Open a Saju result for the first time and the unfamiliar words can hide the eight characters themselves. Day Master, Yongsin, Ten Gods, Daeun, clash: looking up one definition often produces three more terms to search. That happens because these words are not independent labels. They belong to layers in a reading, and each layer depends on the one before it.
What this guide answers
Read 36 terms in five layers instead of memorising a list
See the chart frame first, establish the Day Master as the reference, and then read Five-Element and Ten-God relations. Yongsin and time cycles come later.
Quick answer: begin with Eight Characters, Day Master, and Five Elements
The Eight Characters are the thing being read. The Day Master is the reference used to name relationships. The Five Elements describe how those relationships generate, control, support, or redirect one another. Once those three ideas are in place, a Ten-God name such as Bigyeon or Jeongjae has a derivation, Yongsin has a question to answer, and Daeun has a natal chart over which to pass.
Starting with a favourable element or a single star can feel efficient because it produces an immediate conclusion. The cost is that the reasoning disappears. A clash means little until you know which characters meet and in what layer. Daeun is not one of the eight natal characters but a sequence of time placed over them. Yongsin is not simply whichever colour appears least in an element chart. Layering the vocabulary keeps the source of each conclusion visible.
Three distinctions to keep
The Day Master is one upper character; the Day Pillar is the complete two-character column. A Daeun section is commonly arranged in ten-year units, but its first starting age differs by calculation. A combination is not automatically good, and a clash is not automatically bad.
Layer 1 · The chart frame
The first drawer describes the shape of the input. Saju literally names four pillars, while Palja names the eight characters inside them. Each pillar contains one Heavenly Stem above one Earthly Branch. Year, month, day, and hour are therefore four coordinates, not four sealed boxes that mechanically own childhood, parents, marriage, or old age.
Civil calendar labels also need care. The Month Pillar turns at the entry time of one of the twelve sectional terms (jie, 節) that mark month boundaries, not at every one of the twenty-four solar terms or at a central term (zhongqi, 中氣). The Hour Pillar depends on the time segment and may be affected by location and day-boundary settings. Read the Stems and Branches guide, the solar-terms guide, and thebirth-time guide when those inputs are uncertain.
| Term | Working definition in this guide |
|---|---|
| Saju (Four Pillars) | The four birth-time columns: year, month, day, and hour. |
| Palja (Eight Characters) | The eight characters formed by one stem and one branch in each pillar. |
| Heavenly Stems | The ten upper signs, from Gap through Gye, used in every pillar. |
| Earthly Branches | The twelve lower signs, from Ja through Hae, also associated with the zodiac animals. |
| Year Pillar | The birth-year pair, changing at the Lichun entry time under the project's Saju calculation rather than on January 1; it is not a fixed verdict on a life stage. |
| Month Pillar | The birth-month pair set at the entry times of the twelve sectional terms (jie) that mark month boundaries; the twelve central terms (zhongqi) do not change the Month Pillar. |
| Day Pillar | The birth-day pair. It includes, but is not identical to, the Day Master. |
| Hour Pillar | The pair assigned to the birth-time segment; boundary and time-correction settings can affect it. |
Layer 2 · Reference and balance
The second drawer establishes a reference. The Day Master is the stem at the top of the Day Pillar. Other chart characters receive Ten-God names from how their elements and polarities relate to it. Yin and yang distinguish two modes within a relationship; the Five Elements describe recurring processes of generation and control. Neither is a personality score by itself.
Strong and weak Day Master are structural assessments about seasonal support, roots, and relations. They do not mean a strong-minded or weak human being. Yongsin, Huisin, and Gisin also depend on a declared interpretive method. Classical structure approaches and modern balance or climate approaches can use the same word differently. Ask which method produced the label before treating it as practical advice.
| Term | Working definition in this guide |
|---|---|
| Day Master | The stem of the Day Pillar, used as the reference point for Ten-God relationships. |
| Five Elements | Wood, Fire, Earth, Metal, and Water as a language of processes and relationships, not merely five substances. |
| Yin and Yang | A paired framework for contrasting modes such as inward/outward or receptive/active. |
| Yongsin | A useful function selected under a stated interpretive method; it is not automatically the least abundant element. |
| Huisin | An influence treated as supportive of the chosen Yongsin under that method. |
| Gisin | An influence treated as obstructive under a method; it is not a moral label or a command to avoid something. |
| Strong Day Master | A structural assessment that support for the Day Master is relatively strong, not a claim of a forceful personality. |
| Weak Day Master | A structural assessment that support for the Day Master is relatively limited, not a judgment that the person is weak. |
Layer 3 · Ten-God relationships
Checkpoint before the relationship layer
From here, read the element-and-polarity relation between the Day Master and another character, not a label attached to the character alone.
