Pronunciation: tuàn cí

Also spelled: Tuan Ci, Tuan, Guaci, Hexagram Statement, Decision, 卦辞

Tuan (彖) means 'to decide' or 'to judge' — the authoritative pronouncement on a hexagram's overall meaning. The tuan ci (彖辞) or gua ci (卦辞, 'hexagram statement') is the first text encountered under each hexagram, assessing the situation's fundamental character and prospects.

Etymology

The character tuan (彖) has been debated for centuries. Xu Shen's Shuowen Jiezi (100 CE), the earliest systematic Chinese dictionary, glosses tuan as 'to judge the attributes of each hexagram.' The character may derive from a pictograph of a pig being divided — a reference to the practice of examining entrails for divination, suggesting that tuan originally meant to 'read' the inner nature of something by cutting it open. The association with judgment and decision crystallized in the Tuan Zhuan (Commentary on the Judgments), one of the Ten Wings, which systematically interprets each hexagram's Judgment through the structural relationship of its component trigrams. The alternative term gua ci (卦辞, 'hexagram statement') is purely descriptive — 'the words attached to the hexagram figure.' Sima Qian's Shiji attributes the composition of the Judgments to King Wen of Zhou during his imprisonment at Youli.

About Judgment Text

The Judgment text is the first and most authoritative layer of text attached to each hexagram. In the received Zhouyi, these are terse, often enigmatic pronouncements that compress an entire situation-assessment into a few characters. Hexagram 1 (Qian): '元亨利贞' — 'yuan heng li zhen' — rendered by Richard Wilhelm as 'The Creative works sublime success, furthering through perseverance.' Hexagram 47 (Kun, Oppression): '亨。贞，大人吉，无咎。有言不信' — 'Success. Perseverance. The great man brings about good fortune. No blame. When one has something to say, it is not believed.'

The four attributes that appear most frequently in the Judgments — yuan (元, sublime/great), heng (亨, success/penetrating), li (利, furthering/advantageous), and zhen (贞, perseverance/correct/divination) — form a set known as the si de (四德, four virtues). These four characters open Hexagram 1 and recur in various combinations throughout the 64 Judgments. Their interpretation has been a central preoccupation of I Ching scholarship.

Kong Yingda (574-648 CE), in his authoritative Tang dynasty commentary Zhouyi Zhengyi, interpreted the four attributes as sequential stages: yuan as the beginning of a process, heng as its successful development, li as its fruitful maturation, and zhen as its correct completion. This reading parallels the four seasons: spring (initiating), summer (growing), autumn (harvesting), winter (storing).

Cheng Yi took a more ethical reading: yuan as the fundamental goodness of a situation, heng as the smooth communication between principles, li as the fitness or appropriateness of action, and zhen as the moral rectitude needed to sustain success. For Cheng Yi, every Judgment is simultaneously a description of a situation and a prescription for conduct within it.

The philological approach of modern scholars has revealed layers of meaning invisible to traditional commentators. Edward Shaughnessy's analysis of the Mawangdui manuscript and comparison with Western Zhou bronze inscriptions shows that many Judgment texts contain allusions to specific historical events of the late Shang and early Zhou periods. The word zhen (贞), universally translated as 'perseverance' or 'correctness' since the Han dynasty, originally meant 'divination' in the oracle bone script — suggesting that the earliest layer of the Judgments were not moral instructions but divination records: 'this hexagram portends success for divination' rather than 'perseverance brings success.'

Richard Rutt's 1996 translation, informed by this philological revolution, renders the Judgments with deliberate strangeness, preserving their archaic character rather than smoothing them into coherent English. Where Wilhelm translates Hexagram 3's Judgment as 'Difficulty at the Beginning works supreme success,' Rutt translates: 'Making offerings: greatly blessed. Favorable for divination. Do not act to go anywhere. Favorable for establishing a lord.' The difference reflects not just translation philosophy but fundamentally different understandings of what the Judgments are — philosophical wisdom literature vs. Bronze Age divination records.

The Tuan Zhuan (Commentary on the Judgments), attributed to Confucius but composed c. 4th-3rd century BCE, interprets each Judgment through the hexagram's trigram structure. For Hexagram 11 (Tai, Peace): 'Heaven and earth interact, and all things communicate freely. Upper and lower interact, and their wills are in harmony.' The Commentary explains that placing Kun (earth) above Qian (heaven) creates Peace because earth's energy naturally descends while heaven's naturally rises — they move toward each other, establishing communication. The Tuan Zhuan thus provides a structural rationale for each Judgment, connecting the oracular pronouncement to the visual-mathematical logic of the hexagram figure.

Wang Bi's commentary challenged the Tuan Zhuan's approach. Rather than explaining each Judgment through trigram correspondences, Wang Bi identified the 'ruling line' of each hexagram and derived the Judgment's meaning from that line's structural position. For Wang Bi, the Judgment summarizes the hexagram's entire dynamic, which is determined by a single pivotal line rather than by the trigram pairing. His approach produced tighter, more logically coherent interpretations but required abandoning the rich correlative system of trigram-element-season-direction correspondences that Han dynasty scholars had built.

