Gui Chou Day Pillar

Dew freezing on hard ground — it can neither soak in nor evaporate, so it becomes frost. Reserved to the point of being locked in.

Mulberry feeds silkworms — the tree draws no attention, and nothing else does its job.

In the sixty-pillar cycle each image is shared by exactly two pillars. 癸丑 shares Mulberry Wood with 壬子, though the two differ in polarity, animal and hidden stems.

Guǐ carries the image of rain, dew, a spring underground. That is this pillar's baseline; the branch it is paired with decides the rest.

Chǒu is Earth, yin in polarity, and carries the Ox.

Hidden stems: every branch conceals stems of its own, in descending weight — Jǐ Earth (60%), Guǐ Water (30%), Xīn Metal (10%).

the branch controls the stem (Authority)

The ground here constrains the stem: disciplined, able to carry pressure, and permanently a little tensed — the release has to be deliberate.

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.
