I Ching (Yi Jing, Book of Changes) is one of the oldest systematic philosophies of change in East Asia. This guide explains what it is, how to read hexagram texts, and how divination supports—not replaces—rational decision-making.
What is the I Ching?
The received text combines the hexagram core (names, judgments, line statements) with the Ten Wings commentaries. "Change" (易) implies both transformation and underlying pattern.
Core building blocks
| Layer | Content |
|---|---|

Five-step reading method
- Read the hexagram name for imagery.

- Consult commentary traditions (Ten Wings).
- Apply insights to your specific question.
Divination ethics
- One focused question per session.
