Lines

The line is the atomic I Ching entity - that is, it is the only entity that cannot be broken down further. A single line represents duality, a yin or a yang, and can be in one of two states: stable or changing. That is, a line can take one of four different forms:

1. A yang, represented as: (a black line).
2. A yin, represented as: (a black divided line).
3. A changing yang, represented as: (a red line).
4. A changing ying, represented as: (a red divided line).
