Overview
奇門遁甲 is one of the three cosmic board divination systems (三式, sānshì) of Chinese metaphysics, alongside 大六壬 (Six Ren) and 太乙 (Grand Unity)[1][2][3]. Where 大六壬 reads the present through the twelve heavenly generals and 太乙 forecasts dynastic-scale events, 奇門遁甲 specializes in timing — selecting the optimal moment and direction for action. Its classical domain is military strategy: choosing when to advance, where to position troops, and which gate of the cosmic field offers safe passage.
The name encodes the system's core mechanism:
| Character | Meaning |
|---|---|
| 奇 (qí) | The Three Wonders — 乙, 丙, 丁 |
| 門 (mén) | The Eight Gates (八門) overlaid on the nine-palace grid |
| 遁 (dùn) | Hiding, escaping — refers to the concealment of 甲 |
| 甲 (jiǎ) | The first Heavenly Stem, which hides within the Six Instruments |
The system produces 1,080 possible chart configurations: 540 for 陽遁 (yang ascending) and 540 for 陰遁 (yin descending). Each chart layers eight categories of information onto a nine-palace grid derived from the Lo Shu (洛書) magic square, creating a dense reading of cosmic conditions at a given moment.
1. Historical Origins and Legendary Attributions
The Yellow Emperor and Chi You
The mythological origin of 奇門遁甲 is set during the Yellow Emperor's (黃帝) war against the rebel chieftain Chi You (蚩尤). According to legend, the Yellow Emperor was losing the battle until the Nine Heavens Mysterious Woman (九天玄女) descended and transmitted the methods of 遁甲 to him. His minister Feng Hou (風后) organized these teachings into a systematic framework — reducing what was originally said to comprise 1,080 formations down to a practicable art[1:1][4].
While the legend is not historical, it reflects the system's deep association with military command. The attribution to Feng Hou as recorder and systematizer appears consistently across classical sources.
《煙波釣叟歌》 — Song of the Fisherman in Misty Waves
This verse text is the most widely cited mnemonic summary of 奇門遁甲's principles. Written in heptasyllabic verse, it encodes the relationships between stems, stars, gates, and palaces in a form amenable to memorization. The poem serves as both a teaching tool and a compressed reference for practitioners constructing charts without printed tables.
Classical Foundations
The cosmological framework draws on the 《黃帝陰符經》 (Huángdì Yīnfú Jīng, Scripture of the Hidden Talisman), which establishes the metaphysical principles of cosmic timing and strategic alignment that 奇門遁甲 applies in practice[1:2].
The system's military applications are well attested in historical sources[5]. Butler documents the use of cosmic board divination in Han-dynasty military planning, where battle array schemas incorporated 遁甲 principles for determining auspicious and inauspicious positions[6]. Harper and Kalinowski provide extensive analysis of the shi (式) cosmic board as a physical instrument underlying all three 三式 methods[7][8][9]. Dunhuang manuscripts offer further evidence of the system's medieval practice and transmission[10].
Transmission to Japan
The 《日本書紀》 (Nihon Shoki) records that in 602 CE (Empress Suiko's reign), the Buddhist monk Gwalleuk (觀勒) arrived from Baekje and transmitted several Chinese arts including 遁甲 to the Japanese court[11]. This represents one of the earliest documented cross-cultural transmissions of the 三式 systems.
2. The Nine Palace Grid (九宮格)
The structural foundation of 奇門遁甲 is the nine-palace grid, derived from the Lo Shu (洛書) magic square — a 3×3 arrangement in which every row, column, and diagonal sums to 15[12]:
Each palace is associated with a trigram (八卦) and compass direction. The eight outer palaces correspond to the eight cardinal and intercardinal directions; the center palace (宮5) has no direction of its own.
Palace 5 is special. Because the center has no gate and no direction, any star, gate, or instrument that would land on palace 5 instead "borrows" (寄) to palace 2 (坤). This borrowing rule is a consistent feature across all layers of the chart.
