Sitting opposite the Siblings palace (兄弟宮), this configuration occupies the Siblings–Friends (兄僕線) and closes the peer-network axis with Siblings: Children · Friends · Parents · Siblings. Tai Yang transforms 化祿 under Geng (庚), 化權 under Xin (辛), 化忌 under Jia (甲); does not transform 化科.
Where Tai Yang sits in 僕役宮, the register typically reads through how the chart-holder relates to the people who report to them or orbit them — though the specific intensity depends heavily on supporting stars.
The textbook reading: chart-holders relate to subordinates and broader network 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 subordinates and broader network 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.
Practitioners reading at depth weigh four further layers that this reference does not develop: 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 Friends Palace and the opposing Siblings Palace. Synthesising these layers across a real chart is the practitioner skill the Zi Wei Dou Shu Masterclass teaches.
