What Is the I Ching?

The Book of Changes (I Ching / Yijing, 易經) began as an oracle-bone divination manual more than three millennia ago and became one of the foundations of Chinese thought. Its system is elegant: eight trigrams (八卦) — Heaven, Earth, Thunder, Water, Mountain, Lake, Fire and Wind — stack in pairs to form 64 hexagrams, each a snapshot of a moment of change. People consult the I Ching on decisions, relationships and timing by casting coins or yarrow stalks and reading the resulting hexagram. Read the full history →

Frequently Asked Questions

What is the I Ching?

The I Ching (Yijing, 易經) or Book of Changes is a 3,000-year-old Chinese classic used for divination and reflection. It consists of 64 hexagrams — six-line figures built from eight trigrams — each naming an archetypal situation and how to act within it. Start with the beginner guide.

How do I read the I Ching for beginners?

Hold a sincere question, cast three coins six times to build a hexagram from the bottom line up, then read that hexagram's Judgment and Image and its interpretation for your situation. Our step-by-step guide walks through every step.

Which side of the I Ching coins is heads?

Traditionally the coin side with four characters counts as 3 points (heads) and the plainer side with two characters counts as 2 points (tails). Throw three coins and add: a total of 6, 7, 8 or 9 decides each line. See the coin method explained.

What are changing lines in the I Ching?

When a coin toss totals 6 (old yin) or 9 (old yang) that line is changing and flips into its opposite, pointing you to a second hexagram that shows where the situation is heading. Full explanation: changing lines.

Can I cast the I Ching online for free?

Yes — our three-coin casting runs entirely in your browser: no account, no tracking, instant result with both hexagrams when changing lines appear.