The grid functions as a cosmological model: eight directions plus center represents the totality of space. When combined with the temporal layers (stems, stars, gates, deities), the grid becomes a map of both space and time at the moment of inquiry.
3. The Eight Layers of Information
A complete 奇門遁甲 chart stacks eight layers of symbolic information onto the nine-palace grid. Each layer provides a different category of meaning, and the interaction between layers at each palace produces the chart's reading.
Layer 1 — Three Wonders and Six Instruments (三奇六儀)
The nine non-甲 Heavenly Stems are divided into two groups:
| Group | Members | Significance |
|---|---|---|
| Six Instruments (六儀) | 戊, 己, 庚, 辛, 壬, 癸 | The six "armor bearers" within which 甲 hides |
| Three Wonders (三奇) | 乙 (日奇, Sun Wonder), 丙 (月奇, Moon Wonder), 丁 (星奇, Star Wonder) | Auspicious agents that bring favorable conditions |
These nine elements follow a fixed ordering: 戊 己 庚 辛 壬 癸 丁 丙 乙.
The mechanism that gives the system its name operates here: 甲 is the supreme stem, the commander, and a commander must not be exposed on the field. Instead, 甲 conceals itself within 戊 — the first of the six instruments. This is the "escaping 甲" (遁甲). In classical military metaphor, the general hides among his officers. The six 甲-headed sexagenary combinations (甲子, 甲戌, 甲申, 甲午, 甲辰, 甲寅) each correspond to one of the six instruments[1:3].
Layer 2 — Earth Plate (地盤)
The earth plate places the nine elements (three wonders + six instruments) onto the nine palaces. The starting palace is determined by the pattern number (局數, 1–9), and the elements proceed through the Lo Shu sequence:
- 陽遁 (yang ascending) follows the natural Lo Shu flow: 1 → 8 → 3 → 4 → 9 → 2 → 7 → 6
- 陰遁 (yin descending) reverses the sequence: 9 → 2 → 7 → 6 → 1 → 8 → 3 → 4
The earth plate is fixed for the duration of the chart — it represents the stable terrestrial conditions.
Layer 3 — Heaven Plate (天盤)
The heaven plate is a rotation of the earth plate. The rotation offset is determined by the relationship between the current hour's branch and the position of 戊 on the earth plate: specifically, the distance from 戊's home palace to the palace where the hour's instrument falls.
While the earth plate is fixed, the heaven plate rotates, modeling the dynamic relationship between heaven and earth at the moment of inquiry.
Layer 4 — Nine Stars (九星)
Nine stars are assigned to the nine palaces:
| Star | Home Palace | Name |
|---|---|---|
| 天蓬 | 1 (坎) | Heavenly Canopy |
| 天芮 | 2 (坤) | Heavenly Luxuriance |
| 天衝 | 3 (震) | Heavenly Surge |
| 天輔 | 4 (巽) | Heavenly Support |
| 天禽 | 5 (中) | Heavenly Bird |
| 天心 | 6 (乾) | Heavenly Heart |
| 天柱 | 7 (兌) | Heavenly Pillar |
| 天任 | 8 (艮) | Heavenly Responsibility |
| 天英 | 9 (離) | Heavenly Brilliance |
The stars rotate by the same offset as the heaven plate. When 天禽 (whose home is palace 5, the center) would land on the center, it borrows to palace 2 — following the same center-borrowing rule as the grid itself.
Layer 5 — Eight Gates (八門)
The eight gates are among the most important interpretive elements in the chart. They represent conditions and modes of action:
| Gate | Chinese | Home Palace | Traditional Meaning |
|---|---|---|---|
| Rest | 休門 | 1 (坎) | Recovery, dormancy, consolidation |
| Life | 生門 | 8 (艮) | Growth, new beginnings, vitality |
| Harm | 傷門 | 3 (震) | Injury, conflict, aggressive action |
| Block | 杜門 | 4 (巽) | Obstruction, concealment, hiding |
| View | 景門 | 9 (離) | Visibility, display, revelation |
| Death | 死門 | 2 (坤) | Finality, rigidity, inauspiciousness |
| Fright | 驚門 | 7 (兌) | Alarm, legal matters, shock |
| Open | 開門 | 6 (乾) | Openness, leadership, authority |
The gates rotate by the same offset as the stars and heaven plate, maintaining a consistent spatial relationship across layers.
