Taiji is a category used by China's ancient philosophy to explain the origin of the world. The word "Taiji" comes from Zhuangzi: "Tao is above Taiji, not high; Below six poles, not deep; Born, it will not last long; Longer than ancient times, not old. " Too, that is, big; Pole, refers to the end, pole. Extreme things must be reversed, and change will change, so the source of change is Tai Chi.
There are several explanations about the meaning of Tai Chi:
(1) refers to the original vitality of jade wood. Don Ying Da's Yijing Justice: "Tai Chi people, heaven and earth are not divided, and their vitality is mixed." Yi Gan Wei Tai Ji holds that "tangible things are born from the invisible" and puts forward four stages to explain "Yi Tai Chi", including "There are too easy, too early, too early and Tai Su". It's too easy when there is no gas, the gas starts too early, the shape starts too early, and the quality begins with Tai Su. The state in which gas, shape and mass are mixed but not separated is called chaos. Chaos is what the ancients called vitality. Taking Qi as Tai Chi and Object as its original meaning. This view was common in the Han Dynasty, such as Liu Xin's "Taiji Central Vitality"; Wang Chong quoted Yi scholar as saying: "The vitality is not divided, and chaos is one". Zheng Xuan, on the other hand, explained the great pole by "the purity of qi is not divided".
(2) Take the nihilistic noumenon as Tai Chi. For example, Wang Bi explained that "the number of big swallows is not used" and said that "the way to use without using is not to count, but to count, which is also the Tai Chi of four foreigners." Taking "one" as Tai Chi, I think this "one" is not a number, but "nothing", which is the basis for the formation of forty-nine strategic numbers. Han annotation "Easy to have Tai Chi, give birth to two instruments" said: "A husband must never start, so Tai Chi gives birth to two instruments."
(3) Forty-nine numbers of Dayan are not divided into Tai Chi. Cui Jing said, "Forty-nine numbers are combined but not divided, just like Tai Chi. Today is split in two, just like two musical instruments. Divide them into four numbers. One strategy at a time, so four strategies are like four times. " (Li Dingzuo's Book of Changes, according to Huang Yishu's textual research) Cui Jing's exposition on Dayan number and his Taiji theory say that one is not regarded as an empty entity, and forty-nine numbers are not divided into extremes, and gossip is contained in Dayan number. This view is of great significance in the history of philosophy of Yi-ology, and provides a method for Yi Song to transform Han Yi's cosmogenesis theory into ontology.
(4) Yin and Yang mixed regardless of Tai Chi. Zhou Dunyi's Illustration of Tai Chi: "Infinity and Tai Chi, Tai Chi moves and produces Yang, while moving and static, static and dynamic, dynamic and static, are fundamental to each other, and Yin and Yang are separated. The two instruments are upright. " After Zhou Dunyi, the interpretation of Taiji was divided into three schools.
One, represented by Shao Yong, is called polar multiplier. It is pointed out that "Tai Chi is also one, and if you don't move, you will have two, and God is also"; Explain that Tai Chi gives birth to two devices, one of which is parity. He believes that "the heart is big" in man and "Tao is Tai Chi" in heaven and earth.
