The Ten Wings of I Ching: Understanding Confucian Commentary

You open any modern translation of the I Ching and find far more than 64 hexagram descriptions. You encounter philosophical essays on the nature of change, detailed explanations of trigram symbolism, and commentary that transforms simple divination into profound wisdom literature.

These additions are the Ten Wings, a collection of commentaries traditionally attributed to Confucius that expanded the I Ching from a fortune-telling manual into one of the foundational texts of Chinese philosophy. Understanding the Ten Wings transforms your relationship with the Book of Changes, revealing layers of meaning that the core hexagram texts only hint at.

Whether you use the I Ching for divination, philosophical study, or personal development, knowing what the Ten Wings contain and why they matter deepens every reading.

What Are the Ten Wings?

The Ten Wings (Shi Yi) are ten sections of commentary and explanation appended to the original I Ching text. The name "wings" suggests they help the core text fly, lifting it from earthbound fortune-telling to soaring philosophy.

The original I Ching likely consisted only of hexagram names, brief judgments, and line texts. These cryptic fragments required interpretation. Over centuries, scholars added explanatory material that eventually crystallized into the Ten Wings during the Warring States period (475-221 BCE).

Tradition credits Confucius himself with authoring these commentaries, though modern scholarship suggests multiple authors across several generations. Regardless of authorship, the Ten Wings bear the stamp of Confucian philosophy, emphasizing moral cultivation, social harmony, and the relationship between cosmic patterns and human conduct.

The Ten Wings Identified

The ten sections group into seven distinct works, with some works divided into two parts that count separately among the ten.

1-2. The Tuan Zhuan (Commentary on the Judgments)

The Tuan Zhuan explains the brief judgment text that accompanies each hexagram. Where the original judgment might simply say "Success. Perseverance furthers," the Tuan Zhuan explains why success comes, what the hexagram structure reveals, and how the hexagram relates to natural and moral principles.

This commentary appears in two parts, one for hexagrams 1-30 and another for hexagrams 31-64, counting as Wings One and Two.

Example: For Hexagram 1, The Creative, the original judgment is brief. The Tuan Zhuan expands: "Great indeed is the sublimity of the Creative, to which all beings owe their beginning and which permeates all heaven." This transforms a divination verdict into cosmological teaching.

3-4. The Xiang Zhuan (Commentary on the Images)

The Xiang Zhuan provides two types of commentary. The Great Image (Da Xiang) explains the symbolism of the two trigrams that compose each hexagram and draws moral lessons from their combination. The Small Image (Xiao Xiang) comments on each individual line text.

Like the Tuan Zhuan, this commentary appears in two parts counting as Wings Three and Four.

Example: The Great Image for Hexagram 11, Peace, reads: "Heaven and earth unite: the image of Peace. Thus the ruler divides and completes the course of heaven and earth." The imagery of trigrams combining becomes guidance for how leaders should act.

5-6. The Xi Ci Zhuan (Great Commentary)

Also called the Great Treatise or Appended Statements, the Xi Ci Zhuan is the most philosophical of the Ten Wings. Rather than commenting on specific hexagrams, it discusses the I Ching system as a whole, explaining how the oracle works, why change operates as it does, and what the Book of Changes reveals about reality itself.

This substantial work appears in two parts, counting as Wings Five and Six. Many of the most famous quotations attributed to the I Ching actually come from these treatises.

Famous passages include:

• "The Book of Changes is vast and great... It encompasses everything."
• "What is above form is called the Tao. What is within form is called tools."
• "The alternation of yin and yang is called the Tao."

7. The Wen Yan (Commentary on the Words of the Text)

The Wen Yan provides detailed commentary specifically on the first two hexagrams, The Creative (Hexagram 1) and The Receptive (Hexagram 2). These hexagrams represent pure yang and pure yin, the fundamental polarities underlying all other hexagrams.

Because these hexagrams embody cosmic principles in their purest form, they receive special extended treatment. The Wen Yan explores the meaning of each line in depth, connecting divination imagery to moral philosophy.

8. The Shuo Gua (Discussion of the Trigrams)

The Shuo Gua focuses specifically on the eight trigrams rather than the 64 hexagrams. It explains the origins and meanings of each trigram, their family relationships (Heaven as father, Earth as mother, etc.), their directional associations, and their correspondences to natural phenomena, body parts, animals, and qualities.

This Wing provides essential background for understanding how trigrams combine to form hexagram meanings. Anyone studying the I Ching systematically needs the Shuo Gua material.

9. The Xu Gua (Sequence of the Hexagrams)

The Xu Gua explains why the 64 hexagrams appear in their traditional order. Rather than arbitrary arrangement, the sequence reflects a logical progression that the Xu Gua makes explicit.

For example, after Hexagram 3 (Difficulty at the Beginning) comes Hexagram 4 (Youthful Folly). The Xu Gua explains: "When things begin, there is necessarily confusion. Hence there follows Youthful Folly. Folly means youth and immaturity." Each transition receives similar explanation, revealing narrative logic in the hexagram order.

