The I Ching: a guide to the Book of Changes

The I Ching, also known as the Zhouyi or Book of Changes, is a Chinese classic organized around 64 six-line figures. This guide introduces the basic structure and a simple coin-casting method, with room for curiosity rather than claims of certainty.

What is an I Ching hexagram?

Each hexagram is made of six lines, read from the bottom upward. A solid line is conventionally associated with yang; a broken line with yin. The lines combine into two three-line trigrams, creating a symbolic image that readers have interpreted in different ways across time and traditions.

The figures are not a modern personality test or a scientific forecast. Readers often approach them as a structured way to pause over a question, consider a changing situation, and reflect on possible conduct.

How does the three-coin method work?

1. Choose one focused question. Avoid including private details you would not want stored or shared.
2. Toss three coins for the first line. In the common counting convention, heads count as 3 and tails as 2.
3. Add the three values: 6 is changing yin, 7 is yang, 8 is yin, and 9 is changing yang.
4. Repeat five more times, adding each new line above the previous one. The completed pattern identifies a hexagram; changing lines may also point to a relating figure.

How to read a result thoughtfully

Start with the figure’s name and image, then consult a reliable translation or the classical text. Keep the historical text distinct from a modern interpretation. Ask what the image brings into focus, what assumptions it challenges, and what small, responsible action is available to you.

Different editions and schools explain the text in different ways. CastQigua offers introductory, contemporary reflection prompts inspired by the tradition; they are not scholarly translations, professional advice, or promises about the future.
