Xuan Kong Da Gua Deep Layer (玄空大卦深層)
This module extends the existing Xuan Kong Da Gua curriculum from a 64-hexagram compass reference into the deeper diagnostic vocabulary: Gua Qi, Gua Yun, spouse-pair resonance, substitute divisions, and City Gate logic. The student should already know that each hexagram occupies 5.625 degrees. The advanced question is no longer simply which hexagram a direction occupies, but whether its qi, period, pairing, and side-gate relationships can carry the intended use.
Four Study Layers
- Gua Qi: the hexagram's energetic number and its He Tu element relationship.
- Gua Yun: the period quality used to compare direction, timing, and activation suitability.
- Spouse Pair: the yin-yang or opposite-arc relationship used to test whether a pair communicates or separates.
- City Gate: the side-door logic that checks whether adjacent palace qi can receive the current or future prosperity star.
City Gate work is especially easy to misuse. A side direction is only a candidate until the chart confirms its star behavior, yuan-long purity, and relationship to the facing palace. Teaching it as a simple good direction would erase the method's purpose.
Measurement Discipline
Xuan Kong Da Gua deep work is measurement-sensitive. The 24 Mountains are not enough; the student must distinguish the center of a mountain, side divisions, substitute lines, and exact 64-hexagram placement. The learning outcome is precision plus restraint: record the degree, map the hexagram, compare qi and yun, then decide whether the site deserves further activation.