The Ten Gods are ten relationship classes, not ten supernatural people. Begin with the Day Master, ask whether the other element is the same, generated by it, controlled by it, controlling it, or generating it, and then distinguish matching from opposite polarity. Those five relations multiplied by two polarities produce ten names.
This derivation matters because a character does not carry one permanent Ten-God label. Change the Day Master and the relationship changes. A single label therefore cannot prove a profession, family event, income result, or stable personality. The Ten Gods guide works through the full relation map.
| Term | Working definition in this guide |
|---|---|
| Bigyeon (Peer) | The same element and polarity as the Day Master. |
| Geopjae (Rob Wealth) | The same element with the opposite polarity. |
| Siksin (Eating God) | What the Day Master generates, with matching polarity. |
| Sanggwan (Hurting Officer) | What the Day Master generates, with opposite polarity. |
| Pyeonjae (Indirect Wealth) | What the Day Master controls, with matching polarity. |
| Jeongjae (Direct Wealth) | What the Day Master controls, with opposite polarity. |
| Pyeongwan (Seven Killings) | What controls the Day Master with matching polarity; also called Seven Killings. |
| Jeonggwan (Direct Officer) | What controls the Day Master with opposite polarity. |
| Pyeonin (Indirect Resource) | What generates the Day Master with matching polarity. |
| Jeongin (Direct Resource) | What generates the Day Master with opposite polarity. |
Layer 4 · Passing time
The fourth drawer prevents the natal chart from being confused with passing time. Daeun forms large sections stepped from the Month Pillar in a forward or reverse direction. Seun is the pair belonging to a year, while monthly and daily cycles change at their own boundaries. These are layers placed over the natal eight characters, not replacements for them.
Saying that Daeun uses ten-year sections does not mean everyone begins the first section at age ten. Direction and starting age are calculated from birth conditions. The Daeun and Seun guideshows why two people born on the same date can receive opposite sequences and different starting ages.
| Term | Working definition in this guide |
|---|---|
| Daeun | Roughly ten-year sections stepped forward or backward from the Month Pillar; starting ages differ. |
| Seun (Annual Cycle) | The annual stem-branch flow changing at the Lichun entry time under the project's Saju calculation, not on January 1. |
| Monthly Cycle | The monthly stem-branch flow changing at the twelve sectional-term entry times, not at all twenty-four solar terms or the central terms. |
| Daily Cycle | The stem-branch pair assigned to each day. |
Layer 5 · Terms that move the structure
The last drawer names patterns that connect or disturb the structure. Generation is not a guarantee of benefit, and control is not a guarantee of harm; both can be necessary functions in a system. A combination may bind without fully transforming. A clash points to opposition and possible movement but does not schedule a particular event.
Sinsal names traditional observation markers derived from defined character relations. They may organise a question, but no single marker proves travel, romance, illness, wealth, or conflict. Use thecombinations and clashes guide to see the geometry before reading a story into it.
| Term | Working definition in this guide |
|---|---|
| Sixty Jiazi | The sixty-pair cycle made by combining the ten stems and twelve branches in order. |
| Sinsal | Traditional names and observation markers attached to specific character relations; no marker guarantees an event by itself. |
| Generation | The generating cycle: Wood to Fire to Earth to Metal to Water to Wood. |
| Control | The controlling cycle: Wood to Earth to Water to Fire to Metal to Wood; control is not automatically bad. |
| Hap (Combination) | A binding relation among characters; whether it operates or transforms requires further conditions. |
| Chung (Clash) | An opposing relation that asks about pressure and possible change, not a guaranteed event. |
Words whose meaning is not fixed across methods
A glossary should expose disagreement rather than hide it. Yongsin is the clearest example. In classical structure writing it can refer to the useful organising function associated with the Month Command. In modern strength-balancing or climate methods, readers may use it for an element selected to correct a perceived imbalance or temperature. Those are related conversations, but they are not interchangeable formulas.
Strength assessments also vary because schools weigh the Month Command, roots, exposed stems, combinations, and clashes differently. Even transformation through a combination can require different seasonal or structural conditions according to the method. When two readings disagree, first confirm the same birth data and time correction, then ask for the definition and priority rules used. That separates a calculation difference from an interpretation difference.
