The Heavenly Stems — the ten characters of the sky
Where the Korean word for the powerful party in a contract comes from
A story to start
Why, in a Korean contract, is the commissioning party called <i>gap</i> and the supplier <i>eul</i>? Why were old school grades marked gap, eul, byeong, jeong? The answer is today’s subject, the ten Heavenly Stems: Gap, Eul, Byeong, Jeong, Mu, Gi, Gyeong, Sin, Im, Gye. These ten characters, representing the energies of the sky, were also the East’s alphabet for counting order — first place gap, second eul. The Korean word for abuse of contractual power comes, in fact, from a three-thousand-year-old character.
🏺 A spoonful of origin
The Stems belong to the oldest layer of written record in the East. Some three thousand years ago, the oracle bone inscriptions of the Shang dynasty — divination records carved into turtle shell — were already counting days with the Stems, and Shang kings even carried Stems in their names. A bundle of ten days was called a <i>sun</i>, which is why Korean still says early, middle and late <i>sun</i> of a month. Every time you say “shall we meet around the middle of the month?” you are using a three-thousand-year-old calendar.
📖 The main point — the character of the ten
The Stems are the Five Elements multiplied by polarity, making ten. Yang Wood, Gap (甲), is the great tree that grows straight for the sky — leadership and pride. Yin Wood, Eul (乙), is ivy and wildflower — flexibility and survival. Yang Fire, Byeong (丙), is the sun that lights everything — passion and impartiality. Yin Fire, Jeong (丁), is a candle in the dark — fine warmth and concentration. Yang Earth, Mu (戊), is the mountain — weighty trust. Yin Earth, Gi (己), is fertile field — substance and nurture. Yang Metal, Gyeong (庚), is raw ore and iron — decision and loyalty. Yin Metal, Sin (辛), is the cut jewel — precision and perfectionism. Yang Water, Im (壬), is the sea — scale and capacity. Yin Water, Gye (癸), is drizzle — cleverness and feeling. Hang one picture in your head per character. Myeongri is, in the end, the study of making stories out of these pictures.
🔍 In practice
The top row of your four pillars — all four characters — are Stems. Of those, the Stem of the third pillar is “you,” which we cover properly in two lessons’ time. For today, check which Stems appear in your chart and pair them with the characters above. “My mother’s Day Master is Gyeong Metal? No wonder she’s so clear about where things end.” Once moments like that arrive, the study gets fun.
🗣️ The story people tell
The oracle bones were discovered in 1899 by the Qing scholar Wang Yirong, in “dragon bones” being sold as medicine. Fragments people were grinding up as a malaria remedy turned out to carry ancient writing. Humanity’s oldest record of the Stems nearly ended up entirely as herbal decoction. Scholars still joke, half in lament, about how much history got brewed.
🧭 Working through the situations
Here is a taste of stress relief by Day Master. Gap Wood can’t bear being bent — anything that climbs, like hiking, is the specific remedy. Eul Wood is stressed by constraint — tending plants, walking, gentle expansion. Byeong Fire wilts when ignored — it draws energy from being among people, so a gathering is the restorative. Jeong Fire is poisoned by noise — it recharges absorbed like a candle in a quiet café. Mu Earth finds change exhausting — tidying a familiar space is healing. Gi Earth’s worst state is feeling useless — a vegetable patch, cooking, anything that raises something. Gyeong Metal is stressed by the unfinished — exercise, sweat, the sense of a thing completed. Sin Metal is sensitive to blemish — trimming nails, ordering a desk, detail care. Im Water is poisoned by confinement — a walk by open water. Gye Water suffers emotional overload — journalling, letting it flow out.
❓ Frequently asked
Q. Gap is first, so is Gap Wood the best? No. Gap-Eul-Byeong-Jeong were simply characters for counting order; there is no ranking between them. It doesn’t follow that Gye Water (tenth) is a lesser chart than Gap Wood (first). Q. Do I have to memorise the Chinese characters? For the beginner course, the romanisation and the image are enough. Getting your eye used to distinguishing lookalikes such as 甲, 由 and 申 does make reading a calendar easier. Q. What if the same Stem appears several times in a chart? That energy is that much stronger. Three Byeong Fires is a chart with three suns overhead — the “excess” reading from lesson ten applies directly. Where a character matches the Day Master in particular, it reads as a being resembling you (the Friend star, in the intermediate course).
✏️ Today’s one step
Learn the ten Stems in order — Gap Eul Byeong Jeong Mu Gi Gyeong Sin Im Gye. Give it a rhythm and it goes quickly (Gap-Eul-Byeong-Jeong / Mu-Gi / Gyeong-Sin / Im-Gye). And practise writing at least your own Day Master in the Chinese character. You should be able to write your own Day Master the way you write your own name.
