The heart of the I Ching consists of two polar forces, represented by an unbroken line - yang - and an interrupted line - yin.
These can be combined into four different pairs:
old yin, smaller yang, smaller yin, old yang
cold, cool, lukewarm, warm
winter, spring, autumn, summer
…
Yin and yang form eight trigrams:
Heaven, Lake, Fire, Thunder, Wind, Water, Mountain, Earth
Putting two trigrams together each time creates 64 hexagrams. These correspond to the chapters of the Book of Change.
A chapter forms a pair with the following chapter - therefore resulting in 32 pairs. The two paired hexagrams are each other's opposite. The line pattern of one is reversed in its entirety to form the hexagram it is paired with. Also, their meanings are opposite and complementary.
There are eight hexagrams constructed symmetrically. If you reverse their line pattern, the result is identical. This is the case with: 1. Creation 2. Response
27. Jaws 28. Large Imbalance 29. Dark 30 Light 61. Inner Nobility 62 Small Imbalance. They form four pairs in which their six lines are mirrored: yin lines become yang, yang lines become yin. The illustrations of these four pairs in the text below have a yellow background colour.
The illustrations of the 28 pairs where the hexagrams are each other's reversals have a blue background colour.
