The model Follow the Path of Dao distinguishes individual trigrams according to their qualitative dynamics. At the landmark points (Zhen, the thunder, Gen, the mountain, Sun, the wind / tree, Dui, the lake), the movement is dynamic, the direction is clear, and the momentum increases in terms of a positive disturbance.
At the landmark points Dui and Gen, momentum is created by adding a line opposite to the preceding character to its top. Both characters open up to the (respective other) sphere and allow themselves to be touched – by inner (Gen) or outer (Dui) impulses. In Zhen and Sun, on the other hand, the precarious momentum of the previous sign takes now a clear direction: towards inner (Zhen) or outer impulses (Sun) impulses.
