Innate gossip: A space-time, with no direction, a three-dimensional circle, a moving sphere and eight directions.
Gossip the day after tomorrow: no time \ space, orientation, plane square, static square, eight squares.
Fengshui truth: nature is the body, and the day after tomorrow is the use, mainly the use, and the key is the orientation.
I ching principle: everything (from the universe to the three realms, to small particles and small molecules. All kinds, endless. ) body use merge, and then daily use.
For example, make southeast and northwest cross,
Geomantic omen theory: Set a point (Taiji point) on the cross and look around the cross. There are left and right, and there is no difference between up and down.
The Book of Changes says: Stand up the cross and keep the Tai Chi point unchanged. In this way, if you look at the four directions pointed by the cross, there will be left and right points.
With this understanding, the above three points should be easy to understand.
