The Coin Method
The coin method is the most accessible and widely practiced I Ching casting technique today. It uses three coins, typically Chinese cash coins with a square hole, though any three identical coins work. Toss the coins six times, recording each result to build a hexagram from the bottom line upward.
Each toss produces one of three outcomes: three heads (yang, value 3), two heads one tail (yin, value 2), one head two tails (old yin, value 2 but changing), or three tails (old yang, value 3 but changing). The changing lines transform the hexagram into a second, future-oriented hexagram.
The Yarrow Stalk Method
The yarrow stalk method is the most ancient and ceremonially rich approach. It requires 50 yarrow stalks and a lengthy procedure of grouping, counting, and discarding stalks across 18 operations per line. The method takes 15-30 minutes per hexagram but carries a deep ritual significance.
The yarrow method was the standard in ancient China and remains the preferred method for serious practitioners and ceremonial divination. Its slow, deliberate pace is itself a form of meditation.
Plum Blossom Numerology Method
Plum blossom numerology, popularized by the school of Shao Yong, uses numbers rather than physical objects. The practitioner selects a set of numbers, often derived from the current time, a randomly chosen number, or a word's stroke count, and converts them into a hexagram.
Comparing the Three Methods
The coin method is fastest and most accessible. The yarrow method is most traditional and ceremonially powerful. The plum blossom method is the most flexible and can be performed mentally without any physical tools. All three produce identical hexagram structures.
Crafting Effective I Ching Questions
The I Ching responds best to questions framed as open inquiries about the present situation rather than yes/no questions or requests to predict the future. Good questions begin with How, What, or Why and focus on the querent's attitude and approach.

Frequently Asked Questions
Which I Ching method is most accurate?
All three methods produce the same hexagrams. Accuracy depends on the question quality and the reader's skill, not the method.
Can I use regular coins instead of Chinese cash coins?
Yes. Any three identical coins work. Traditional Chinese coins are preferred for their historical resonance but are not required.
How many hexagrams does the I Ching have?
The I Ching has 64 primary hexagrams, but with changing lines, each casting can produce up to 64 secondary hexagrams as well.
