This shows that Taiji "split into two" three times, forming the eight diagrams. Gossip was unknown at first, that is, Lao Tzu said "the beginning of the unknown world", and later became famous as follows:
Then based on the "eight", it is divided into two or three times, that is, from sixteen to thirty-two and then to sixty-four. In this way, gossip formed sixty-four hexagrams. Therefore, "one divides into two" is deeply rooted in China's philosophy and has a long history. Easy to have Tai Chi, giving birth to heaven and earth, giving birth to everything. Heaven and earth are the foundation of all things, and lightning, geomantic omen and volcanic rocks are all its derivatives, which are the products of dichotomy and contradiction between yin and yang.
For example, the auspicious divination (@) means water (yin) and fire (yang), and the upper and lower divinations constitute a pair of contradictions. Another example is guài iê (@), which means that Ze is in heaven. Originally, Ze was not in contradiction with the sky, but only with the mountains. But divination shows that there is lustre in the sky, which contradicts the actual situation and means that it is abnormal. Therefore, warnings such as "unfavorable", "invincible" and "fierce to the end" are repeatedly issued in this divination.
The contradiction between yin and yang in Zhouyi is mainly reflected in the connection. On cohesion, there is a saying that "the combination of rigidity and softness can bring about changes" and "one yin and one yang is the way". In other words, the interaction of opposites such as rigidity and softness of Yin and Yang is the root of all movement changes. The meaning of heaven is "day after month, day after month, the sun and the moon push each other." It's summer when it's cold, it's cold when it's summer, and it's old when it's cold. " This means that the sun and the moon alternate, and cold and heat push each other, so that the world can be bright and everything can be created. These viewpoints all reflect the laws of the movement of the sun and the moon and the change of one cold and one summer in nature. "On Cohesion" also said: "It is easy to have Tai Chi. Is to give birth to two instruments, two instruments give birth to four elephants, and four elephants give birth to gossip. Gossip determines good or bad luck, and good or bad luck leads to great cause. " There is Tai Chi here. Tai Chi became a natural thing before Yin and Yang. The concept of "thing" or "substance" is customarily called "thing" in Chinese. Therefore, "Yi" also has a material meaning, and it also contains the philosophical thought of harmony between Yin and Yang (harmony at both ends and contradiction). This is essentially the same as the "Tao" mentioned by Laozi and Zhuangzi, that is, "Yi" and "Tao" give birth to all things in the world.
So, what is human nature?
The basic idea of Zhouyi is to meet the needs of heaven and man. Both heaven and man are easy to dominate. For human nature, Zhouyi uses men and women to explain yin and yang, heaven and earth, saying: "Dry, yang is the spirit; Kun, the matter of yin is also. The combination of yin and yang, rigidity and softness, is written by the body of heaven and earth to communicate the virtues of the gods. " ("under the copula") Therefore, "dry, the sky is also, so it is called the father; Kun, the land is also, so it is called mother. " ("Shuo gua")
The Book of Changes summarizes the experience of human beings in how to solve contradictions and adjust various relationships.
The first is "home". "Family Gua" says: "Home, women are inside, men are outside. Men and women are different, and the meaning of heaven and earth is also ... the family is right, and the world is fixed. "
The second is "the way to keep the monarch." In Cohesion, it is emphasized that you should keep your own way. It is pointed out that "heaven and earth are great virtues, born every day, and the sage Dabao is in the position of heaven." Why did you keep your position? Why does Ren gather people? Japanese wealth. Financial management is right, and people are forbidden to do wrong things, and they are justified. "Moreover, the most important way to govern the country is not one country and two monarchs:" Yang, one monarch and two people, the way of a gentleman; "Yin, two kings and one person, the way of villains."
The third is to keep secrets. It is pointed out in the copula: "If you are not close, you will lose your position; If you don't keep a secret, you will lose your virginity. If a few things are not kept secret, it will harm people. " Only secrecy can keep the throne, otherwise it will be dangerous.
Fourth, we can be rigid and flexible, and we can advance and retreat. "Dried Melon" says: "Heaven is healthy, and gentlemen are constantly striving for self-improvement." Be strong, but not loud. Because "if you speak loudly, you will know and then you will not retreat, you will know to live but not to die, and you will know to lose but not to lose." Therefore, "those who know how to advance and retreat without losing their integrity are saints." Only a saint can be flexible and be prepared for danger in times of peace. These are all ways for a gentleman to protect himself. Therefore, these wonderful moves in the Book of Changes are valuable experiences in protecting our health, our homeland, our country and the world. It is really "easy, not easy" to understand and do!
