Introduction
Meongri (命理學, the study of fate-theory) is not merely a form of divination. It is a hermeneutic system and human-studies tradition that East Asian scholars have cultivated for over a thousand years. This column follows the historical trajectory of Meongri to examine how this discipline took shape and evolved.
1. Prehistory: The Archetype of Fate-Reasoning (推命法) in the Tang Dynasty
The roots of Meongri reach back to the Tang dynasty (唐, 618–907). During that period, Li Xuzhong (李虛中) established a Three-Pillar Method (三柱法) that inferred a person's life pattern by centering on the Year Pillar (年柱). This approach, summarized in the Li Xuzhong Ming Shu (李虛中命書), differed from today's Saju in that it took the sexagenary pair (干支) of the year of birth as its primary subject.
The fate-reasoning of the Tang period was closer to an empirical record than to a systematic theory, yet it is regarded as the starting point of Meongri because it first articulated the premise that "one can understand a person through the sexagenary pair of the moment of birth."
2. The Birth of the Japyeong Method (子平法) in the Song Dynasty
Meongri was formally systematized in the late Northern Song (960–1127) and early Southern Song (1127–1279). The central figure was Xu Ziping (徐子平).
Xu Ziping shifted the existing Year-Pillar-centered approach to a Day-Pillar-centered method. In other words, the perspective became: "The Heavenly Stem (天干) of the day you were born is yourself." This reorientation was decisive. Fate came to be interpreted not as a trait of a collective year-cohort but from the subjective standpoint of the individual's Day Stem (日干).
Xu Ziping's method came to be known as the Japyeong Method (子平法, Ziping method) and has since served as the foundational framework of Saju-Palja (四柱八字, Four Pillars, Eight Characters) analysis, enduring to the present day.
The name "Ziping" means "the impartial one (子平)," reflecting a scholarly attitude of observing a person's life without prejudice.
3. The Ming Dynasty: The Deepening of Theory and the Compilation of Classics
During the Ming dynasty (明, 1368–1644), the Japyeong method grew more refined. Three classics were completed around this period in particular.
Japyeongjinjeon (子平眞詮) — Shen Xiaozhan (沈孝瞻) of the Qing Dynasty
This work most rigorously organizes the system of Gyeokguk (格局, pattern) and Yongsin (用神, useful god). Centering on the Month Branch (月支), it classifies the combinations of the Ten Gods (十神) and analyzes the success and failure (成敗) of a Saju logically. Its theory of patterns is the original source of today's classifications such as "Direct Officer Pattern" or "Indirect Wealth Pattern."
Gungtongbogam (窮通寶鑑) — Compiled by Yu Chuntai (余春台), Late Ming / Early Qing
This book interprets Saju from the perspective of Johu (調候, climate regulation). It emphasizes that even within the same Gyeokguk, the Five Elements required shift depending on the season of birth (month command). The concept of balancing cold, warm, dry, and damp (寒暖燥濕) originates here.
Jeokcheonsu (滴天髓) — Attributed to Jing Tu (京圖) of the Song, Annotated by Liu Bowen (劉伯溫) in Late Ming
This is the most literary and philosophical work in the Meongri tradition. As its title suggests — "the principle of heaven is as deep as a drop of essence (滴天髓)" — it discusses the clarity or turbidity, truth or falsehood (淸濁眞假) and the firm or yielding, compliant or contrary (剛柔順逆) of a Saju through metaphor. It is regarded not as a mere technical manual but as an Eastern classical essay on fate.
These three works later came to be called the Three Great Treasured Books (三大寶書) and took their place as the canon of Meongri.
4. The Qing Dynasty: Theoretical Refinement and Popular Diffusion
During the Qing dynasty (淸, 1644–1912), scholars such as Yuan Shushan (袁樹珊) and Wei Qianli (韋千里) refined the Japyeong method further. At the same time, Meongri — once the preserve of the literati — permeated deeply into the everyday life of ordinary people.
In particular, as Western modern science entered East Asia in the late Qing, Meongri branched into two streams:
- A scholarly stream — studying classical texts and reinterpreting theory
- A practical stream — used in daily decisions such as choosing auspicious dates (擇日), compatibility readings, and individual consultations
The coexistence of these two streams continues to this day.
5. The Development of Korean Meongri
Korea had already absorbed the Japyeong method during the Goryeo period. In the Joseon era, a state institution called the Gwansanggam (觀象監, Bureau of Astronomy) officially taught the field of Myeonggwahak (命課學, the study of fate-reading) alongside astronomy and geography. Myeonggwahak was a department of the Japgwa (雜科) state examination — a professionally certified specialty recognized by the state.
In the modern period, Master Dogye Park Jae-wan (陶溪 朴在玩, 1903–1992) laid the groundwork for a distinctively Korean interpretive tradition. He is regarded as the figure who independently reinterpreted the Three Great Treasured Books and provided the theoretical foundation of modern Korean Meongri.
Contemporary Korean Meongri strongly tends to integrate the Gyeokguk theory of Japyeongjinjeon, the Johu theory of Gungtongbogam, and the deep insights of Jeokcheonsu. This integrative perspective is one of the defining features of Korean Meongri.
6. What It Means to See Meongri as a "Discipline"
When we place Meongri in historical context, something becomes clear: it is not simple superstition or sorcery but a long-refined interpretive system of knowledge. At the same time, this system is different in character from a scientifically verified predictive model.
It is appropriate to understand Meongri as follows:
- A cultural heritage: a strand of East Asian intellectual history stretching over a thousand years
- An interpretive language: a symbolic system for describing human disposition and life patterns
- A tool for self-reflection: one lens for understanding oneself and others in a multidimensional way
Important life decisions must be made on the basis of guidance from qualified professionals in the relevant fields and one's own judgment. Meongri is a cultural asset that enriches, rather than replaces, that process.
Closing Thoughts
Looking back on the history of Meongri, it becomes clear that this discipline was never merely a technique for "guessing" the future. From Xu Ziping in the Song, to the Gwansanggam of Joseon, and into modern Korean Meongri, this tradition has evolved as an interpretive effort to understand the human being.
Saju Works provides analysis grounded in this historical and scholarly context, integrating the theories of the Three Great Treasured Books. We hope you will use it not as divination, but as a reference for interpretation and self-reflection.
