The best way to understand the I Ching is to use it. Not to read about it, not to study it theoretically, but to hold a real question, toss three coins six times, and sit with whatever hexagram arrives.
This guide walks you through exactly that process — from preparing your question to reading what you receive. By the end you will have everything you need to cast your first genuine reading today.
What You Need 準備
Remarkably little. Three coins of the same denomination — any coins will do, though many practitioners eventually choose coins that feel meaningful to them. A notebook and pen. Fifteen minutes of quiet.
That is genuinely all. No special equipment, no app, no elaborate ritual. The I Ching was consulted by farmers and emperors alike using whatever they had to hand.
Step One — Form Your Question 問題
This is the most important step and the one most beginners rush past. The quality of your question determines the quality of what you receive.
The I Ching responds best to questions about how rather than whether. Not "will this work out" but "how should I approach this situation." Not "should I take this job" but "what is the nature of this opportunity." The difference is subtle but significant — the first asks for a prediction, the second asks for understanding.
A good I Ching question is:
Genuine — something you actually care about, not a test of the system. The I Ching has a way of giving oddly literal responses to insincere questions.
Present-focused — about what is happening now and how to meet it, rather than what will happen in the distant future.
Open — leaving room for an answer you haven't anticipated. Questions that only allow yes or no responses close off most of what the hexagram might show you.
The I Ching does not answer the question you ask. It answers the question you should have asked. Learning to hold your question lightly — to receive an unexpected answer without forcing it back into your original frame — is half of what the practice teaches.

Step Two — Cast the Coins 投錢
Hold all three coins in your cupped hands. Take a moment — a genuine moment, not a perfunctory pause — to bring your question into focus. Then toss the coins onto a flat surface and record the result.
Each coin face has a value:
| Face | Value | Notes |
|---|---|---|
| Heads | 3 | Yang value — the face with the larger image or inscription |
| Tails | 2 | Yin value — the reverse face |
Add the three values together. The total will always be 6, 7, 8, or 9. Each total produces a specific type of line:
| Total | Line Type | Symbol | Moving? |
|---|---|---|---|
| 6 | Old Yin | — x — | Yes — changing to Yang |
| 7 | Young Yang | ——— | No — stable |
| 8 | Young Yin | — — | No — stable |
| 9 | Old Yang | ——— o | Yes — changing to Yin |
Toss the three coins six times, recording a line each time, building your hexagram from the bottom upward. The first toss gives you the bottom line. The sixth toss gives you the top line.
Step Three — Build Your Hexagram 成卦
Once you have six lines, you have a hexagram. A solid line (7 or 9) is Yang. A broken line (6 or 8) is Yin. Lines 6 and 9 are moving — they are in the process of changing to their opposite.
Here is an example of what a hexagram looks like, with one moving line:
Example Hexagram — Reading from a Real Casting
萃 · Hexagram 45
The Gathering. Lake above Earth. People assembling around a centre.
One moving line — Line 3. This line transforms, producing a second hexagram that shows where the situation is heading.
To identify which hexagram you have received, divide your six lines into two groups of three — the lower trigram (lines 1–3) and the upper trigram (lines 4–6). Look up both trigrams in a hexagram reference table to find your hexagram number.
Step Four — Read the Hexagram 讀卦
Open your translation — Wilhelm/Baynes or Alfred Huang — and find your hexagram. Read in this order:
The Name and Image
Before reading any words, sit with the hexagram image itself. If you received Hexagram 29 — water flowing through a gorge — what does that image say about your situation without any commentary? Let the image do its work before the words begin.
The Judgment卦辭
The Judgment is the core statement of the hexagram — a few lines that describe the situation and its essential quality. Read it slowly. Read it again. Do not rush to interpretation. What is it actually saying, stripped of any desire to make it say what you hoped?
The Great Image大象
The Great Image commentary — often one or two lines — describes how the practitioner responds to this hexagram. It is the most practical element of the reading: not what the situation is, but what it asks of you.
The Moving Lines爻辭
If you have moving lines — values of 6 or 9 — read the commentary for each one. Moving lines show where the situation is most alive, most in transition. They are the most specific and personal communication — the part of the reading most directly addressed to your particular situation.
The Relating Hexagram之卦
If you have moving lines, transform them — Yang moving lines become Yin, Yin moving lines become Yang — to produce a second hexagram. This relating hexagram shows where the situation is heading, the direction of change already underway.
Read the relating hexagram's Judgment and Image only — not its line commentaries. It describes a direction, not a fixed destination.
Step Five — Record Your Reading 記錄
This step is where most beginners stop — and where most of the practice's depth is lost.
Write down your reading in a dedicated notebook immediately after casting. Not a summary — the full record. This record is where genuine understanding develops over months and years.
The final entry — written a week later — is where the reading's meaning becomes clear. This is characteristic of genuine I Ching practice. The hexagram often makes more sense after the situation has developed than it did at the moment of casting.
What to Do When It Seems Wrong 困惑
You will receive hexagrams that seem to have nothing to do with your question. This is normal, and it is one of the practice's most important teachings.
When the reading seems wrong, resist the temptation to cast again. The second casting is almost always a way of rejecting the first answer rather than genuinely seeking more clarity. Sit with the reading that arrived. Write it down. Come back to it in a few days.
Sometimes what seemed irrelevant becomes precisely accurate as the situation develops. Sometimes the hexagram was answering a question underneath the question you asked — something you were carrying but hadn't consciously articulated. Sometimes the reading is simply opaque and remains so.
All of these outcomes are part of the practice. The I Ching is not a machine that produces correct answers on demand. It is a conversation that develops over time, between the text and the practitioner, and it requires the same patience and good faith that any genuine conversation requires.
The hexagram that confuses you most is often the one that eventually teaches you most. Sit with difficulty rather than discarding it.

Your First Reading — Begin Today 開始
Find three coins. Find a quiet moment. Write down a genuine question about something that actually matters to you right now — not a test, not a trivial matter, but something real.
Toss the coins six times. Build your hexagram. Find it in your translation. Read it slowly. Write down what you receive and what you make of it.
That is all. The first reading rarely reveals everything. Neither does the hundredth. The practice deepens through accumulation — through the slow building of a relationship with the text over months and years, reading by reading, question by question.
The I Ching is not a text you finish. It is a practice you begin.
Begin today.
