The configuration sits opposite the Travel palace (遷移宮) on the Self–Travel (命遷線), with the trine reading drawing in Self, Wealth, Career, Travel. Tai Yang transforms 化祿 under Geng (庚), 化權 under Xin (辛), 化忌 under Jia (甲); does not transform 化科.
The practitioner’s note: Tai Yang’s natural authority expresses through personality and life direction as a register that sets the chart’s register at its narrative spine.
The textbook reading: chart-holders relate to personality and life direction through chart’s outward-facing public energy. Common signatures include teachers, broadcasters, politicians, sales leaders, religious figures. Tai Yang’s characteristic risk — over-extension when scope outruns warmth; reputation damage from the Jia (甲) 化忌 — surfaces specifically through personality and life direction when supporting conditions are absent. Pairings with Tian Liang reinforce this picture; pairings with the Four Killings (擎羊, 陀羅, 火星, 鈴星) sharing or opposing the palace can flip it.
Beyond the baseline above, four further dimensions shape a practitioner-grade reading: which auxiliary stars (左輔, 右弼, 文昌, 文曲, 天魁, 天鉞) share or oppose the palace, whether any of the Four Killings (擎羊, 陀羅, 火星, 鈴星) sit in the same or opposing palace, whether self-transformations (自化) on adjacent palaces alter the configuration’s energy, and how the current 10-year and annual luck cycles activate or suppress what sits in the Self Palace and the opposing Travel Palace. Synthesising these layers across a real chart is the practitioner skill the Zi Wei Dou Shu Masterclass teaches.
