The Dragon Gate Eight Directions (龍門八局) Water Formula classifies wealth-relevant water flow by the compass direction from which water visibly enters a property. North water enters under the Kan 坎 trigram (water in its native element) at the 子 Zi mountain position. In classical landscape-based feng shui, this is a literal river or stream visible from the property's facing side; in modern urban application, it is the busy northbound street, the freeway lane carrying traffic in from the north, or the drainage path that flows from north toward the building.
Why is north-incoming water doctrinally significant?
The Kan trigram 坎 represents water as native element — water arriving from the north reaches the property in its strongest elemental signature, neither dispersed by transit through other compass sectors nor weakened by mismatch with the dominant element of the angle. Classical Dragon Gate texts rank north-incoming water among the most powerful water-flow configurations for properties with sitting directions in the southern arc (午 Wu, 丁 Ding, 未 Wei). The mechanism: north water 'feeds the seat' of a south-sitting property in the canonical 坐北朝南 (sit north, face south) configuration that is the historical default for residential and ceremonial buildings in Chinese tradition. Practitioners auditing a south-facing property with visible north-entering water typically classify it as auspicious unless the water is foul, stagnant, or 'rushing' (high-velocity, T-junction, or above flood-stage in volume).
Sitting-direction interactions
North-incoming water is not universally favorable. Its auspiciousness is conditional on the property's sitting direction: STRONGLY FAVORABLE for south-sitting (午, 丁) and southeast-sitting (巳, 丙) configurations. NEUTRAL for east-sitting (卯, 乙) and west-sitting (酉, 辛) configurations — north water passes the sides without engaging the seat. UNFAVORABLE for north-sitting (子, 癸) configurations — water entering directly behind the property is classically described as 'water at the back, vacuum at the seat,' undermining the building's stable resting axis. The Dragon Gate ranking changes accordingly: for south-sitting structures, north-incoming water can elevate a property's wealth-attraction profile by one classification tier; for north-sitting, it depresses by one tier. The full audit always pairs water direction with sitting direction before assigning a ranking.
Modern urban proxies for north-incoming water
Modern urban environments typically replace literal water with traffic-as-water proxies. North-incoming water in city contexts: a major avenue running north-to-south where the morning peak flows from the north (north-side suburbs commuting south to commercial centers) is the strongest urban analog. A freeway exit dropping cars into the property's neighborhood from the north qualifies. Underground subway lines running north-to-south carry water-equivalent qi but with weakened intensity due to the subterranean position. Drainage paths matter: any storm drain or culvert that visibly carries runoff from north toward the property reinforces the Kan-trigram signature even in absence of street-traffic proxies. The audit checklist for urban properties: visible street flow (primary), freeway proximity (secondary), drainage paths (tertiary), and underground rail (quaternary).
