The I Ching (Yi Jing, Book of Changes) is consulted by casting a hexagram—a six-line figure of broken and unbroken lines—using coins or yarrow stalks. Each of the 64 possible hexagrams carries a specific teaching about the situation at hand, drawn from three millennia of Chinese philosophical insight. The I Ching doesn't predict fixed outcomes; it reflects the current energy of a situation and points toward the most harmonious response.
History & Background
The I Ching—pronounced "ee ching" and meaning "Book of Changes"—is one of the oldest continuously used texts in human history. Its origins trace back to around 1000 BCE with the Western Zhou dynasty, though the foundational trigrams (the eight 3-line symbols that combine to form the 64 hexagrams) are traditionally attributed to the mythological emperor Fu Xi in approximately 2800 BCE.
King Wen, founder of the Zhou dynasty, is credited with arranging the 64 hexagrams and writing the basic judgments associated with each while imprisoned. His son, the Duke of Zhou, later added commentaries on the individual lines. Confucius (551–479 BCE) studied the I Ching so intensively in his later years that he famously wore out several copies of the bamboo strips on which it was written, and added his own philosophical commentaries—the Ten Wings—that became inseparable from the text.
The I Ching survived multiple dynasties, political upheavals, and the burning of books under the Qin dynasty (213 BCE) because it was classified as a divination text rather than a Confucian classic and thus escaped destruction. It became one of the Five Classics of Confucianism and the foundation of Chinese cosmological thought.
The I Ching entered Western consciousness primarily through the German sinologist Richard Wilhelm's 1924 translation, rendered into English by Cary Baynes in 1950. Carl Jung wrote the foreword to Baynes's translation—an encounter that shaped his concept of synchronicity. The I Ching's influence on 20th century Western thought was substantial: it informed John Cage's chance music compositions, the Beat Generation writers, Jungian psychology, and the New Age movement.
Today, dozens of translations exist, ranging from the scholarly-literal to the psychologically interpretive. The Wilhelm/Baynes translation remains the most widely referenced in the West, though more recent translations by Alfred Huang, Thomas Cleary, and Hilary Barrett offer different lenses on the same original.
The Philosophy of the I Ching
The I Ching is built on a specific worldview: reality is not static but constantly in motion, following patterns that can be perceived and worked with. The Chinese word yi (change) points to this: the text is about the nature of change itself, how things transform from one state to another, and how to align with change rather than resist it.
Central to the I Ching's philosophy are three principles:
- Change is constant. Everything in existence moves through cycles of transformation. No situation is permanent; every condition contains the seed of its successor.
- Patterns are discernible. Change is not random. It follows the interplay of two primal forces—yin (receptive, yielding, feminine) and yang (active, firm, masculine)—which combine in endlessly varied configurations. The 64 hexagrams map 64 fundamental patterns of these combinations.
- Synchronicity connects inner and outer. The randomness of the coin toss or yarrow stalk casting is not separate from the question being asked. The moment of casting is meaningful—it reflects the current energetic state of the situation, making the hexagram drawn an accurate mirror of what is present.
The I Ching does not operate through supernatural prediction. It functions as what Jung called synchronicity: a meaningful coincidence between the outer event (the random cast) and the inner reality (the questioner's situation). Whether approached religiously, philosophically, or psychologically, the I Ching's endurance across three millennia suggests that its 64 patterns do capture something real about human experience.
Understanding Hexagrams
A hexagram is a six-line figure in which each line is either unbroken (yang, solid) or broken (yin, split). The 64 possible combinations of six yin or yang lines produce 64 hexagrams, each with its own name, image, and teaching.
Each hexagram consists of two trigrams stacked on top of each other. There are 8 possible trigrams (combinations of three yin or yang lines), and their pairing produces the 64 hexagrams. The lower trigram is often called the "inner" or "nuclear" condition; the upper trigram the "outer" or "outer situation." The relationship between inner and outer conditions is one layer of hexagram interpretation.
The eight trigrams and their associations:
- ☰ Qian (Heaven): Creative, strong, father, sky
- ☷ Kun (Earth): Receptive, yielding, mother, ground
- ☳ Zhen (Thunder): Arousing, movement, eldest son, spring
- ☴ Xun (Wind/Wood): Gentle, penetrating, eldest daughter
- ☵ Kan (Water/Abyss): Dangerous, flowing, middle son
- ☲ Li (Fire/Brightness): Clinging, light, middle daughter
- ☶ Gen (Mountain): Keeping still, stopping, youngest son
- ☱ Dui (Lake/Joy): Joyous, open, youngest daughter
The Coin Method (Step by Step)
The coin method is the most widely used modern approach—quicker than yarrow stalks but still producing valid hexagrams and changing lines.
