Wu Zi Day Pillar

A mountain holding a lake in place: it makes the moving thing stay. Dependable, and sometimes airless.

Lightning: enormous, instantaneous, and gone — force without duration.

In the sixty-pillar cycle each image is shared by exactly two pillars. 戊子 shares Fire of the Thunderbolt with 己丑, though the two differ in polarity, animal and hidden stems.

Wù carries the image of a mountain. That is this pillar's baseline; the branch it is paired with decides the rest.

Zǐ is Water, yang in polarity, and carries the Rat.

Hidden stems: every branch conceals stems of its own, in descending weight — Guǐ Water (100%).

the stem controls the branch (Wealth)

What this pillar stands on is what it can command: practical, good with resources, and prone to treating everything as a thing to be managed.

Note: this reads the day pillar alone. A full chart has three more pillars plus the luck cycles, and the balance is only settled by all of them together.
