Classical Eight Mansions doctrine reads the SW octant as one of Kua 1’s four unfavourable directions, specifically carrying the Jue Ming (絕命) assignment — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback).
Configuration
- Mountain: 坤 (Kūn) — SW octant, position 2 of 3, 217.5° – 232.5°
- Mountain type: trigram · yin earth element, yin polarity
- Personal kua: Kua 1 (坎 Kan) — East Life Group, natural direction N
- Eight Mansions assignment: Jue Ming (絕命) — unfavourable
- Eight Mansions domain: Total Loss / Severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback)
Kūn (坤) mountain context
Kūn (坤) is the second of three mountains in the SW octant (degrees 217.5° to 232.5° on the compass). It is a trigram-derived mountain, classified as yin earth (yin). Domain: Earth trigram, receptive nourishment, mother register, supportive ground.
坤 is a non-branch mountain (derived from the trigram doctrine) and does not enter the 三合 trine groupings directly.
Kua 1 (Kan) context
Kua 1 (坎 Kan) people belong to the East Life Group (東四命), with natural direction N (the water-element trigram register). Kua 1 (Kan) people are East Life Group — born under the Kan trigram (water, north). Thrive in N / E / SE / S facing properties; should avoid W / NW / SW / NE.
Kūn mountain read for Kua 1 Kan
Classical Eight Mansions doctrine reads the SW octant as one of Kua 1’s four unfavourable directions, specifically carrying the Jue Ming (絕命) assignment — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback).
What this means in practice: a property whose facing direction falls on 坤 mountain (within the SW octant), occupied by a Kua 1 Kan person, is read under classical Eight Mansions doctrine as carrying the Jue Ming register — total loss / severance — the most-watched negative direction (severe illness, financial collapse, life-changing setback). The cautious register is one of four unfavourable octants this kua has; the other three carry Huo Hai (mishaps), Wu Gui (5 ghosts), Liu Sha (6 killings), and Jue Ming (total loss) assignments depending on the kua. The specific assignment for SW for Kua 1 is Jue Ming.
Refinement within the octant: Kūn sits at position 2 of 3 within the SW octant. The SW octant has three mountains; classical doctrine applies the same Eight Mansions assignment to all three at the octant level, but specific-mountain refinements come from polarity matching (yin mountain vs yang mountain), san he trine groupings, and the mountain’s type (stem vs branch vs trigram). For a Kua 1 person, a yin mountain like Kūn pairs differently with the kua's water register than the octant's yang mountains do.
Why this is one input among four
The mountain-kua reading describes Eight Mansions doctrine’s baseline register only. The full audit also requires precise compass-degree facing measurement, the property’s Xuan Kong period chart, and integration across all occupants’ kuas. Master Sean Chan’s feng shui audit integrates all four layers on-site against your specific property.