What you need: Three coins of equal size (traditionally Chinese coins with a round hole in the center, but any three matching coins work). Assign one side "yin" (broken line) with a value of 2, and the other side "yang" (solid line) with a value of 3. In most coin conventions: heads = 3, tails = 2.
- Prepare. Sit quietly. Hold your question clearly in mind—or simply hold an open, receptive attention if asking for general guidance. Some people hold the coins, focusing on the question; others place the coins in a cup and shake them.
- Cast the coins. Throw all three coins simultaneously. Add up the values (each heads = 3, each tails = 2). The possible totals are 6, 7, 8, or 9.
-
Record the line. Each total corresponds to a type of line:
- 6 (old yin: three tails): broken line (yin), with a circle: — ⊙ — (changing)
- 7 (young yang: two tails + one heads): solid line —————
- 8 (young yin: two heads + one tails): broken line — — — —
- 9 (old yang: three heads): solid line, with an X: ———X——— (changing)
- Build the hexagram from the bottom up. Cast six times. Your first cast is line 1 (bottom); your sixth cast is line 6 (top). Write each line as you cast, building upward.
- Identify the hexagram. Using a hexagram lookup table (found in any I Ching translation), identify your hexagram by its upper and lower trigrams. This is the Primary Hexagram.
- Note any changing lines (6s or 9s). If you have any 6s or 9s, you will also construct a Changed Hexagram by reversing all changing lines (yin becomes yang, yang becomes yin). This second hexagram represents where the situation is moving.
The Yarrow Stalk Method
The yarrow stalk method is the traditional Chinese approach and takes approximately 20–30 minutes for a complete hexagram. It involves repeatedly dividing 49 yarrow stalks (or other thin sticks) into groups and counting remainders to determine line values. The process is meditative and slower, which many practitioners find deepens the quality of the consultation.
Because the mathematical probabilities differ between the coin and yarrow methods, the yarrow method produces changing lines (6s and 9s) with different frequency—old yin (6) appears less often with yarrow stalks than with coins, while old yang (9) appears more often. This subtle difference in probability is considered meaningful by traditional practitioners.
For a complete yarrow stalk casting guide, Richard Wilhelm's translation includes detailed instructions, as does Hilary Barrett's I Ching: Walking Your Path, Creating Your Future.
Understanding Changing Lines
Changing lines—the 6s and 9s in your cast—are among the most important elements in an I Ching reading. They represent the most active, unstable energies in the current situation: things in motion, areas where change is specifically happening.
When you have one or more changing lines:
- Read the Primary Hexagram first (the situation as it is now)
- Read the specific texts for each changing line in your translation (each line in each hexagram has its own commentary)
- Convert all changing lines to their opposites (yin → yang, yang → yin) to create the Changed Hexagram
- Read the Changed Hexagram as where the situation is moving—what comes next if the energy of the Primary Hexagram is followed through
When you have no changing lines, the hexagram describes a relatively stable situation. The Primary Hexagram captures the current state without an immediate implied direction of change.
When you have all six changing lines, the situation is in profound flux. Some traditions have specific interpretations for this scenario; others simply read the Changed Hexagram as primary.
How to Read and Interpret a Hexagram
Interpreting the I Ching is more art than science. The text provides evocative, often archaic imagery; your task is to find the resonance between that imagery and your specific situation. A few layers of interpretation:
- The Judgment (Decision text): The core statement about the hexagram. This is King Wen's original assessment—often brief and oracular. Read it first, without over-analyzing.
- The Image: A description of the hexagram's image in nature, usually combining the images of the two trigrams. "Thunder over Water," "Mountain above Fire," etc. The Image text often offers concrete guidance about how to act.
- The Commentary (Ten Wings): Confucian philosophical elaboration on the hexagram's meaning. More philosophical and less oracular than the Judgment.
- The Line texts: Commentary on each individual line. Only read the lines that are changing in your cast. These speak specifically to what is in active transition.
- Your own resonance: What does the hexagram image evoke for you? Where does the language land? The I Ching works through symbolic resonance, not literal statement. Trust your initial response before analyzing.
After reading the hexagram, let it sit. The I Ching rarely gives obvious, literal answers—its responses are more like koan, pointing at something that requires contemplation rather than instant translation. Some of the most meaningful I Ching readings only fully clarify days or weeks later.
Formulating Your Question
The quality of an I Ching reading depends significantly on the quality of the question. Several approaches:
- Open questions work better than yes/no questions. "What is the nature of this situation?" or "What should I attend to in my relationship with X?" produces richer responses than "Should I do Y?"
