Classical Eight Mansions doctrine reads the NE octant as one of Kua 2’s four favourable directions, specifically carrying the Sheng Qi (生氣) assignment — career luck, prosperity, opportunity (most auspicious).
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 2 (坤 Kun) — West Life Group, natural direction SW
- Eight Mansions assignment: Sheng Qi (生氣) — favourable
- Eight Mansions domain: Career luck, prosperity, opportunity (most auspicious)
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 2 (Kun) context
Kua 2 (坤 Kun) people belong to the West Life Group (西四命), with natural direction SW (the earth-element trigram register). Kua 2 (Kun) people are West Life Group — born under the Kun trigram (earth, southwest). Thrive in SW / NW / W / NE facing properties; should avoid E / SE / S / N.
Gèn mountain read for Kua 2 Kun
Classical Eight Mansions doctrine reads the NE octant as one of Kua 2’s four favourable directions, specifically carrying the Sheng Qi (生氣) assignment — career luck, prosperity, opportunity (most auspicious).
What this means in practice: a property whose facing direction falls on 艮 mountain (within the NE octant), occupied by a Kua 2 Kun person, is read under classical Eight Mansions doctrine as carrying the Sheng Qi register — career luck, prosperity, opportunity (most auspicious). The favourable register is one of four favourable octants this kua has; the other three carry Sheng Qi (career), Tian Yi (health), Yan Nian (relationships), and Fu Wei (stability) assignments depending on the kua. The specific assignment for NE for Kua 2 is Sheng Qi.
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 2 person, a yang mountain like Gèn pairs differently with the kua's earth 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.
