Classical Eight Mansions doctrine reads the NE octant as one of Kua 9’s four unfavourable directions, specifically carrying the Huo Hai (禍害) assignment — mishaps, minor accidents, gossip, daily friction (mildest).
Configuration
- Mountain: 艮 (Gèn) — NE octant, position 2 of 3, 37.5° – 52.5°
- Mountain type: trigram · yang earth element, yang polarity
- Personal kua: Kua 9 (離 Li) — East Life Group, natural direction S
- Eight Mansions assignment: Huo Hai (禍害) — unfavourable
- Eight Mansions domain: Mishaps, minor accidents, gossip, daily friction (mildest)
Gèn (艮) mountain context
Gèn (艮) is the second of three mountains in the NE octant (degrees 37.5° to 52.5° on the compass). It is a trigram-derived mountain, classified as yang earth (yang). Domain: Mountain trigram, stillness, transition, the youngest son register.
艮 is a non-branch mountain (derived from the trigram doctrine) and does not enter the 三合 trine groupings directly.
Kua 9 (Li) context
Kua 9 (離 Li) people belong to the East Life Group (東四命), with natural direction S (the fire-element trigram register). Kua 9 (Li) people are East Life Group — born under the Li trigram (fire, south). Thrive in S / SE / E / N facing properties; should avoid NE / SW / W / NW.
Gèn mountain read for Kua 9 Li
Classical Eight Mansions doctrine reads the NE octant as one of Kua 9’s four unfavourable directions, specifically carrying the Huo Hai (禍害) assignment — mishaps, minor accidents, gossip, daily friction (mildest).
What this means in practice: a property whose facing direction falls on 艮 mountain (within the NE octant), occupied by a Kua 9 Li person, is read under classical Eight Mansions doctrine as carrying the Huo Hai register — mishaps, minor accidents, gossip, daily friction (mildest). 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 NE for Kua 9 is Huo Hai.
Refinement within the octant: Gèn sits at position 2 of 3 within the NE octant. The NE 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 9 person, a yang mountain like Gèn pairs differently with the kua's fire register than the octant's yin 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.