- The most honest question often gets the most useful answer. The I Ching tends to reflect what is actually happening beneath the surface. The question you're slightly afraid to ask directly is often the one worth asking.
- State the situation briefly before the question. Some practitioners briefly summarize the context before asking, which helps orient the inquiry.
- General guidance consultations are valid. You don't always need a specific question. "What do I need to understand about my current situation?" or simply bringing an open, receptive attention to the casting is a legitimate approach, particularly for ongoing practice.
- Don't re-ask the same question repeatedly. If you don't like the answer, asking again doesn't produce a better result—it produces a different hexagram that may reflect your resistance to the first answer. Sit with what was received first.
Building a Regular I Ching Practice
- Daily single-hexagram practice: Cast one hexagram each morning without a specific question. Read it as "what is present today?" Over time, this builds familiarity with the hexagrams and develops the ear for I Ching symbolism.
- Journal each consultation. Record the hexagram(s) received, the question asked, your initial response, and—crucially—what actually happened in the weeks following. Reviewing these records reveals both how the I Ching works and your own patterns of interpretation.
- Read the hexagram text before looking it up. Before reaching for your translation, sit with the raw hexagram image and the trigrams. What do you notice? What associations arise? This develops genuine relationship with the symbols rather than dependence on any single interpreter's text.
- Select one hexagram per year for study. Rather than treating the I Ching as only a consultation tool, some practitioners select one hexagram per year and work with it as a contemplative object—reading all the major commentaries on it, meditating on its image, and observing where it appears in daily life.
Recommended Translations
- Wilhelm/Baynes (1950): The classic Western I Ching. Rich philosophical commentary from a Jungian perspective. Dense but rewarding. The standard academic reference.
- Hilary Barrett, I Ching: Walking Your Path, Creating Your Future (2010): Exceptionally clear, psychologically attuned, and practically focused. Particularly well-suited to contemporary practitioners.
- Alfred Huang, The Complete I Ching (1998): A Chinese master's translation that preserves classical Chinese poetic sensibility more fully than Western translations. Beautiful and authoritative.
- Thomas Cleary (various): Multiple I Ching translations from different traditional commentaries. More scholarly and less interpretive than Huang or Barrett.
- Stephen Karcher, The I Ching: The Classic Chinese Oracle of Change: A more poetic, shamanic interpretation that emphasizes the oracle's pre-Confucian roots.
What makes the I Ching different from most divination tools is the depth of its engagement with change as the fundamental nature of reality. It does not offer comfort in the form of certainty. It offers something more valuable: a way of seeing—clearly, without flinching—the nature of whatever moment you are in, and a tradition's worth of wisdom about how to move through it most harmoniously.
Consulting the I Ching honestly and consistently is a practice of attention. You learn to ask better questions. You learn to sit with ambiguous answers. You learn that what the oracle reveals about a situation is less important than what it reveals about the quality of mind with which you approach it. This is why it has endured for three thousand years.
Frequently Asked Questions
Do I need to be Taoist or Chinese to use the I Ching?
No. The I Ching has been used meaningfully by people across cultures, religions, and worldviews for centuries. Carl Jung was a Swiss Christian; the Beats were American artists. The I Ching's patterns address universal human situations, not a culturally specific cosmology. Respectful engagement with the text as a wisdom tradition is what matters.
How often should I consult the I Ching?
This is entirely personal. Some practitioners consult daily; others only at significant decision points. The main guidance from most traditions is: don't consult repeatedly about the same question hoping for a different answer, and give yourself time to receive and integrate what the oracle offered before asking again.
What if I get a hexagram that seems completely irrelevant?
This is more common early in practice. The I Ching speaks in symbolic and indirect language. What seems irrelevant often becomes clear later. Sit with the hexagram longer, read multiple commentaries, and return to it after a few days. The I Ching rewards patience.
Can I use apps or online I Ching tools?
Yes. Digital casting produces the same hexagram distribution as coin casting (approximating it mathematically). Many practitioners find the physical act of casting coins or yarrow stalks more conducive to the contemplative state the I Ching requires, but there is no inherent metaphysical reason that digital consultation cannot work. Use what helps you be genuinely present to the question.
What is the difference between I Ching and oracle cards?
Oracle cards are typically designed by individual artists and authors with specific interpretive frameworks. The I Ching is a 3,000-year-old classical text with a rigorous, complex symbolic system developed across generations of scholarship and practice. Both can be valuable divination tools, but the I Ching operates with a depth and philosophical coherence that is uniquely its own.
