How do six lines become a hexagram?
From two kinds of line to eight trigrams and sixty-four ways of viewing a situation. Take a minute to understand the figure before deciding how far you want to explore.

The I Ching is about change—and the people living through it.
Circumstances keep shifting, yet people still face familiar questions: when to advance or step back, how to use power, and how to navigate trust and suspicion.
The sixty-four hexagrams give structure to these recurring situations. They do not decide for you; they help you see where you stand, what is taking shape, and what the next step may ask of you.
