I Ching Hexagrams Guide: Trigrams, Lines, and Change

Answer First

An I Ching hexagram is a six-line figure made from an upper and lower trigram. Each line is broken or unbroken, giving sixty-four possible figures. To identify one correctly, record lines from the bottom upward, distinguish stable from changing lines, and use a named edition instead of relying on a number or keyword alone.

Definition: This I Ching hexagrams guide uses “hexagram” for one six-line pattern in the Yijing, or Book of Changes, together with its received number, name, text, and line positions.

Why: A number, an English title, a diagram, and a prediction are not the same thing. Keeping them separate makes a reading easier to check across books and prevents a translation choice from being presented as fixed fact.

Example: A casting recorded as solid, broken, broken, solid, broken, solid from bottom to top is not preserved if someone redraws the list from top to bottom. The same six marks appear on paper, but the identified upper and lower trigrams change.

This is cultural and interpretive material. The Yijing has a long textual and philosophical history; a hexagram does not provide a scientifically validated forecast for health, money, safety, law, or relationships. The I Ching complete guide covers casting and responsible consultation at a broader level.

Key Facts

• A trigram has three positions. A hexagram has six positions and can be split into a lower trigram and an upper trigram.
• Two possible line states across six positions produce 2⁶, or 64, possible diagrams.
• The received King Wen sequence numbers the figures from 1 to 64. Other arrangements can display the same figures in a different order.
• Lines are conventionally counted upward: first at the bottom, sixth at the top.
• “Changing line” describes a line marked to transform into its opposite in a derived figure. The original and derived figures should both be retained.
• Chinese titles can have several defensible English renderings. “Qian” may appear as The Creative, Force, Heaven, or transliterated Qian, depending on the edition.
• Judgment, Image, line statements, later commentaries, translator notes, and a reader’s application are distinct layers.
• The hexagram figure is reproducible when the six line values and order are saved. The interpretation is method-dependent.
• One-word websites often remove the conditions, images, and tensions that make the source text richer than a keyword deck.
• Unknown is a responsible answer when the casting procedure, line order, edition, or changing-line rule is missing.

From Trigrams to Sixty-Four Hexagrams

Start with the smallest unit. An unbroken line is conventionally associated with yang and a broken line with yin. Three positions create eight combinations: Qian, Dui, Li, Zhen, Xun, Kan, Gen, and Kun. The exact English gloss varies, but familiar images include heaven, lake, fire, thunder, wind or wood, water, mountain, and earth.

Stack one trigram above another. Eight possible lower trigrams multiplied by eight possible upper trigrams gives sixty-four combinations. This arithmetic explains the complete set without requiring a mystical claim. It also provides a simple quality check: a “complete” chart with 62 or 65 figures is incomplete or mislabeled.

The Chinese Text Project Book of Changes, accessed 2026 presents the received text and lets readers move among figures and commentarial material. The Stanford Encyclopedia of Philosophy discussion of Chinese philosophy of change, revised 2022 places the text within changing traditions of divination, cosmology, ethics, and philosophy. These sources are more useful for history than a page that assigns each figure one mood word.

An I Ching hexagrams guide should also distinguish logical completeness from historical arrangement. Binary combinations can be ordered in many ways. The familiar numbering used in most English editions is a received sequence, not a mathematical necessity. If an app lists Hexagram 29 as Kan and another grid puts the Kan-over-Kan pattern in a different cell, the diagram may still be the same while the display order differs.

Use this I Ching hexagrams guide as an index to structure, then use a complete named translation for the text itself.

How to Read the Six Positions

Write a hexagram like a small building: first line at the foundation, sixth at the top. This bottom-up order is easy to forget because English prose normally begins at the top of a page.

Position	Conventional label	Recording question
6, top	uppermost line	Is this line stable or changing?
5	fifth line	What mark was actually cast?
4	fourth line	Does the upper trigram begin here?
3	third line	Does the lower trigram end here?
2	second line	Was broken versus unbroken copied correctly?
1, bottom	beginning line	Did the worksheet start here?

The lower trigram consists of lines 1 through 3. The upper trigram consists of lines 4 through 6. A nuclear-trigram analysis, used in some interpretive traditions, extracts overlapping inner lines, but that is an additional method. Do not quietly substitute it for the visible upper and lower trigrams.

Line position and line type are different facts. “Second line” tells you where it sits; “broken line” tells you its form; “changing line” tells you how the casting marked it; “second nine” or “second six” is language used in many translations for a yang or yin line statement at that position. A careful note keeps all four apart.

A Compact Reference to the Received Sequence

The table below is an index, not a set of predictions. English names are short working glosses; consult a full edition for the judgment, image, line statements, and translator notes.

