gui-chou day pillar

In 癸丑 the seat restrains the stem, since earth dams water, and that reversal of direction is what sets the pair apart. 己 inside 丑 is Seven Killings to 癸, which only means yin earth bearing on yin water at matching polarity. The other stems are 癸, the Friend, and 辛, Indirect Resource, and 三命通會 replaces 辛 with 庚, a Direct Resource for this day master.

三命通會 卷一 pairs this entry with 壬子 and flips the complaint: 伤水少之木, wood harmed by too little water. Metal, water and autumn are what it is said to like, so the two Mulberry Wood pairs ask for opposite things.

The stage here is Crown and Belt, 冠帶. Counting 癸 backward from its Growth at 卯 gives 寅 and then 丑, and the name marks a stem dressed for adult standing in the life metaphor.
