In the Book of Burial, the earth has four potentials, and the gas comes from all directions. What do you mean ...

"The Earth has four potentials, and the air comes from all directions" mentioned in the Book of Burial means that the terrain has four potentials: high, low, flat and straight, while the weather continuously flows in from four positive directions (southeast, northeast, southwest and northwest) and four-dimensional directions (southeast-northwest and northeast-southwest).

Among them, the four potentials are related to the situation of Feng Shui. In China's geomantic omen, it is emphasized that "storing gas by shape", that is, topography is an important factor for storing wind and gathering gas. Terrain not only affects the flow direction and size of gas, but also affects the layout of buildings, cemeteries and other facilities. Therefore, it is very important for feng shui masters to understand the terrain trend.

At the same time, the weather is also an indispensable factor in Feng Shui. In geomantic omen, weather is considered to be an important factor to produce and regulate the qi of yin and yang. Qi flows in from eight directions, so that the earth is balanced between yin and yang and everything is flourishing. Therefore, qi in all directions is also an important concept in Feng Shui.

Generally speaking, "soil has four potentials, and qi comes from all directions" is an important concept in geomantic omen, which expresses the influence of topography and weather on geomantic omen and is an important basis for geomantic omen masters to arrange geomantic omen.
