Casting the I Ching for someone else: who tosses, how to ask, how to tell them

Yes, you can cast the I Ching for someone else; reading for another person is as old as the book. The essentials are simple: the question should be theirs, in their words, about their situation; it matters less who physically tosses the coins than that the person is present in mind and agrees to the reading; and when you give the answer, you share the text and your reading of it, clearly separated, without turning it into a prediction.

An old practice

The Zhouyi began as a tool of specialists. The earliest stories of its use, in the Zuo Zhuan (左傳), are of court scribes (史) and diviners casting on behalf of rulers and nobles. In one well-known episode a scribe from the Zhou court visits the state of Chen, is asked by the ruler to divine about his young son, and obtains Guan, Contemplation changing into Pi, Standstill — the moving line being the fourth, "contemplating the light of the kingdom" (觀國之光). The scribe then explains the line to the ruler.

So the tradition has no objection to one person casting and another person asking. What it does care about is the seriousness of the question and the sincerity of the asker, which is where most of the practical choices come from.

Who should toss the coins?

Teachers differ here, and it is worth knowing the options rather than pretending there is one rule:

• The asker tosses. Many readers prefer this when the person is with you. Holding the question and throwing the coins themselves keeps them engaged, and it removes any suspicion that you steered the result.
• You toss on their behalf. This is the older pattern of the professional diviner, and it is common when the person is far away or uncomfortable with the ritual. Ask them to state the question, then cast while holding their words in mind.
• Both, in turn. Some readers have the asker shake the coins and the reader throw, or the reverse. This is a matter of taste.

Whichever you choose, decide before you begin, and do not cast again because someone dislikes the result. The Judgment of Meng puts it bluntly: 初筮告，再三瀆 — the first cast informs; asking again and again is importunate. That applies just as much when the asker is a friend; there is more on this in can you ask the same question twice.

If you practise Six Lines (六爻) divination, casting for someone else also changes the technical reading: which line stands for the person asking, and which for the matter, depends on who the asker is and what relation they have to the subject. See the use spirit and the self and response lines. Reading the text, as this site does, needs no such adjustment.

Helping them frame the question

Most of your value as a reader comes before the coins are thrown. People often arrive with a question shaped like a prediction ("Will he come back?") or a demand for a verdict ("Should I quit?"). Help them turn it into something the book can answer:

• Make it theirs. "What should I understand about my part in this relationship?" rather than "What is he thinking?" The I Ching speaks well about a situation and your conduct in it; it is a poor window into someone else's mind. Asking about another person covers this in detail.
• One matter at a time. If they have three worries, pick the one that matters most today.
• Open, not yes-or-no. "How should I approach the job offer?" leaves room for an image and a direction. How to ask the I Ching a question has before-and-after examples.
• Write it down, in their words, before anyone touches the coins.

Be careful about casting about someone who has not asked. A parent wanting to know about an adult child's choices, or a friend curious about a colleague, can still consult the book — but the honest question is about their own role: "How can I support my daughter's decision?" rather than "Will her marriage last?"

Presenting the answer responsibly

When the hexagram is cast, slow down. The person is likely to hang on your first words.

• Show them the text. Open the hexagram page together, read the Judgment and any moving lines aloud, and let them see the original alongside the translation. The texts belong to them as much as to you.
• Separate text from interpretation. Say "the line text says…" and then "the way I read it…". That keeps your opinion from sounding like the oracle's.
• Read the moving lines by a consistent rule. Use the standard conventions in the changing-lines guide rather than choosing whichever line sounds best.
• Describe, don't predict. The book describes a situation, its tendency and the conduct that suits it. "This looks like a time to hold back and gather strength" is a reading; "it will fail in March" is not.
• Handle difficult hexagrams gently. If they draw Kan, the Abysmal, point out that its Judgment speaks of sincerity and a heart that gets through: 習坎，有孚，維心亨. Hard hexagrams counsel; they do not condemn. See difficult hexagrams.
• Know the limits. A reading is not a substitute for a doctor, a lawyer or a financial professional. If the question is really about one of those, say so kindly and suggest they talk to the right person.

Finally, leave the decision with them. The best outcome of a reading for someone else is that they leave thinking more clearly about their own situation, not that they leave dependent on you.

Your own part as the reader

• Step back when you are involved. If the question touches you — your relationship with the person, or a matter where you have a stake — it is hard to read without bias. Suggest they cast and read for themselves, and help only with looking up the text.
• Keep it confidential. People bring questions they would not share with anyone else.
• Don't over-read. Where the text is silent, say so rather than filling the gap to sound wise.

A short checklist

• Agree that they want a reading, and on who will toss.
• Help them write one open question about their own situation.
• Cast once; record the six numbers, the hexagram and the moving lines.
• Read the text together, then give your interpretation, clearly labelled.
• Suggest they note the question and reading in a journal and revisit it later.

You can cast on the I Ching page with the person beside you, and they can keep the result to read again.