In consultation practice, the Judgment is always the first text read. When a hexagram has no changing lines, the Judgment is the entire reading — the definitive assessment of the situation. When changing lines are present, the Judgment provides the overarching framework within which the specific line texts are interpreted. The Judgment of the transformed hexagram (the second hexagram generated by the changing lines) then provides the situation's trajectory. The interplay between two Judgments — where you are and where you are heading — is the consultative heart of an I Ching reading.

Significance

The Judgment texts are the oldest continuous layer of the I Ching — the Bronze Age oracular core around which all subsequent commentary was built. They represent what the hexagram 'says' at its most fundamental level, before any interpretive tradition intervenes. Every commentary, from the Ten Wings through Wang Bi through Zhu Xi through Wilhelm, is an attempt to unpack what these compressed statements mean.

The Judgments also represent a distinctive literary form: the oracular pronouncement. Neither poetry nor prose nor legal code nor philosophical argument, the Judgment text compresses maximal meaning into minimal language. The four-character formula yuan heng li zhen has been interpreted continuously for three millennia without exhausting its significance — an achievement of compression that few texts in any tradition can match.

For practitioners, the Judgment is the anchor of every reading. Line texts provide specificity, Image texts provide counsel, commentaries provide depth — but the Judgment provides the situation's fundamental character. When everything else is unclear, the Judgment gives the definitive assessment.

Connections

Each Judgment is interpreted by the Tuan Zhuan (Commentary on the Judgments) through the structural relationship of the hexagram's component trigrams. The changing lines determine whether the Judgment alone is read or supplemented by individual line texts.

The Judgment texts' oracular compression connects them to other ancient divination traditions: the terse pronouncements of the Delphic Oracle in Greek tradition, the cryptic verses (sthalapurana) attached to Hindu temple oracles, and the condensed wisdom of runic inscriptions — all traditions that pack maximal meaning into minimal language, requiring interpretive skill to apply.

The four attributes (yuan, heng, li, zhen) that structure many Judgments parallel the four-fold classifications common across traditions: the four purusharthas of Hindu philosophy, the four cardinal virtues of Stoicism, and the wuxing's four seasonal phases (with the fifth, earth, as the implicit center).

Frequently Asked Questions

What do the four attributes yuan, heng, li, zhen mean?

These four characters — yuan (元, sublime/great/originating), heng (亨, success/penetrating/offering), li (利, furthering/advantageous/sharp), and zhen (贞, perseverance/correctness/divination) — appear in the opening Judgment of Hexagram 1 (Qian) and recur in various combinations across the 64 Judgments. Their meaning has been debated for over two thousand years. The earliest interpretation (recovered from oracle bone usage) reads zhen as 'divination' and heng as 'sacrificial offering,' making the formula a ritual assessment: 'Great offering — favorable for divination.' The Confucian tradition reinterpreted them as moral virtues: originating goodness, penetrating communication, harmonious benefit, and steadfast correctness. Kong Yingda mapped them onto the four seasons: yuan/spring (beginning), heng/summer (growth), li/autumn (harvest), zhen/winter (completion). Each interpretation is valid at its historical level — the characters' meaning evolved as the I Ching's function shifted from royal divination tool to philosophical classic.

How is the Judgment different from the Image text?

The Judgment (tuan ci or gua ci) is the oracular pronouncement attributed to King Wen — the fundamental assessment of the hexagram's situation and its prospects. It speaks in the voice of the oracle: 'Success,' 'The great man brings good fortune,' 'It does not further to cross the great water.' The Image (xiang ci), by contrast, is an interpretive text from the Ten Wings — a later commentarial addition that reads the hexagram's trigram pairing as a natural scene and draws a moral lesson. The Image always follows a two-part formula: first the natural image ('Thunder over the lake'), then the counsel ('Thus the superior person retreats into solitude to examine their heart'). The Judgment says what the situation is; the Image says what to do about it. In consultation, the Judgment is read first and provides the primary assessment. The Image is read second and provides practical counsel. When changing lines direct attention to specific line texts, the Judgment frames those line texts' meaning.

Are the Judgments predictions or advice?

This is the central interpretive question of I Ching studies, and the answer has changed across millennia. In their oldest layer — as Bronze Age divination records — the Judgments were predictions: statements about whether a proposed action would succeed or fail. 'Favorable for crossing the great water' meant a military river crossing was auspicious. 'The maiden is powerful. Do not marry this maiden' was a specific warning. The Confucian appropriation, beginning with the Ten Wings and accelerating through Wang Bi and the Neo-Confucians, reframed the Judgments as ethical counsel: descriptions of archetypal situations with guidance on how to navigate them virtuously. Modern practitioners typically hold both dimensions simultaneously. The Judgment describes the energetic pattern of a situation (predictive dimension) and implies the appropriate response (advisory dimension). 'Perseverance furthers' is both a prediction (sustained effort will succeed) and advice (keep going). The I Ching's endurance stems partly from this dual functionality — it works both as an oracle delivering specific guidance and as a wisdom text illuminating the nature of change.
