The configuration sits opposite the Parents palace (父母宮) on the Health–Parents (疾厄–父母線), with the trine reading drawing in Siblings, Health, Property, Parents. 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 warmth and visibility expresses through physical body and constitution as a register that reveals the body’s baseline strengths and pressure points.
At the textbook level, Tai Yang in the Health Palace reads as chart’s outward-facing public energy bringing its register to physical body and constitution. Teachers, broadcasters, politicians, sales leaders, religious figures are common manifestations. Tai Yang’s characteristic risk — over-extension when scope outruns warmth; reputation damage from the Jia (甲) 化忌 — surfaces specifically through physical body and constitution 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 Health Palace and the opposing Parents Palace. Synthesising these layers across a real chart is the practitioner skill the Zi Wei Dou Shu Masterclass teaches.
