The Samil Singo (삼일신고, 三一神誥) is a Korean scripture of 366 Chinese characters, written in five short chapters. Four of them look outward — at heaven, at God, at the heavenly palace, at the world. The fifth looks straight at you. That fifth chapter is the Truth Chapter, the Jinrihun (진리훈, 眞理訓), and it is where most readers stop and stay.
Here is what the Truth Chapter says, in one breath. You were given three true things — seong, myeong, and jeong — and unlike everything else in the world, you received them whole. Then you lost sight of them, and three delusions took root in their place: mind, energy, and body. Those three open three roads — feeling, breath, and contact — which branch into eighteen states that most of us spend our days chasing. And the way home is not to acquire anything new. It is to turn the whole movement around: the false, turned back, becomes true.
This article maps the whole scripture briefly, tells you honestly what can and cannot be said about where it came from, and then walks the Truth Chapter slowly, in the order it was written.
What is the Samil Singo?
The name is a description. Sam (삼, 三) means three. Il (일, 一) means one. Singo (신고, 神誥) means a divine teaching — words proclaimed rather than argued. Put together: the divine teaching of the three and the one.
That title is the whole idea. Wherever this scripture looks, it finds a three that never actually left its one. Korea's other short scripture, the Cheonbugyeong, states the same shape from the outside: everything comes from one, the one divides into three poles — heaven, earth, and the human being — and everything returns to the one. The Samil Singo takes that shape and turns it inward, into a human life.
The text is short: 366 characters, traditionally counted chapter by chapter. Here is the whole map.
| # | Chapter | Length | What it says |
|---|---|---|---|
| 1 | Heaven (천훈, 天訓) | 36 characters | The blue overhead is not heaven. Heaven has no form and no edge, no up or down, no four directions — it is empty, and there is nowhere it is not, and nothing it does not hold. |
| 2 | God (신훈, 神訓) | 51 characters | God is in the highest place of all, with great virtue, great wisdom, and great power; brings forth the heavens, governs countless worlds, and makes all things without leaving out a single speck of dust — bright and numinous, beyond naming or measuring. And then: seek the seed in your own nature — it has already come down and is present in you. |
| 3 | The Heavenly Palace (천궁훈, 天宮訓) | 40 characters | Heaven is God's country, and it has a palace: steps made of every goodness, gates made of every virtue. Only the one who has opened their nature and completed the work may enter. |
| 4 | The World (세계훈, 世界訓) | 72 characters | Look at the countless stars, large and small, bright and dark. One God made these many worlds. The earth was formed, sea and land took shape, warmth and light were breathed over it, and living things multiplied. |
| 5 | Truth (진리훈, 眞理訓) | 167 characters | The chapter about you: three truths, three delusions, three roads, eighteen states — and the way back. |
Notice two things about that table before we go on.
First, the Truth Chapter is almost half the scripture — 167 of 366 characters. Whatever else this text is doing, it spends most of its length on the human being.
Second, look at chapter 3 again. The gate of the heavenly palace is described with the exact phrase that ends the Truth Chapter: seongtong gongwan (성통공완, 性通功完) — the nature opened, and the work completed. The scripture states the destination in chapter 3 and then, in chapter 5, hands you the road. That is not an accident of arrangement. It is the design.
Where does the Samil Singo come from?
This is the part where confident answers are easy to find and hard to verify, so let us slow down and keep two questions apart.
What the text says about itself. The scripture opens as a speech. Its first words are the ruler addressing the assembled multitude — "You, the gathered ones, listen" — and everything that follows is delivered as instruction spoken aloud to a community, not as an essay composed at a desk. That framing matters for how it reads: short lines, plain images, nothing to look up. It was made to be heard and remembered.
What tradition holds. Traditional accounts place the Samil Singo among Korea's most ancient teachings, handed down alongside the Cheonbugyeong from the earliest days of the tradition and preserved through a long line of transmission before it was fixed in the Chinese characters we read now.
What can be documented. The versions circulating today reached most modern readers through collections published in the modern era, and different transmitted editions differ in small ways — including in what the five chapters are named. How old the wording itself is, and exactly how it travelled, is debated, and this article does not pretend to settle it.
