A young tree standing over a frozen spring, roots already drinking from the water below the ice.
Gap-ja is the first of the sixty pillars, so it carries the feeling of a first page. The stem 甲 is a tall tree and the branch 子 is the Rat: deep winter water at midnight. A tree in winter is not growing yet, but its roots sit in water, fed and waiting for spring.
People with this day pillar are often described as bright, principled and quietly ambitious, with a mind that keeps learning. The water under the tree reads as a constant supply of ideas and support, and the tradition sees a person who studies before acting. Winter also brings a certain coolness: you may be warmer inside than you look.
With other people you tend to be the one with a plan and the patience to wait for the right moment to start it. You may like mentors and may become one. The growth point is sunlight: a Gap-ja chart often enjoys warmth, company and a reason to leave the study.

What sits inside Gap-ja
The branch 子 Ja holds hidden stems (지장간 jijanggan). Seen from the day master 甲, each one takes a ten god role. The last one listed is the main stem, so this pillar is said to sit on the Mentor. What feeds your element, opposite polarity: support, learning, care and a sense of home.
| Hidden stem | Ten god for 甲 |
|---|---|
| 壬 Im, yang water (10 days) | Outsider mind 편인 |
| 癸 Gye, yin water (20 days) | Mentor 정인 |
In the twelve stage life cycle (십이운성 sibi unseong), 甲 in 子 stands at Bathing (목욕 沐浴): the newborn is washed, read as a sensitive, changeable stage with charm and some restlessness.