A five-step cheat sheet for reading your result
| Layer | Read first | Do not conclude yet |
|---|---|---|
| 1 · Chart frame | Saju, Palja, stems, branches, and the four pillars | Do not turn one pillar into a fixed life-stage verdict |
| 2 · Reference and balance | Day Master, yin-yang, Five Elements, strength, Yongsin, Huisin, and Gisin | Do not decide balance from counts or a method-free prescription |
| 3 · Ten-God relations | The ten relations from Bigyeon to Jeongin | Do not translate one relation directly into a personality or job |
| 4 · Passing time | Daeun, Seun, monthly cycles, and daily cycles | Do not convert one time marker into a guaranteed event |
| 5 · Structure in motion | Sixty Jiazi, Sinsal, generation, control, combinations, and clashes | Do not score good or bad from a relation name alone |
This sequence is reusable. Whenever a new claim appears, locate the layer from which it came and check whether it skipped an intermediate step. “A clash means I will move” jumps from a relation and a time marker to a real-world event. “Indirect Wealth means sales is my ideal career” jumps from a Day-Master relation to a job title. Restoring the missing steps turns predictions into questions that can be checked against actual circumstances.
Frequently asked questions
Do I need to memorise every Saju term?
No. Start with Eight Characters, Day Master, and Five Elements. Then look up only the Ten-God and cycle terms that actually appear in your result. Remembering the layer a term belongs to is more useful than memorising every definition at once.
How are the Day Master and Day Pillar different?
The Day Master is the Heavenly Stem at the top of the Day Pillar. The Day Pillar is the complete stem-branch pair. Ten-God relations use the Day Master, while a discussion of the full Day Pillar includes its branch as well.
Are the Ten Gods and family relations the same thing?
Not exactly. The Ten Gods are element-and-polarity relations to the Day Master. Traditional family-role language is one way those relations have been applied. Treating it as a rigid family map can fail to reflect real households, caregiving roles, gender, adoption, or chosen family.
A reason to pause while reading
If one term is translated directly into an event, job, or prohibition, check whether the relational and real-world verification steps were skipped.
Do all schools define Yongsin, Huisin, and Gisin in the same way?
No. The chosen method changes both the question and the answer. Do not reduce Yongsin to the least frequent element, or turn Gisin into a list of colours, objects, occupations, or directions that must be avoided, without first establishing the method and the limits of that application.
Are Daeun and Seun exactly ten years and one year?
Seun changes with the year, and Daeun is conventionally arranged in ten-year sections. The first Daeun starting age, however, is individually calculated. “Ten-year sections” does not mean that every person begins one on the same birthday or at age ten.
In one sentence
Conclusion
Saju terminology is not a bag of labels; it is a reading order that moves from chart structure to relations and passing time.
Open your own chart and trace the terms in order: Eight Characters, Day Master, then Five Elements and Ten Gods. The glossary should tell you what kind of statement you are reading; it should not make the decision for you.
Sources and limits
The historical outlines of the Four Pillars, Stems and Branches, Five Elements, and Yongsin were checked against the Academy of Korean Studies entries on Saju and yin-yang/Five-Element thought. The relation formulas and current labels were cross-checked against this project's calculator, knowledge data, and published deep guides. Yeonhae Japyeong and Japyeong Jinjeon are commonly cited classical sources, but this article does not present any unverified sentence as a direct translation from them.
We intentionally leave out rules that assign a pillar to an inevitable family event or life stage, identify Yongsin as the least abundant element by default, or score every combination as lucky and every clash as unlucky. This glossary explains the vocabulary of a traditional reflective practice. It is not a scientific personality test, medical guidance, financial advice, or a schedule of future events.
Mystic Universe Editorial
Authorship & review
The old metadata promised 30 terms while the legacy body actually contained 36. This rewrite pins 36 shared IDs in one ordered data source used by all three languages. Method-dependent terms such as Yongsin, strength, and transformation are labelled as such; fixed pillar-to-family or life-stage claims, least-element-equals-Yongsin rules, and good-combination/bad-clash scoring are excluded.
Frequently Asked Questions
Q.Do I need to memorise every Saju term?▾
No. Begin with Eight Characters, Day Master, and Five Elements, then look up only the Ten-God and cycle terms in your result. It is more useful to place a term in one of the five drawers—chart frame, reference and balance, Ten-God relations, passing time, or structure in motion—than to memorise the list.
Q.How are the Day Master and Day Pillar different?▾
The Day Master is the Heavenly Stem at the top of the Day Pillar. The Day Pillar is the complete stem-branch pair. Ten-God relationships use the Day Master as their reference.
Q.Are the Ten Gods and family relations the same thing?▾
Not exactly. The Ten Gods classify element-and-polarity relations to the Day Master. Traditional family-role language is one application, but it should not mechanically fix roles in a real household.
Q.Do all schools define Yongsin, Huisin, and Gisin alike?▾
No. Classical structure and modern balance or climate methods can use the same words with different priorities. Check the method before treating Yongsin as the least abundant element or Gisin as colours, objects, jobs, or directions to avoid.
Q.Are Daeun and Seun exactly ten years and one year?▾
Seun changes yearly and Daeun is conventionally arranged in ten-year sections. The first Daeun starting age is individually calculated, so ten-year sections do not mean everyone starts at age ten.