Why say all this out loud? Because a wisdom text does not need a forged birth certificate. The same honesty applies elsewhere in this tradition: the oldest record of the three seals of Dangun tells us there were three sacred gifts but never says what they were, and admitting that gap makes the reading that follows more trustworthy, not less.
So here is the position this article takes. What the text says can be examined directly, line by line, by anyone. How old it is is a separate question, still open. You are allowed to find a text meaningful while remaining uncertain about its exact age — which is, in fact, how most readers have always met it.
The translations that follow are Zexeda's commentary on the original text.
The Truth Chapter: what were you given?
The Truth Chapter opens with a gift, not a problem.
人物同受三眞 曰性命精 人全之 物偏之 "People and all things alike receive three true things. They are called seong, myeong, and jeong. People receive them whole; other things receive them partially."
Three things are called true (진, 眞) here, and they are given before anything is earned. In Korean they are 성 (性), 명 (命), and 정 (精) — the three truths, samjin (삼진, 三眞).
- Seong — your true nature. A true nature free of the division into good and evil, and so with nothing obstructing it.
- Myeong — your true life. A true knowing free of the division into clear and murky, and so with no ignorance in it.
- Jeong — your true essence. A true form free of the division into abundance and lack, and so never diminished.
Then comes the line that gives human beings their strange position in this tradition: people receive them whole; other things receive them partially. A stone, a stream, a pine tree — each carries the three truths in a leaning, partial way. A human being carries all three, complete. That is not a claim of superiority; it is a description of completeness. To receive them whole means that you are, from the beginning, a complete being — a true being.
The chapter then says something surprising about what these three actually are:
| Truth | What it is free of | Who can meet it | Verb |
|---|---|---|---|
| True nature (진성, 眞性) | good and evil | those awakened most deeply | open through it (통, 通) |
| True life (진명, 眞命) | clear and murky | those awakened to a middling degree | know it (지, 知) |
| True essence (진정, 眞精) | abundance and lack | those awakened to some degree | preserve it (보, 保) |
Read the middle column slowly, because it is easy to skim past. True nature is free of good and evil. Not "mostly good." Free of the pair entirely — prior to the sorting. True life is free of clear and murky. True essence is free of too much and too little. Each truth sits before the measurement we are used to applying.
And then the chapter names the destination in five characters, long before it has described the road:
返眞一神 "Returning to the true is becoming the one God."
Not building something. Not being awarded something. Returning. Everything after this line is an account of what we must return from.
One more thing worth noticing: the three verbs in the last column — open through, know, preserve — are not decoration. They come back later as the fruit of practice, in the three words seongtong (성통), myeongji (명지), and jeongbo (정보): the nature opened, the life known, the essence preserved. The Truth Chapter tells you at the start exactly what it will hand you at the end.
What covered it? Three delusions, three roads, eighteen states
If we were given three whole truths, why does life feel nothing like that? The chapter answers immediately, and without blame.
惟衆 迷地 三妄着根 曰心氣身 "But ordinary people lose the root and fall into confusion, and three false things take root: they are called mind, energy, and body."
The three delusions (삼망, 三妄) are not three enemies. They are three clouded versions of the three truths — and the pairing is fixed. Do not shuffle it:
| Truth given | Delusion that grew over it | What the delusion starts doing |
|---|---|---|
| Seong — true nature | Mind (심, 心) | Sorts everything into good and evil — good brings blessing, evil brings calamity |
| Myeong — true life | Energy (기, 氣) | Turns clear or murky — clear brings long life, murky an early death |
| Jeong — true essence | Body (신, 身) | Swings between abundance and lack — abundance is called noble, lack is called lowly |
Look at what each delusion does. It splits a truth into a pair, and then starts choosing between the halves. True nature had no good or evil; the mind invents the two and spends a lifetime picking. True life had no clear or murky; the energy divides and starts worrying. True essence had no abundance or lack; the body counts what it has against what it does not.