10. The Za Gua (Miscellaneous Notes on the Hexagrams)

The Za Gua offers brief, often paired characterizations of the hexagrams. Unlike the sequential logic of the Xu Gua, the Za Gua groups hexagrams by relationship, often pairing hexagrams that are inversions or opposites of each other.

Examples:

• "The Creative is strong. The Receptive is yielding."
• "Peace and Standstill are the converse of each other."
• "Loss and Gain are the beginning of their rise and fall."

These terse statements function as mnemonic aids for grasping hexagram essences quickly.

Why the Ten Wings Matter

They Transform Divination Into Philosophy

The original I Ching hexagram texts are cryptic and oriented toward specific predictions. The Ten Wings reframe these texts as expressions of universal principles. What was "The dragon appears in the field" becomes a teaching about timing, virtue, and the relationship between inner development and outer manifestation.

This transformation places the I Ching alongside the Tao Te Ching and Analects as foundational Chinese philosophy rather than mere fortune-telling.

They Provide Interpretive Framework

Without the Ten Wings, interpreting hexagrams requires intuition and guesswork. The Wings provide systematic frameworks: trigram meanings, line position significance, structural relationships between hexagrams, and philosophical principles that guide interpretation.

Even if you never read the Ten Wings directly, their concepts permeate every modern I Ching translation you use.

They Connect Human and Cosmic Order

Confucian philosophy emphasizes that human society should mirror cosmic patterns. The Ten Wings make this connection explicit, showing how hexagram dynamics apply to personal conduct, family relationships, governance, and moral cultivation.

When the Great Image says "The superior person acts accordingly," it invites you to align personal behavior with cosmic principle. This moral dimension distinguishes Chinese divination from mere prediction.

They Enable Deeper Reading

Advanced I Ching practice draws heavily on Ten Wings concepts. Understanding nuclear hexagrams, hexagram pairs and inversions, the Earlier and Later Heaven trigram arrangements, and the philosophical significance of changing lines all depend on Ten Wings teachings.

Without this material, I Ching reading remains at surface level.

Confucius and the I Ching

Tradition holds that Confucius loved the I Ching so deeply that he wore out the leather straps binding his copy three times. Whether historical or legend, this image captures the devotion Chinese culture has accorded this relationship.

The Analects contains a passage where Confucius says: "If years were added to my life, I would give fifty to the study of the I Ching, and might then escape falling into great errors." This statement places the I Ching at the center of moral development.

Whether Confucius actually wrote the Ten Wings remains debated. Linguistic analysis suggests multiple authors and compilation over generations. But the philosophical orientation is unmistakably Confucian, emphasizing:

• Moral self-cultivation over fatalistic prediction
• Harmonious relationships between individuals and society
• Alignment of human action with natural patterns
• The superior person as an ideal of virtuous conduct
• Change as constant but navigable through wisdom

How the Ten Wings Appear in Modern Translations

Different I Ching translations handle Ten Wings material differently:

Integrated Translations

Wilhelm-Baynes and many popular translations weave Ten Wings commentary directly into hexagram discussions. When you read about a hexagram, you receive the original text plus Tuan Zhuan plus Xiang Zhuan explanations seamlessly combined.

Advantage: Richer, more comprehensible hexagram descriptions.
Disadvantage: Harder to distinguish original text from later commentary.

Separated Translations

Academic translations often present the Ten Wings as distinct sections, allowing you to read commentary separately from core hexagram texts.

Advantage: Scholarly precision about what is original versus added.
Disadvantage: Less accessible for practical divination use.

Excerpted Translations

Some translations include only selected Ten Wings material, typically the Tuan Zhuan and Xiang Zhuan for each hexagram while omitting the more philosophical treatises.

Advantage: Practical focus without overwhelming detail.
Disadvantage: Misses the deeper philosophical dimensions.

Working With Ten Wings Concepts

You do not need to read the Ten Wings directly to benefit from them. Their concepts inform how you already work with the I Ching:

When You Consider Trigram Meanings

Every time you think about Heaven meaning creative power or Lake meaning joy, you are using Shuo Gua material. The trigram associations that seem fundamental to the I Ching come from the Ten Wings.

When You Read the Image Commentary

The passage in hexagram descriptions that says "The image of [hexagram name]" followed by guidance for "the superior person" comes directly from the Xiang Zhuan. This is Ten Wings material.

When You Consider Line Positions

The understanding that line 5 represents the ruler position, or that lines 2 and 5 are central and favorable, derives from Ten Wings analysis. These structural insights inform every line interpretation.

When You Reflect on Change Itself

The philosophical framework that treats change as constant, yin-yang alternation as cosmic principle, and the Book of Changes as a mirror of reality, all this comes from the Xi Ci Zhuan, the Great Commentary.
