What the Four Pillars actually are
The “eight characters” behind the Korean phrase for fate — four pillars, eight characters
A story to start
“Look at that cat — what a life.” In Korean, the word a grandmother uses there is <i>paljja</i>, literally “the eight characters.” A hard life, changing your life, blaming your life — Koreans use that word daily without ever having studied Saju. So what exactly are those eight characters? The short answer: they are the moment of your birth written out in eight characters. Today we open up what those eight are.
🏺 A spoonful of origin
Saju (四柱) means “four pillars.” The year you were born is the first pillar, the month the second, the day the third, the hour the fourth. As you raise four posts to build a house, the idea is that a person’s structure of fate stands on four pillars. The framework began settling in Tang-dynasty China, was completed under the Song, and came deep into Korean culture through Goryeo and Joseon. Joseon’s royal observatory, the Gwansanggam, even had a discipline called Myeonggwahak, and Saju specialists were selected by state examination. Long before it was a back-alley fortune-teller’s trade, this was a palace science.
📖 The main point — two characters per pillar
Each pillar carries two characters: the heavenly character on top (the Heavenly Stem) and the earthly character underneath (the Earthly Branch). Four pillars × two characters = eight characters. That is <i>paljja</i>. 2026, for instance, is a Byeong-o year: Byeong (丙) is the sky character and O (午) is the earth character. Year, month, day and hour each get two like this. Myeongri (命理學) is the study of reading the combination of energies held in those eight characters to interpret inborn temperament and the flow of a life. Less a divination that “hits” the future than something closer to a meteorology of energy, analysing the season and climate of the moment you were born.
🔍 In practice
Better to see once than hear a hundred times. Put your birth date in at the top of this site and press the button. Four cards appear — those are your four pillars, and the two large characters on each are the Stem on top and the Branch below. You don’t need to know their meanings yet. Just note that these eight are yours. Over the next ten lessons you’ll get very familiar with them.
🗣️ The story people tell
The Korean phrase “to fix your eight characters” originally meant remarrying — the thought being that when the spouse pillar changes through marriage, the life changes. What’s amusing is the joke modern Myeongri practitioners make: you can’t fix the eight characters, but you can fix the reading. The same eight characters get read darkly by one person and brightly by another — and the Korean name of this site, which means roughly “a chart is what you make of it,” comes from the same philosophy.
🧭 Working through the situations
Let me translate in advance the phrases you’ll hear at a reader’s office. “Your original chart is good” — the original chart means the eight characters you were born with. “You’re in a period where the Luck Pillar changes” — Luck Pillars are the large flow that shifts in ten-year units (covered in the advanced course). “Your day pillar is strong” — the day pillar is the two characters of your birth day, the seat of you and your spouse. And if you don’t know your birth hour, don’t worry: with the six characters minus the hour pillar, the core interpretation — Day Master, month Branch and the rest — works perfectly well. The hour pillar is the seat of later life and children, so only that part loses resolution.
❓ Frequently asked
Q. Twins have the same chart — why are their lives different? A long-standing puzzle in the field. As two houses built from the same blueprint differ by site and upkeep, the modern answer is that a chart is a map of temperament and flow and does not determine a whole life. It is also the best evidence that Myeongri is not determinism. Q. Does changing my name change my chart? Name numerology is a separate discipline. The eight characters don’t change when you change your name. Q. Isn’t Saju superstition? Taken as supernatural prophecy it becomes superstition; read as a symbolic system built from thousands of years of observing people, it becomes humanities. This course takes the latter position.
✏️ Today’s one step
Pull up your eight characters and put them in a note on your phone — the Chinese characters with the Korean romanisation beside them (Byeong-o, Sinsa, and so on). From the next lesson, that note is your textbook. If you can, pull up one family member’s chart too — having something to compare against doubles the speed of learning.
