Contrasting hexagrams

 

  When all lines change, a hexagram turns into its contrast, or complementary hexagram.
  All yin lines are now yang, all yang lines are yin. Both are what the other is not.

Hex.3 at left is Thunder below Water
Hex.50 at right is Wind below Fire.

trigram Water
Trigram Thunder
trigram Fire
Trigram Wind

They are total opposites, hex.3 is the first beginning of things, hex.50 is the final result, the state with its laws and structure. Trigram Water is formless, trigram Fire is form and order. But every start is made for a completion and every completion was once started.
