How to read the I Ching

The I Ching (易經, Yijing, "Book of Changes") looks forbidding: sixty-four six-line figures, each with a cluster of terse ancient sentences and a layer of commentary. In practice, reading it is a small set of habits. This guide walks through them in the order you meet them, from the figure itself to the texts, using Hexagram 3, Zhun as the running example. Every hexagram's full text is in our reading room.

1. The figure: six lines, read from the bottom

A hexagram (卦, gua) is six stacked lines. A solid line is yang (陽); a broken line is yin (陰). Lines are counted from the bottom up: the first line (初) is the lowest, the sixth (上) the top. The convention mirrors growth — a situation begins at the bottom and develops upward.

Each hexagram is also two three-line figures, the trigrams (八卦, bagua): a lower trigram (lines 1–3) and an upper one (lines 4–6). Zhun is ☵ Kan (water) above ☳ Zhen (thunder): "thunder under water", a sprout pushing through hard ground. Learning the eight trigrams is the fastest way to make the sixty-four feel familiar, because the picture they form is usually the first key to the meaning.

2. The name and the Judgment

Each hexagram has a one- or two-character name (屯, zhun, "sprouting / difficulty at the beginning") and a short Judgment (卦辭, guaci) — the oldest layer of text, traditionally attributed to King Wen. It is written in a formulaic language worth learning:

• 元亨利貞 — the four qualities: yuan (originating, great), heng (success, penetrating), li (advantageous, favourable), zhen (correct and firm, persevering). "元亨利貞" is the best possible verdict; many Judgments quote only some of these.
• 吉 / 凶 — good fortune / misfortune. 悔 — regret; 吝 — humiliation or difficulty; 無咎 — no blame (a frequent, quietly positive verdict: you will not be at fault).
• 利涉大川 — "favourable to cross the great river": a good time for a significant undertaking. 利見大人 — favourable to see the great person: seek someone with authority or wisdom. 利有攸往 — favourable to have somewhere to go.

Zhun's Judgment reads: 元亨，利貞；勿用有攸往，利建侯 — great success through perseverance; do not set out anywhere yet; favourable to establish helpers. Already a complete answer: real potential, but structure before movement.

3. The Image: what to do about it

The Image (大象, daxiang) names the two trigrams' natural pictures and ends with a sentence about the superior person (君子, junzi): how a thoughtful person behaves in such a situation. For Zhun: "Clouds and thunder: the superior person brings order out of confusion." This is the most practical line in any hexagram — if you remember one sentence, remember the Image.

The Commentary on the Judgment (彖傳, tuanzhuan) explains why the Judgment says what it says, in terms of the trigrams and the position of the lines. It is helpful once you know the trigrams; skip it on a first reading if it feels dense.

4. The six line texts

Each line has its own sentence (爻辭, yaoci), traditionally attributed to the Duke of Zhou, plus a short symbolism note (小象, xiaoxiang). A line text describes what happens to someone at that stage of the situation. The lines are named by position and nature: 初九 "nine at the beginning" (a yang line in place 1), 六二 "six in the second place" (a yin line in place 2), and so on — nine means yang, six means yin.

Three habits make line texts readable:

• Place matters. The second and fifth lines are the centres of their trigrams and usually read best; the fifth is the "ruler's" place. The top line often warns of going too far.
• Correctness. Yang lines sit "correctly" in odd places (1, 3, 5), yin lines in even places (2, 4, 6). An incorrect position often explains a cautious verdict.
• Correspondence. Lines 1 and 4, 2 and 5, 3 and 6 are partners; a yin and a yang in corresponding places "respond" to each other — support from the right quarter.

5. Reading a result

When you cast a reading (by three coins or yarrow stalks), each line comes out as young or old yin or yang. Old lines are changing lines (動爻): they are about to turn into their opposite, and they are where the oracle speaks most specifically.

• No changing lines: read the Judgment and Image of the hexagram. The situation is stable; the whole picture is the answer.
• One changing line: read that line's text as the heart of the answer, within the context of the Judgment. Then look at the hexagram it changes into (之卦, the "approached" hexagram) for the direction things take.
• Several changing lines: there are traditional rules for which text takes priority; see the guide to changing lines.

The nuclear hexagram (互卦, lines 2–5 rearranged) and the opposite and inverse hexagrams give further angles on the same figure — background rather than verdict. Our guide to nuclear, inverse and opposite hexagrams explains them.

6. Which translation to read

The Chinese is compressed and ambiguous by design; translators make choices. James Legge (1882) is literal and shows the structure, with the Confucian commentaries in full — it is public domain, so it is the English we print beside every passage. Richard Wilhelm (German 1924; English by Cary Baynes, 1950) is the most-read version in the West and gives each hexagram the familiar titles ("The Creative", "Difficulty at the Beginning"); we list his titles too, so you can cross-reference. Modern scholarly translations (Richard Rutt, Edward Shaughnessy, Richard John Lynn) try to recover what the Zhou-era text meant before the commentaries. Reading two side by side is the best remedy for over-reading any one phrase. More on this in the history of the text and its translations.

7. Attitude

The classical commentaries treat the Book as a mirror rather than a fortune-telling machine. It describes a kind of time and the conduct that suits it. Ask a real question, read the whole hexagram before fixing on one phrase, and look for the sentence that describes your situation rather than the one you hoped for. Then — as the tradition says — 觀其象而玩其辭: contemplate the image and savour the words.
