What does the Taiji diagram in the I Ching symbolize?

Symbolizing yin and yang and the mutual birth of all things

The two colors, black and white, represent the two sides of yin and yang, the two parts of heaven and earth; the boundary between the black and white sides is the human part that divides the yin and yang realms of heaven and earth. The black dot in the white indicates that there is a yin in the yang, and the white dot in the black square indicates that there is a yang in the yin. The Taiji diagram is an important picture for the study of the principles of Zhouyi.

Tai has the meaning of to; the extreme has the meaning of limit, that is, to the limit, there is no match. It includes both the principle of extremity and the limit of space-time, which is the largest and smallest, and it can be bigger than any amount but not beyond the circle. Can be greater than any amount and can not exceed the circumference and space, can also be less than any amount and not equal to zero or nothing, the above is the meaning of the word Taiji.

The so-called Tao gave birth to one, a life of two, two gave birth to three, three gave birth to everything; that is, no pole gives birth to Taiji, Taiji gives birth to the two instruments, yin and yang merge and give birth to all things.

Nature is also so, yin and yang, summer and cold, the growth of the four times of the growth of the collection, that is, the growth of the law of all things, all contain yin and yang and five elements. On the human part of the yin and yang, "Qian Dao into a man, Kun Dao into a woman", yin and yang convergence, then the birth of all things, all things according to the law of birth, so endless changes.