No.	Pinyin	Working gloss	No.	Pinyin	Working gloss
1	Qian	Force / Creative	33	Dun	Retreat
2	Kun	Field / Receptive	34	Da Zhuang	Great Power
3	Zhun	Sprouting Difficulty	35	Jin	Advancing
4	Meng	Youthful Folly	36	Ming Yi	Darkening of Light
5	Xu	Waiting	37	Jia Ren	The Family
6	Song	Conflict	38	Kui	Opposition
7	Shi	The Army	39	Jian	Obstruction
8	Bi	Holding Together	40	Xie	Release
9	Xiao Xu	Small Restraint	41	Sun	Decrease
10	Lu	Treading	42	Yi	Increase
11	Tai	Peace	43	Guai	Breakthrough
12	Pi	Standstill	44	Gou	Encountering
13	Tong Ren	Fellowship	45	Cui	Gathering
14	Da You	Great Possession	46	Sheng	Pushing Upward
15	Qian	Modesty	47	Kun	Confinement
16	Yu	Enthusiasm	48	Jing	The Well

19	Lin	Approach	51	Zhen	Thunder / Arousing
20	Guan	Viewing	52	Gen	Mountain / Keeping Still
21	Shi He	Biting Through	53	Jian	Gradual Development
22	Bi	Adornment	54	Gui Mei	Marrying Maiden
23	Bo	Splitting Apart	55	Feng	Abundance
24	Fu	Return	56	Lu	The Traveler
25	Wu Wang	Without Entanglement	57	Xun	Wind / Gentle
26	Da Xu	Great Restraint	58	Dui	Lake / Joyous
27	Yi	Nourishment	59	Huan	Dispersion
28	Da Guo	Great Exceeding	60	Jie	Limitation
29	Kan	Repeated Water	61	Zhong Fu	Inner Truth
30	Li	Clinging Fire	62	Xiao Guo	Small Exceeding
31	Xian	Influence	63	Ji Ji	Already Across
32	Heng	Duration	64	Wei Ji	Not Yet Across

Several names repeat in romanization while using different Chinese characters or contexts. Qian appears as the name of Hexagram 1 and as the common romanization of Hexagram 15’s “modesty” title, but they are not the same written word. Kun similarly appears in different titles. A search result that strips tone marks and characters can make this look like an error.

The list is a navigation aid. It is not a substitute for the text. Hexagram 47, for example, is not exhausted by the word “confinement.” The judgment, image, individual line statements, historical glosses, and the reader’s situation create layers that a two-word card omits.

Number, Name, Diagram, and Text Are Separate Fields

When people say “I got 24,” they may mean at least four things:

1. the diagram associated with number 24 in the King Wen sequence;
2. the Chinese title Fu;
3. an English translation such as Return;
4. a modern author’s short interpretation.

These fields often travel together, but only the diagram is fully recoverable from the six line forms. A number depends on sequence. A title depends on the received textual tradition. An English gloss depends on translation. A personal application depends on question and context.

This separation helps when comparing editions. Make a table with columns for figure, sequence number, Chinese or pinyin title, translator’s title, judgment summary, changing lines, and your notes. If two books use “Return” and “Turning Point,” you can see that both refer to Fu rather than treating them as separate hexagrams.

An I Ching hexagrams guide is most dependable when it shows the line figure beside every English title.

John Minford, Richard Wilhelm with Cary Baynes, James Legge, Richard Rutt, Edward Shaughnessy, and other translators make different historical and literary choices. A beginner does not need to declare a winner. Record the edition, read its introduction, and compare one passage closely before combining language from several books.

Changing Lines and the Relating Figure

A static six-line diagram records yin and yang form. Many casting systems also mark a line as stable or changing. A changing unbroken line becomes broken in the relating figure; a changing broken line becomes unbroken. Stable lines keep their form.

Suppose the original figure has one changing line at position 2. Copy all six positions into a second column, switch only line 2, and then identify the new upper and lower trigrams. Do not redraw from memory. The guide to recording I Ching changing lines provides a detailed worksheet process.

With several changing lines, the mechanical transformation is still straightforward: switch each marked line. Interpretation is less uniform. One book may emphasize all changing line statements, another may prioritize one by a stated rule, and another may read the original and relating judgments differently. The honest note is “interpretation rule: edition X, page Y,” not “the I Ching always says to use only this line.”

The relating figure is also easy to overstate. It may be read as movement, tendency, context, or a second perspective depending on the approach. Calling it a guaranteed future event goes beyond the recorded mechanics.

How Casting Methods Affect the Record

Coins, yarrow stalks, apps, dice, and card-like tools can all produce line values, but they do not necessarily produce them with the same process or probability distribution. A complete record names the method.

For three fair coins under a common convention, each coin receives a value of 2 or 3. The sum is 6, 7, 8, or 9. There are eight equally likely coin combinations: one totals 6, three total 7, three total 8, and one totals 9. That gives probabilities of 1/8, 3/8, 3/8, and 1/8 if the coins are fair and the convention is followed.

The traditional yarrow-stalk procedure involves repeated divisions and remainders. Published reconstructions and simplified teaching methods should be identified rather than assumed identical. An app should disclose its algorithm if you want to compare results at that level. “Random” on a screen is not enough information to reconstruct the line-generation rule.

The comparison of I Ching and Tarot explains why method, physical process, and recordability matter when choosing a reflective system.

The Hexagram Evidence Ladder

This I Ching hexagrams guide uses a five-rung evidence ladder. Move upward only when the lower rung is preserved.

