"Left and right, the way of Yin and Yang is also; Fire and water are signs of yin and yang. " -Neijing.
Male is yang, female is yin; The left is yang and the right is yin (so there is a saying that "men are left and women are right"); The upper part is yang and the lower part is yin; Fire is yang and water is yin; Ascending to Yang, descending to Yin; Floating as yang, sinking as yin. ...
The black and white dots in the two big commas are called "Yang has Yin, Yin has Yang". According to the fact that left, up, up, floating and white are masculine, the chess piece on the left represents "Yang", which is white and floats upward. Similarly, the one on the right stands for "Yin", which is black and sinks, so it forms an anti-S shape in the middle (note that it is an anti-S shape, not an "S" shape. Even if you look backwards, the middle is inverted "S" shape, unless you look backwards. Black and white, representing yin and yang, heaven and earth; The boundary between black and white is the division of yin and yang between heaven and earth. Black dots on a white background indicate that there is yin in yang, and white dots on a black background indicate that there is yang in yin. This is Artest's Tai Chi Yin-Yang diagram (Yin-Yang fish in Tai Chi diagram correct each other).
"Left rises and right falls, left white and right black". Taiji diagram is an important image to study the principle of Zhouyi. Too meaningful; Extremely limited, that is to say, as for limited, it doesn't mean equal. It includes not only extreme principles, but also time and space restrictions from big to small. If you let it go, you will be six in one, and the volume will be hidden in your heart. It can be greater than any quantity but not beyond the circumference and space, or less than any quantity and not equal to zero or zero. These are the meanings of Tai Chi.
The universe is infinite, so it is called Tai Chi, but the universe is tangible, that is, it has substantial content. According to the viewpoint of Yi-ology, tangible things come from the intangible, so they are infinite, which is Tai Chi. Taiji is a dynamic entity, that is, the universe is moving. When it moves to a certain extent, it becomes relatively static, and when it is static, it produces Yin. So when it moves and stands still, Yin and Yang are the root of each other and run in infinity.
The same is true of nature. The growth set of yin and yang in the four seasons of cold and summer, that is, the growth law of everything, includes yin and yang and five elements. As far as yin and yang are concerned, "the avenue becomes a man, and Kun Dao becomes a woman." Yin and yang are combined, and everything is born. Everything is born according to this law, so it changes endlessly. These contents put forward three schemes, namely, the way of establishing heaven, the way of standing on the ground and the way of educating people, that is, the way of three talents, which is the so-called "six moves and three poles."
