About this entry
天同 closes a tight run of three stars, five palaces behind 紫微 and right beside 武曲, and two empty palaces separate it from 廉貞. The table gives it temple at 巳 and 亥 and fallen at 午, with 丑 and 未 not gaining and the rest in between.
Water is its element in the book, with water and metal in one 卷二 list, and it is lord of the Fortune palace, with a transformed energy called 福, blessing. The passage attributed to 希夷先生 describes a modest and mild character and says the star fears neither 七殺 nor the harsh stars sharing its space. That is unusually warm language for this text, and it attaches the condition elsewhere that the star be unbroken for the good reading to hold.
天同 shares a palace with 太陰 at 子 and 午. 巨門 joins it at 丑 and 未, 天梁 at 寅 and 申, and elsewhere it has the palace to itself. The transformations are 化祿 from 丙, 化權 from 丁, and in a 庚 year the Wikisource text gives it 化忌, which the calculator follows.
