About this entry
天梁 sits five palaces forward of 天府, immediately before 七殺. Fallen at 巳, 申 and 亥 in the table the calculator uses, it is otherwise strong: temple at 子, 寅, 卯, 辰, 午 and 戌, prosperous at 丑 and 未, gaining at 酉.
The name means Heavenly Beam, and the book's own word for its transformed energy is 蔭, the shade that shelters what grows under it. It belongs to earth, is the second star of the Southern Dipper, and is lord of the Parents palace, with charge over long life. The first answer in 卷一 describes a candid and straightforward person, and it credits the star with softening what is violent. The book adds that it can restrain 破軍.
The book calls meeting 貪狼 or 巨門 in the same palace disorderly, a pairing the calculator's layout never produces and the text does not explain, and it says four harsh stars striking it leave a sprout that never flowers. The companions that do occur are 天同 at 寅 and 申, 太陽 at 卯 and 酉, 天機 at 辰 and 戌. It takes 化祿 under the stem 壬, 化權 under 乙 and 化科 under 己. The calculator's default chart gives the same three.
