How to read it
How to ask a question that can be answered, how to weigh a changing line, and how to read a hexagram in order.
Frequently asked
How do I cast an I Ching hexagram online?
Hold one question in mind, then toss three coins six times. Each toss produces a line. Lines are built from the bottom up — the first toss is the bottom line, the sixth is the top. Two heads and one tail gives a young yang line, two tails and one head a young yin line. Three heads is a changing yang line, three tails a changing yin line.
What is a changing line?
A changing line (moving line) is a line that flips into its opposite once the reading is complete. Young lines stay as they are; changing lines transform. The hexagram you cast is the primary hexagram, and the hexagram that results after the changes is the transformed hexagram.
Do I need real coins?
No. The traditional method uses three Chinese coins, but any three coins work — or you can tap the cast button and let the site generate the tosses with a cryptographic random source. The mathematics are identical.
Can I ask more than one question?
One hexagram per question. Casting repeatedly on the same question until you get an answer you like defeats the purpose — the classical texts are explicit about this. Ask once, sit with the answer, and come back to it later.
Is this the same as a tarot reading?
No. The I Ching is a Chinese classic built from 64 six-line figures, each with a judgment and six line texts. A reading is a fixed structure — primary hexagram, changing lines, transformed hexagram — rather than a spread of cards.
What does "six-line" mean?
Six-line (liuyao) is a Han dynasty method that attaches Heavenly Stems and Earthly Branches to each line, along with the Six Relatives and Six Spirits. It turns a hexagram into a working model of a situation: who is helping, what is blocking, where the resources sit.
What makes this different
Most online I Ching sites throw out a one-paragraph interpretation written on the fly, and it changes every time you reload. Here the hexagram, the changing lines, the transformed figure, the palace, the Six Relatives and the Six Spirits are all computed deterministically from your six tosses. The same tosses always give the same reading. The English text is a reading guide, not a fortune — it tells you what the hexagram says, and leaves the decision with you.
Before you cast
Narrow the question to one thing that can be answered — a direction, a yes or a no, a timing. The classical texts warn against asking the same question twice. Sit with the first answer. If it does not resolve, the second reading should be a different question.
