What it is
Xuan Kong Da Gua (玄空大卦, "Mysterious Void Great Hexagram") is an advanced branch of Xuan Kong (Time-Space) Feng Shui refined during the Qing Dynasty (1644–1912) that maps the 64 I Ching hexagrams onto compass directions. By identifying the hexagram of a building's sitting and facing directions, practitioners can assess compatibility between structure and occupants, identify auspicious sectors, and optimize spatial arrangement at a level of detail beyond standard Flying Stars.
Advanced hexagram-based spatial analysis.
How it works
Each of the 360 degrees of the compass maps to one of the 64 hexagrams through the mountain-ring system. Your home's sitting direction produces a sitting hexagram, and the facing direction produces a facing hexagram. Each sector of the home also has its own hexagram. Compatibility is assessed through trigram relationships (upper and lower trigrams of each hexagram), elemental interactions, and the "host-guest" relationship between building and occupant energies.
Key components
- 64 Hexagrams — The full set of I Ching hexagrams mapped onto the compass. Each hexagram combines two trigrams (upper and lower) and carries specific energetic qualities.
- Mountain Ring — The 24 mountains of the Chinese compass, each subdivided into 3 sectors, mapping 72 compass segments to specific hexagrams via the Early Heaven and Later Heaven trigram arrangements.
- Sitting/Facing — Every building has a sitting direction (back/support) and facing direction (front/openness). Their hexagrams determine the fundamental energy character of the space.
- Trigram Compatibility — Upper and lower trigrams of sitting and facing hexagrams are compared for harmony. Compatible combinations (like same-element or productive-cycle pairs) indicate a favorable space.
- Sector Analysis — Each compass sector of the home carries its own hexagram energy. Important rooms (bedroom, office, kitchen) should ideally occupy sectors with favorable hexagram combinations.
- Elemental Relationships — Hexagram interactions follow the Five Element cycle. Production relationships are favorable; controlling relationships may create challenges depending on context.
Your reading
Once you have a K A X A N T A account, this section fills with your actual Xuan Kong Da Gua values — computed once from your birth data and refreshed as transits shift. Until then, this is the shape of what you'll see.
Every number in your reading traces back to a classical calculation — no AI fabrication, no synthetic guesswork. If something looks wrong, it's almost always birth-data accuracy.
How K A X A N T A reads this
K A X A N T A calculates sitting and facing hexagrams from your home's compass direction, sector hexagrams for all 8 directions, trigram compatibility ratings, and elemental relationship assessments. Requires house facing direction input in Settings. Results integrate with the broader Feng Shui analysis for a complete environmental picture.
I don't read Xuan Kong Da Gua in isolation — I weigh it against the other eight systems based on the question you're asking. Decisions, timing, psychology, and environment each have their own primary authority; Xuan Kong Da Gua contributes to the ones where its lineage is strongest.
Common questions
History & lineage
A branch of Xuan Kong (Time-Space) Feng Shui refined during the Qing Dynasty (1644-1912). Based on the 64 hexagrams of the I Ching.
K A X A N T A presents Xuan Kong Da Gua faithfully, as its lineage presents itself. We don't sacralise it, we don't reduce it. If it consistently describes you better than generic advice would, use it. If not, lean on the other eight.
