Compass School (理气派)

‘Compass School’ is an umbrella English label.

Definition

Compass School (理气) uses luopan bearings, cycles, and star grids—Eight Mansions, San He water methods, Xuan Kong flying stars—to score directions. It pairs with Form School rather than replacing it.

How to Check

Log sitting and facing mountains before software.
Name the lineage (Eight Mansions vs flying stars) on every report.

Classical Basis

Eight Mansions Mirror and Shen’s Xuan Kong works are common references; plate layers differ by lineage and are not interchangeable.

Application

·Flats often debate which door sets facing—state your rule.

Common Effects

·Mixing San He water rules with Xuan Kong replacement hexagrams creates contradictions.
·One-degree sitting errors shift every palace.

Remedy Direction

Stick to one compass school per case; keep measurement records.

Caveats & Debate

No universal rule for sitting in towers; disclose assumptions.
