the laws of nature and the development and change of the laws of nature in ancient Chinese civilization, the driving force behind the birth, development, maturity, decline and extinction of various things, and the core elements that lay the foundation of logical thinking in Chinese civilization. Generally speaking, according to the understanding of Yi Xue's thinking, what it describes is the most basic elements of the universe and their functions, which is one of the basic concepts of Fu Xi Yi. ”

Chu rolled his eyes and said, "I also know what you said that on the earth, the significant manifestation of yin and yang is the influence of the sun and the moon on the earth. This is because the earth's own motion is manifested as the relative motion with the sun and the relative motion with the moon, and the relationship between the two motions is unified on the earth's motion, forming an inseparable comprehensive influence of yin and yang on the research object. There is yin in yang, and there is yang in yin, which cannot be separated. ”

Xiao Tianshu: "Hetu, I'm afraid you don't know, right?" Hehe! Yin and Yang are also the theoretical basis of the root map of Chinese culture - Hetu, Luoshu, and "Fuxi Congenital Sixty-four Hexagram Fangyuan Diagram". To put it simply, in terms of origin, Chinese civilization is based on the basic element of yin and yang and gradually established and developed, after a long period of continuous in-depth understanding of yin and yang, the theory of yin and yang in ancient Chinese philosophy has been formed, and from the perspective of application, a series of yin and yang knowledge covering various fields, including philosophy, natural science, social science, life science, spiritual science and other categories. ”

Xuan Chu smiled: "You really underestimate and forget, why haven't I heard of these, my master is the immortal Lu Dongbin, he is the immortal of the Three Realms, the most well-known among the common people, the existence of Yushu Linfeng, I have followed him for so long, can the master tell me something about the Book of Changes!" ”

Hui Chu said proudly: "Everything has yin and yang, which cannot be separated, yin and yang must be interdependent, and everything contains the characteristics of yin and yang." Yin and Yang, 0 and 1 of the computer binary system, 0 is yin and 1 is yang. There are several groups of yin and yang relationships in the eight trigrams, the yin and yang of Qiankun, the yin and yang of Gendui, the yin and yang of Zhenxun, and the yin and yang of Kanli. Although these belong to the same yin and yang relationship, they are different and cannot be generalized. Specifically, there are the following parts: the yin and yang mutuality relationship of Qiankun, where the mutuality refers to: the two sides exist because of the existence of each other. Generally speaking, it is with the concept of the earth that there is the concept of heaven above the earth. On the other hand, heaven refers to the heaven on earth, and without this heaven there would be no corresponding earth. Heaven exists because of the existence of the earth, and the earth exists because of the existence of the heavens. ”

Xiao Tianshu smiled: "Ah! I didn't think you knew this? ”

Xuan Chu smiled: "What's the matter, I also know that the yin and yang of Gen Dui is the relationship between transformation and education, and the transformation and education here refers to: the ability to generate, conceive, and create new things. The interaction between the two hexagrams will produce and create new things. From the perspective of Fuxi Yi theory, we compare the orientation of the circle map in the "Fuxi Congenital Sixty-four Hexagram Circle Map", Dui Gong is in the southeast, and Gen Palace is in the northwest, which is in line with the geographical environment of this land in China. From the perspective of the Central Plains, the southeast is the sea, the northwest is the plateau, the southeast is the direction of the palace, and the northwest is the direction of the Gen Palace, which is exactly in line with the law revealed in the "Fuxi Congenital Sixty-four Hexagrams", which is why the people bred on the land of China have incomparable creativity, the courage and wisdom to overcome all difficulties, so that the Chinese nation has at least 6,000 years of endless life. It is precisely because of the yin and yang effect of Gendui that there are constantly new discoveries, new inventions, and new creations on the land of China, which can exist and develop forever, constantly adapt to the changes of the times, and stand at the forefront of the tide. These are all tables of chemo-reproductive functions. "People" and "earth" spirits are not vain, it contains rich connotations, and people and the earth will sense each other. ”

He also said: "The yin and yang of Zhenxun have the same root relationship, and the same root here refers to: the same origin, that is, the meaning that both the two hexagrams of Zhenxun originated from the Zhen hexagram. The opposition between yin and yang, here refers to two completely opposite effects. These two opposing effects have a completely different effect on the other party from the outside and the effect on the other party from the inside. It can be seen that the yin and yang properties in Bagua are not exactly the same. When it comes to yin and yang, we can only have the one-sided concept of yin and yang opposites, but we should also pay attention to differential treatment, follow commonalities, and distinguish differences. The use of wonder, in one mind. ”

Lu Dongbin smiled: "A little fur is shown off everywhere, hehe......"

Xiao Tianshu said: "Ancient Chinese philosophers believed that (yin and yang) "two qi [qì] sympathy, the transformation of all things" (Song Dynasty Zhou Dunyi's "Taiji Diagram"), the transformation of all things from the interaction between yin and yang, this philosophical thought originated from the pre-Qin Zhujia, such as "Xunzi Book of Rites" said: "Heaven and earth are harmonious and all things are born, and yin and yang change one after another." ”

He also said: "Heaven and earth sense for the transformation of all things" to point out that yin and yang sympathy is the change and fundamental condition of the transformation of all things, in which "combination", "connection", "induction" and so on all have the meaning of interaction and mutual influence. Therefore, it can be said that the interaction between heaven and earth, yin and yang is the origin of the generation and change of all things.

Yin and yang change

Chu said: "In the natural world of the universe, the law of the formation of things is indeed the same. The yang qi of the sky descends, the yin qi of the earth rises, and the yin and yang qi sympathize and give birth to all things, and form rain and fog, thunder and lightning, rain and dew, sunlight, and air, which are sympathetic to each other, and life forms can be generated. Therefore, if there is no sympathetic movement of yin and yang, there is no nature, and there is no life. It can be seen that the sympathy of yin and yang is the basic condition for the production of life activities. ”

Yin and Yang immediately refers to the existence of two opposing aspects of Yin and Yang in all things or phenomena in the world, such as up and down, heaven and earth, movement and stillness, rise and fall, etc., in which the upper is yang, the lower is yin, the sky is yang, the earth is yin, movement is yang, stillness is yin, ascending belongs to yang, descending belongs to yin. The opposing yin and yang are interdependent, and neither can exist separately from the other. If the top is yang, the bottom is yin, and if there is no top, it doesn't matter if there is down; Hot is yang, cold is yin, and without cold there is no heat. Therefore, it can be said that Yang is dependent on Yin, Yin is dependent on Yang, and each party is the condition of its own existence with the existence of the other side of its opposite, which is the mutual feeling of Yin and Yang.

Xiao Tianshu said: "Hehe, you girl, it's really true, with such a little effort, you will be competitive, tomorrow I will see Master Zu and say, should you be steady and low-key?" ”