That third column is written in the plain language of its time, and it is worth reading as description rather than as a rule about health or worth. The chapter is not promising anyone a long life or threatening anyone with a short one. It is naming, in the simplest terms available, how a life feels when it is run by a divided measure.
Then the two sides meet:
眞妄對作三途 曰感息觸 轉成十八境 "The true and the false stand facing each other and make three roads. They are called feeling, breath, and contact. These roll onward and form eighteen states."
The three roads (삼도, 三途) are gam (감, 感 — feeling), sik (식, 息 — breath), and chok (촉, 觸 — contact). And they branch into the eighteen states (십팔경, 十八境), six on each road:
| Road | The six states |
|---|---|
| Feeling (감, 感) | joy (희, 喜) · fear (구, 懼) · sorrow (애, 哀) · anger (노, 怒) · craving (탐, 貪) · aversion (염, 厭) |
| Breath (식, 息) | fragrance (분, 芬) · rot (란, 爛) · cold (한, 寒) · heat (열, 熱) · dryness (진, 震) · damp (습, 濕) |
| Contact (촉, 觸) | sound (성, 聲) · color (색, 色) · smell (취, 臭) · taste (미, 味) · lust (음, 淫) · touch (저, 抵) |
The first row will feel familiar to anyone. Notice that joy is on the list alongside anger and fear. The chapter is not calling joy bad. It is saying that all six are states you get pulled along by — and a person dragged by joy is being dragged just as surely as a person dragged by anger.
The middle row is the one modern readers find strangest: fragrance and rot, cold and heat, dryness and damp. These are the qualities the breath meets — the air of a life, sweet or spoiled, freezing or stifling, parched or heavy. If the feeling road is what your heart is doing, the breath road is the atmosphere you are living inside, the one you stop noticing until it changes.
Then the chapter says what happens to a life run this way:
衆 善惡淸濁厚薄 相雜 從境途 任走 墮 生長肖病歿 苦 "Ordinary people mix good and evil, clear and murky, abundance and lack; they follow the roads and the states, running wherever they please — and fall into the suffering of birth, growth, decline, sickness, and death."
Running wherever they please. That is the picture: not villainy, just motion without a center. Chasing the pleasant six, fleeing the unpleasant six, and calling the chase a life.
What is the way back?
The chapter's last movement is short — a handful of characters — and it is the most quoted passage in Korean spirituality for a reason. It is a complete path in one sentence.
哲 止感 調息 禁觸 一意化行 返妄卽眞 發大神機 性通功完 是 "The awakened stop feeling, make the breath even, and guard contact; acting with one single intention, they turn the false back and it becomes true; great inner capacity unfolds; the nature is opened and the work completed. This is it."
Take it one step at a time.
1. Jigam (지감, 止感) — stop reactive feeling. Not feel nothing. The scripture is not asking for a numb life. It asks you to stop being carried. When an old emotion flares, pause: the train has pulled into the station, and you do not have to board it. Anyone can test this today, and the first attempt usually fails, and that is fine. The pausing itself is the practice.
2. Josik (조식, 調息) — make the breath even. Let the breath become slow, quiet, and smooth. That is all. Nothing counted, nothing forced, nothing held. An even breath is the atmosphere road settling — and it is remarkable how much of the feeling road settles with it, without being addressed at all.
3. Geumchok (금촉, 禁觸) — guard contact. Notice which sights, sounds, foods, screens, rooms, and conversations reliably stir the residue in you, and stop walking into them absentmindedly. This is not a vow of deprivation. It is the ordinary wisdom of not doing your hardest inner work in the noisiest room in the house.
4. Il-ui hwahaeng (일의화행, 一意化行) — act with one single intention. The scripture binds the three practices with this phrase, and the binding is the point. Jigam, josik, and geumchok are not three chores on a list. They are one movement — the will to stay true — expressed through feeling, through breath, and through contact at the same time.
5. Banmang jeukjin (반망즉진, 返妄卽眞) — the false, turned back, becomes true. Here is the hinge of the whole chapter, and it is worth pausing on. The delusions are not destroyed and replaced with something imported. They are turned back. The clouded mind turns back toward true nature. The murky energy turns back toward true life. The driven body turns back toward true essence. What was in the way, reversed, is the way.
