The compass is mainly composed of a magnetic needle in the center of a disk and a series of concentric circles, each of which represents the ancient people in China's understanding of a certain level of information in the cosmic system.
The ancients in China believed that man's gas field was controlled by the gas field of the universe, that harmony between man and the universe was auspicious, and disharmony between man and the universe was fierce. So, by experience, they put all levels of information in the universe, such as the stars in the sky, everything represented by the five actions on the earth, heavenly stems and earthly branches and so on. , all on the compass. ?
Geomantic omen is to find the most suitable position or time for a specific person or thing through the rotation of a magnetic needle. Although the concept of "magnetic field" is not mentioned in geomantic omen, the coordination of the directions, orientations and intervals of each layer on the compass implies the law of "magnetic field".
The first lap: Haichi compass, used for orientation. Point south.
The second circle: gossip the day after tomorrow, orientation symbols
The third circle: the name of gossip the day after tomorrow
The fourth circle: the representatives of yin, yang and five elements in eight directions.
The fifth circle: one person, one thing and one thing in eight directions.
The sixth circle: heavenly stems and earthly branches in eight directions (zodiac) and time representative.
The seventh circle: Zodiac, representing harmony, association, impulsiveness, punishment (after looking up the table), heavenly dryness and temperament.
The eighth circle: spring, summer, autumn and winter, the representation of orientation, yin and yang.
Ninth circle: Eight directions, represented by the 24 solar terms, each direction has three kinds of smells.
2. Square frame:
① The four sides of the square frame represent the four sides of plots, buildings and houses.
② The red cross line in the middle of the four sides of the square frame is the reference line for viewing the building orientation (the figure below is a simple compass).
Step one:
If you want to predict a plot, pull an edge line on the north and south sides of the plot as the line of the compass. Turn the middle compass so that it overlaps the north and south in the sea pool.
(Note: the red direction of the compass is always south, which should overlap with the south marked in the sea pool, not the north).
At this time, you can see where it points by observing the crosshair (azimuth datum line) in the middle of the four sides of the outer frame. As shown in the figure, because the wall is parallel to the longitudinal datum line, and the longitudinal datum line points to the southeast, we can know that the building faces the southeast.
Step 2: Look at the representative on the compass and mark it.
After determining the orientation, record the shape and orientation of the building or plot on geomantic taiji paper (attached drawings can be made by yourself). Gray in Taiji paper represents plots or buildings.
② Mark the defective position.
(3) Mark the location of the tangible evil spirits.
④ Mark the door opening position.
⑤ Check the good and bad luck table of opening the door in eight directions. Point out the good luck and bad luck on every side of the plot or building.
