In brief
Key takeaways
- Use any three coins, assign values consistently, and record six totals.
- The first cast is the bottom line; the sixth cast is the top line.
- Values 6 and 9 are changing lines, creating a related resulting hexagram.
Preparation
Consulting the I Ching is a contemplative act. Before you begin, create a calm environment — find a quiet space, take a few deep breaths, and set aside distractions. Many practitioners light incense or sit in meditation briefly to center their mind.
You will need three coins of any kind. Traditional Chinese bronze coins work well, but any coins will do — assign one side as "heads" (value 3, yang) and the other as "tails" (value 2, yin).
The three-coin method is a widely used traditional simplification. The older yarrow-stalk method takes longer and gives the four line values different probabilities, so readings from the two methods are not statistically identical.
Approach the reading with sincerity and genuine curiosity rather than trying to test it. Treat the text as a structured prompt for reflection: its value comes from the attention you bring to the question and imagery.
Forming Your Question
The quality of the I Ching's guidance depends heavily on how you frame your question. A good question is:
- Open-ended: "What do I need to understand about this situation?" rather than "Should I do X or Y?"
- Sincere: Ask about something that genuinely matters to you.
- Present-focused: "What is the nature of my current relationship with my work?" is better than "Will I be rich in ten years?"
- Personal: Ask about your own situation, not about other people's business.
If a response confuses you, sit with it before repeating the question. Clarity often comes through reflection, not repeated casting.
The Three-Coin Method
Hold the three coins, concentrate on your question, and toss them together. One common convention assigns heads = 3 and tails = 2; some editions reverse the faces, so the important thing is to stay consistent for all six casts. Add the three values and record the total.
| Total | Line | State | Change |
|---|---|---|---|
| 6 | Old yin | Changing | Becomes yang |
| 7 | Young yang | Stable | Remains yang |
| 8 | Young yin | Stable | Remains yin |
| 9 | Old yang | Changing | Becomes yin |
Building the Hexagram
Repeat the coin toss six times to create your hexagram. Here is the crucial detail: build the hexagram from the bottom up. Your first toss forms the bottom line (line 1), and your sixth toss forms the top line (line 6).
Draw the results from bottom to top: line 1 ⚊, line 2 ⚋, line 3 ⚊, line 4 ⚋ changing, line 5 ⚊ changing, and line 6 ⚋. The primary figure is Hexagram 63, After Completion.
Change line 4 from yin to yang and line 5 from yang to yin. The related figure is Hexagram 55, Abundance. Read the primary figure, both changing-line texts, and the resulting figure as connected perspectives.
Changing Lines
Lines with values of 6 or 9 are changing lines — they represent points of active transformation in your situation. These lines are especially significant and carry their own specific line statements in the Zhouyi text.
When you have changing lines, create a resulting hexagram by transforming each changing line into its opposite (old yin becomes yang, old yang becomes yin). The primary hexagram frames the current situation; the resulting figure offers additional context or a possible direction of change, not a guaranteed future.
Interpreting Your Reading
There is no single universally accepted protocol, especially when several lines change. One common modern approach is to read the associated text in this order:
- The Judgment: The core message of the hexagram, traditionally attributed to King Wen.
- The Image: A later Ten Wings commentary describing the hexagram's natural imagery and the conduct it suggests.
- Changing Line Texts: If you have changing lines, read those specific line statements. They often provide the most targeted material for reflection.
- The Resulting Hexagram: Read the Judgment of the related figure as another perspective on how the situation may develop.
Interpretive schools differ on how to weigh several changing lines. Beginners can start by reading every changing-line text in order and noting themes that repeat across the primary and resulting figures. The hexagram structure guide explains the underlying line and trigram relationships.
Tips for Practice
- Keep a journal: Record your questions, hexagrams, and reflections. Over time, you'll develop a deeper understanding of how the I Ching speaks to you.
- Be patient: The I Ching's language is poetic and symbolic. Meaning often unfolds over hours or days, not minutes.
- Revisit your wording: If a reading seems unrelated, check whether your question was too broad, predictive, or focused on someone else's choices.
- Study the hexagrams: Familiarize yourself with the 64 hexagrams over time. The more context you know, the richer your readings can become.
- Use it deliberately: Avoid casting from boredom or repeatedly testing the same question. A slower practice makes room for reflection.

Common questions
Frequently asked questions
Do I need special Chinese coins?
No. Any three coins will work. What matters is assigning one side the value 3 and the other the value 2, then using that assignment consistently for all six casts.
Which line of a hexagram is drawn first?
Draw from the bottom up. The first cast creates line 1 at the bottom, and the sixth cast creates line 6 at the top.
What if there are no changing lines?
Read the primary hexagram’s Judgment and Image as the central guidance. With no 6 or 9 values, there is no separate resulting hexagram to compare.
What if several lines are changing?
Read the primary hexagram, the relevant changing-line texts, and the resulting hexagram together. Schools differ on how they prioritize multiple lines, so use one method consistently and avoid forcing a single literal prediction.
Can I repeat the same question?
It is usually more useful to reflect on the first reading before asking again. If the question was unclear, rewrite it to focus on what you need to understand or how you can respond.