6. Bal dae singi (발대신기, 發大神機) — great inner capacity unfolds. What was buried under the three delusions comes into use. The scripture states this plainly and does not elaborate, and this article will not elaborate either.
7. Seongtong gongwan (성통공완, 性通功完) — the nature opened, the work completed. The three verbs from the beginning arrive: the nature opened through, the life known, the essence preserved. And notice the second half — gongwan, the completion of work. The chapter does not end in private illumination. It ends in something finished, and work is finished out in the world.
Then the text closes with a single character: 是 — this is it. No summary, no epilogue. The road was described; the pointing finger drops.
If you are wondering what this looks like as an actual practice — what you would do on a Tuesday morning — that is exactly what the three seals of Dangun lays out: the sword that clears what covers you, the mirror that keeps the recovered true self clear through jigam, josik, and geumchok, and the bell that rings the clarity outward for the good of others. The Samil Singo gives the diagnosis and the direction. The three seals give the sequence of steps.
What does the Truth Chapter mean for me today?
You do not need to memorize 366 characters, and nothing here asks you to adopt a belief. The Truth Chapter is most useful as a way of noticing, and noticing can start on any ordinary day.
1. Name which road you are on. The next time something has hold of you, ask which of the three it came down: is this feeling (something flared inside), breath (the atmosphere you have been sitting in for three hours), or contact (something you saw, heard, ate, or scrolled)? Just naming the road takes some of its speed away. Very often the answer is the one you least suspected — a bad afternoon that felt like a feeling problem turns out to be a stale room and a screen.
2. Try the eighteen as a checklist, not a verdict. Look at the six on the feeling road and find the one that runs your week. Most people have a favorite. There is no scoring here, and no failure — the chapter does not call you bad for having a favorite. It simply says that being dragged is being dragged.
3. Let "turned back, becomes true" change your relationship to your worst part. This is the gentlest thing the Truth Chapter has to offer, and it is easy to miss. Your restless mind is not an intruder; it is your true nature, clouded. Your murky energy is your true life, clouded. The thing you have been fighting is made of the thing you have been looking for. That does not make the work shorter. It does make it less lonely.
4. Keep one breath honest. Of the three practices, josik is the one available at every moment of a day — in a queue, in traffic, before a hard sentence. Slow, quiet, smooth. That is the entire instruction.
And if you want the ground under all of this — why a covered brightness can be recovered at all — the Cheonbugyeong supplies it in one line: "the use changes, but the root does not move" (用變不動本). The surface of a life never holds still. The root never moves. The Samil Singo simply tells you what grew over the root, and in what order to take it off.

Key takeaways
- The Samil Singo (삼일신고, 三一神誥) is a Korean scripture of 366 characters in five chapters — Heaven (천훈), God (신훈), the Heavenly Palace (천궁훈), the World (세계훈), and Truth (진리훈). Its name means the divine teaching of the three and the one.
- Its fifth and longest chapter, the Truth Chapter (진리훈, 眞理訓, 167 characters), is the chapter about human beings, and it moves in one unbroken line of thought.
- Three truths were given: seong (true nature), myeong (true life), jeong (true essence). People receive them whole; other things receive them partially. Returning to the true is becoming the one God (返眞一神).
- Three delusions grew over them: mind over nature, energy over life, body over essence — each splitting a truth into a pair and then choosing between the halves.
- The three delusions open three roads — feeling, breath, contact — which branch into eighteen states, six on each road, and a life spent chasing them ends in the suffering of birth, growth, decline, sickness, and death.
- The way back is jigam (stop reactive feeling), josik (make the breath even), and geumchok (guard contact), bound together as one single intention.
- The hinge of the chapter is 返妄卽眞 — the false, turned back, becomes true. Nothing is imported; what was in the way, reversed, is the way.
- The road ends at seongtong gongwan — the nature opened and the work completed — the same phrase the scripture uses, in chapter 3, for the gate of the heavenly palace.
- Like the Cheonbugyeong, its age and transmission are debated while its meaning can be examined directly. Keeping those two questions apart is the honest way to read it.