Rung	Record	Example	Status
1	physical or digital output	coin totals: 7, 8, 7, 9, 8, 7	reproducible if method is known
2	line diagram	six lines drawn bottom to top	reproducible from totals
3	text identity	number, pinyin name, edition	checkable in that edition
4	interpretation	“line 4 raises a question about timing”	method-dependent
5	action and review	“ask for the deadline before agreeing”	evaluated against real events

Problems occur when a reading begins at rung 4 and invents rungs 1 through 3 later. “You received Abundance with a hidden warning” is impossible to check if the six lines, changing marks, and edition are absent.

The evidence ladder turns an I Ching hexagrams guide from a list of keywords into a record that another reader can audit.

A strong record also separates observation from interpretation. “Line 4 changed” is observation. “The project will fail in April” is a predictive claim. “This prompts me to check whether the delivery date is realistic” is a reflective action. Only the last can be assessed through ordinary project evidence without granting the diagram causal power.

A Worked Identification Example

Suppose a three-coin session produces these totals in order: 8, 7, 8, 9, 7, 8. The first total belongs to line 1 at the bottom.

Position	Total	Original form	Changes?	Relating form
6	8	broken	no	broken
5	7	solid	no	solid
4	9	solid	yes	broken
3	8	broken	no	broken
2	7	solid	no	solid
1	8	broken	no	broken

The original lower trigram is broken-solid-broken, Kan. The original upper trigram is solid-solid-broken when read from its own bottom at line 4, giving Dui. The relating lower trigram remains Kan; the relating upper trigram becomes broken-solid-broken, also Kan.

Now verify the diagram in the chosen edition. Write the identified number and name after checking, not before. Then copy the exact page references for the original judgment, the fourth line, and the relating figure. If a website and book disagree, compare their line order and trigram matrix before assuming one title is wrong.

Finally, write a bounded application: “The line text makes me examine whether I am speaking before the evidence is ready. Before Friday’s meeting, I will list which figures are confirmed and which are estimates.” This turns a symbolic prompt into a concrete review without claiming that the hexagram causes the meeting outcome.

That worked example is the minimum information an I Ching hexagrams guide should preserve when it demonstrates a reading.

Expert Explanation: Why Translation Changes the Reading

The Yijing’s textual layers are compact, old, and surrounded by a large commentarial tradition. Translation requires choices about grammar, historical usage, ritual context, received commentaries, and readable English. Richard Smith’s Oxford scholarship treats the Yijing as a text with a long life in China and beyond; the Oxford Academic chapter “What Is the Yijing?”, published 2022 is a useful starting point for that layered identity.

Scholars also analyze trigrams and hexagrams as part of the text’s intellectual history. The Princeton University Press chapter “The Trigrams and the Hexagrams,” published 2019 provides a scholarly route beyond keyword lists.

For a practical reader, translation differences mean three things. First, cite the edition. Second, quote sparingly and keep the surrounding line or judgment visible. Third, distinguish the translator’s note from the received text. A modern paragraph about office politics may be insightful, but it is an application, not the ancient wording.

Common Identification Errors

Drawing from the top down

This reverses line positions and can change both trigrams. Put “line 1 = bottom” at the top of every blank worksheet.

Losing the changing marks

A plain broken or solid diagram does not show which lines changed. Save totals such as 6, 7, 8, and 9, or use another explicit notation.

Treating a Unicode glyph as the whole record

A hexagram character preserves the static figure, but not the question, method, changing status, edition, date, or interpretation.

Mixing several editions mid-sentence

A reader copies one title from a website, a judgment from one translation, and a line rule from another, then presents the combination as one source. Keep citations beside each borrowed layer.

Asking the result to make a consequential decision

Use qualified people and direct evidence for medical, legal, financial, safety, and major relationship decisions. A hexagram may prompt questions; it does not carry responsibility for the choice.

Key Takeaways

• A hexagram has six lines, counted from bottom to top, and contains a lower and upper trigram.
• Sixty-four figures arise from the complete set of six binary positions.
• Number, name, diagram, text, commentary, translation, and personal application are separate fields.
• Save the original line values before identifying the figure.
• Preserve changing marks and derive the relating figure by switching only those lines.
• State the casting method and edition so another reader can reconstruct the process.
• Use the Hexagram Evidence Ladder to keep output, identity, interpretation, and action distinct.
• Treat the Yijing as a cultural and reflective tradition, not a validated forecasting system.

FAQ

What is an I Ching hexagram?

It is a six-line figure made from broken and unbroken lines. Lines 1 through 3 form the lower trigram; lines 4 through 6 form the upper trigram. One figure is one of sixty-four possible patterns.

Why are the lines read from the bottom up?

That is the conventional order used to number line positions in the received tradition. Starting at the top reverses the positions and may identify a different hexagram.

What is the difference between a trigram and a hexagram?

A trigram has three lines and eight possible patterns. A hexagram stacks two trigrams into six lines, producing sixty-four patterns and connecting with a larger set of judgment and line texts.

Do changing lines create a second hexagram?

Common consultation methods switch every marked changing line to its opposite, producing a relating figure. How the two figures and several line statements are interpreted depends on the edition or lineage.
