Gap-in 甲寅: Blue Tiger

The great tree in spring. 푸른 호랑이 in Korean.

A towering tree in early spring on a mountainside, a tiger resting at its roots.

Gap-in is wood on wood: the tall tree, 甲, on the Tiger, 寅, the first wood of spring. The stage is Taking office, the tree fully in its element. The picture is a great tree in its own season, strong, straight and growing fast.

People with this day pillar are often described as confident, independent and upright, with natural leadership. You sit on the Peer, read as strong self reliance. The tradition sees a person who stands tall, keeps their word and finds it hard to follow orders they disagree with.

With others you tend to be protective, principled and generous with guidance. You may be a natural head of the group. The growth point is flexibility: great trees survive storms by swaying.

What sits inside Gap-in

The branch 寅 In 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 Peer. Same element, same polarity as you: friends, equals, and your own independent streak.

Hidden stemTen god for 甲
戊 Mu, yang earth (7 days)Venture 편재
丙 Byeong, yang fire (7 days)Maker 식신
甲 Gap, yang wood (16 days)Peer 비견

In the twelve stage life cycle (십이운성 sibi unseong), 甲 in 寅 stands at Taking office (건록 建祿): the stem takes up its post, read as self reliance and steady strength in its own ground.

A question to sit with

Where would bending a little keep you standing longer?
