The upper hexagram and the lower hexagram are not only divided into far and near in space, indicating a spatial connection from far to near, but also divided into virtual and real. The upper hexagram is virtual and the lower hexagram is real. If a hexagram is used to represent a person, the lower hexagram represents the body and the upper hexagram represents the mind. It is said that the sky is pure and the earth is turbid. The mind is always lighter and clearer than the body, while the body is heavy and turbid. The lower hexagram is the foundation, and the upper hexagram is the development.
When a hexagram appears, you can know the current situation by looking at the hexagram. If you look at the hexagram, you can see the future.
The upper hexagram represents time, and the lower hexagram represents space. Why do you say this? Because the upper hexagram is the sky, and the movement of celestial bodies is time. The lower hexagram is earth, and the earth is the space in which it is located. Therefore, the functions of the upper and lower hexagrams are different.
The ancients also left behind two sentences: the sky has yin and yang, and the earth has hardness and softness. Why does heaven talk about yin and yang? Yin and Yang are the concept of time, the representation of light and darkness. In terms of hardness and softness, hardness and softness, hardness and softness, these are forms that can be directly touched and felt.
If you understand that images are formed in the sky and formed on the earth, the sky has yin and yang, and the earth has hardness and softness. The upper hexagram is heaven, the lower hexagram is earth, the upper hexagram is time, and the lower hexagram is space. Interpreting hexagrams under the guidance of this concept will bring you to a whole new level.
For example, in the Ditiantai hexagram, the upper hexagram represents time, which means there is darkness ahead. The lower hexagram represents that the light on the earth is constantly expanding and the masculinity is rising. Ditiantai comes from the Kun hexagram. Originally, the six roots of the upper and lower hexagrams were all yin yarns. Now the three lower yin yarns have been occupied by yang yarns, which is equivalent to the Kun hexagram losing half of its territory. This creates a momentum, and the next thing Yang Yao has to do is to continue moving forward and eat the remaining half of Yin Yao above. Therefore, although the hexagram Ditiantai is dark ahead, it will soon be occupied by light, which means there is a lot of room for expansion.