Layer 6 — Eight Deities/Spirits (八神)
The deities differ between 陽遁 and 陰遁 charts:
| Position | 陽遁 | 陰遁 |
|---|---|---|
| 1 | 值符 (Duty Talisman) | 值符 |
| 2 | 螣蛇 (Flying Serpent) | 螣蛇 |
| 3 | 太陰 (Great Yin) | 太陰 |
| 4 | 六合 (Six Harmonies) | 六合 |
| 5 | 白虎 (White Tiger) | 勾陳 (Hook Formation) |
| 6 | 玄武 (Dark Warrior) | 朱雀 (Vermillion Bird) |
| 7 | 九地 (Nine Earths) | 九地 |
| 8 | 九天 (Nine Heavens) | 九天 |
The deities are placed starting from the palace where the 值符 star currently resides, then proceeding through the Lo Shu sequence. Unlike the other rotating layers, the deities' starting point is anchored to the 值符 star's current position rather than its home palace.
Layer 7 — Duty Star (值符) and Duty Door (值使)
The 值符 and 值使 identify which star and gate are "on duty" — the active agents for the current chart:
- 值符 (Duty Star): the star whose home palace number matches the 局數
- 值使 (Duty Door): the gate whose home palace matches the 值符's home palace
These duty elements carry special interpretive weight. The 值符 star represents the authority or commander in the situation; the 值使 door represents the agent or mechanism through which events unfold.
Layer 8 — Stem Interactions and Derived Readings
Beyond the seven structural layers, practitioners derive additional meaning from the interactions between elements at each palace: the combination of heaven and earth plate stems (格局), the relationship between stars and gates (星門 配合), and the positions of the three wonders relative to the gates and deities. These combinatorial readings constitute the interpretive art of 奇門遁甲.
4. Yang Ascending and Yin Descending (陽遁陰遁)
The solar year is divided at the solstices into two halves that determine the direction of Lo Shu traversal:
| Period | Direction | Lo Shu Sequence |
|---|---|---|
| 冬至 (Winter Solstice) → 夏至 (Summer Solstice) | 陽遁 (yang ascending) | 1 → 8 → 3 → 4 → 9 → 2 → 7 → 6 |
| 夏至 (Summer Solstice) → 冬至 (Winter Solstice) | 陰遁 (yin descending) | 9 → 2 → 7 → 6 → 1 → 8 → 3 → 4 |
This division reflects the cosmological principle that qi ascends during the yang half of the year (when daylight increases) and descends during the yin half (when daylight decreases). The Lo Shu traversal direction governs how all rotating layers — earth plate, heaven plate, stars, gates — are placed and shifted[1:4].
5. Pattern Number (局數) Determination
The pattern number (局數) determines the starting configuration of the chart. Its derivation follows a structured calendrical process:
Identify the current solar term (節氣). The Chinese solar year contains 24 solar terms, 12 of which fall in each half-year.
Determine the sub-period (元). Each solar term is divided into three 5-day periods called 上元 (upper), 中元 (middle), and 下元 (lower). These are the three origins (三元) within each term.
Look up the 局數. Each combination of solar term and sub-period maps to a pattern number from 1 to 9.
- The 陽遁 half uses 12 solar terms (冬至 through 芒種), each with 3 sub-periods
- The 陰遁 half uses 12 solar terms (夏至 through 大雪), each with 3 sub-periods
- Total: 12 × 3 × 2 = 72 possible configurations, but the values cycle through 1–9
The 局數 fixes the earth plate (which palace receives 戊 first), which in turn anchors the 值符, 值使, and all subsequent rotations. It is the single most consequential parameter in chart construction.
