I Ching – the Book of Changes and the 64 hexagrams
Published on October 22, 2026
The I Ching, the “Book of Changes”, is one of the oldest texts in the world. In 64 signs, the hexagrams, it describes typical life situations and how to meet them wisely. It is used as an oracle: you ask a question, toss coins and read the resulting sign.
From lines to hexagrams
The basis is solid (yang) and broken (yin) lines. Three lines form a trigram – there are eight, such as heaven, earth, water and fire. Two trigrams stacked form a hexagram of six lines; 8 × 8 = 64 possibilities.
Moving lines
When tossing three coins a line can “flip”. These moving lines show where the situation is changing and lead to a second hexagram: where the situation is heading. Lower lines concern rather the beginning of a matter, upper ones its end.
Asking well
The I Ching does not answer yes or no but describes the situation and a wise attitude. Good questions are open and concrete: “What should I consider in this job change?” rather than “Will I get the job?”. Ask a question once and let the answer sink in.
Frequently asked questions
How do I toss the coins?+
Toss three coins six times; heads count 3, tails 2. Each sum gives one line from bottom to top. The online oracle does this for you.
What is a nuclear hexagram?+
A hexagram formed from the middle four lines. It shows what runs beneath the surface.
Is the I Ching related to feng shui?+
Yes. The eight trigrams are the basis of the directions in feng shui and of the rings on the Luo Pan.