The 接氣 Problem
Because solar terms do not always align neatly with the 5-day sub-period boundaries, practitioners historically debated how to handle the transition between terms. The jiēqì (接氣, "connecting qi") method splits the sub-period at the exact moment the new solar term begins. The alternative zhìrùn (置閏, "intercalary placement") method inserts a bridging period. This remains a point of divergence among schools[13].
6. Two Schools: 時家奇門 vs 日家奇門
奇門遁甲 practice divides into two major schools based on the temporal unit used to construct the chart:
| School | Temporal Unit | Chart Duration | Precision |
|---|---|---|---|
| 時家奇門 (Hourly) | Double-hour (時辰) | ~2 hours (120 min) | Higher — changes 12 times per day |
| 日家奇門 (Daily) | Day stem | 1 full day | Lower — the same chart applies all day |
時家奇門 is the predominant method in contemporary practice and the focus of most classical texts. It uses the hour branch (地支) to determine the heaven plate rotation, producing a unique chart for each of the twelve double-hours in a day.
日家奇門 uses the day stem instead, yielding a coarser but simpler chart. It was historically preferred for broader strategic planning where hour-level precision was unnecessary.
Two additional variants — 年家奇門 (yearly) and 月家奇門 (monthly) — exist in the literature but are rarely practiced and have limited textual support[1:5].
7. Classical Texts
The following texts constitute the primary classical corpus for 奇門遁甲:
《遁甲演義》 — Dùnjiǎ Yǎnyì (Elaboration on Escaping Armor)
By Cheng Daosheng (程道生) of the Ming dynasty. Preserved in the 《四庫全書》 (Sìkù Quánshū, Complete Library of the Four Treasuries), this is among the most systematic classical treatments of the subject. It provides detailed tables for 局數 determination and step-by-step chart construction procedures[14].
《煙波釣叟歌》 — Yānbō Diàosǒu Gē (Song of the Fisherman in Misty Waves)
A verse-form encoding of 奇門遁甲 principles, designed for oral transmission and memorization. Despite its compact form, it contains the essential relationships between all eight layers and serves as a practitioner's quick reference.
《遁甲萬一訣》 — Dùnjiǎ Wànyī Jué (Ten-Thousand-and-One Formulas of Escaping Armor)
Attributed to the Tang-dynasty general Li Jing (李靖), though the attribution is likely pseudepigraphic. The text focuses on military applications and tactical decision-making through 遁甲 analysis.
《黃帝陰符經》 — Huángdì Yīnfú Jīng (Scripture of the Hidden Talisman)
Not exclusively a 遁甲 text, but foundational to its cosmological framework. The scripture establishes the principles of cosmic timing, the mutual conquest of the five phases, and the relationship between celestial patterns and human action that underpin the entire 三式 tradition[1:6].
8. Open Questions
Several aspects of 奇門遁甲 remain subjects of scholarly debate or require further textual verification:
| Question | Current State | Significance |
|---|---|---|
| 接氣 vs 置閏 method | Both methods are practiced; no consensus on which is "orthodox" | Affects 局數 determination at solar term boundaries — different methods can yield different charts |
| Palace 5 borrowing target | Conventionally borrows to palace 2 (坤); some texts suggest palace 8 (艮) | Would alter the position of 天禽 and any element landing on center |
| 陰遁 deity sequence | The substitution of 勾陳/朱雀 for 白虎/玄武 is standard but not universal | Some lineages use the 陽遁 sequence for both halves |
| Hour pillar vs true solar time | Classical texts use the sexagenary hour pillar; modern practice sometimes adjusts for longitude | True solar time can shift the chart by one or two hours in extreme cases |
| Authenticity of military attributions | Li Jing authorship of 《遁甲萬一訣》 is likely pseudepigraphic | Affects dating and contextualizing the military application tradition |
| Relationship between 三式 systems | The degree of shared cosmological infrastructure among 遁甲, 六壬, and 太乙 is debated | Kalinowski argues for a common shi board origin; others see independent development[15] |
| 飛盤 vs 轉盤 (flying vs rotating plate) | Two distinct methods for moving the heaven plate — regional variation | Produces structurally different charts for the same moment |
