The symbols of the I Ching, primarily made of lines, are simple, elegant, and ubiquitous, something that we can see all around us.
Lines
The I Ching is represented by combination of 2 symbols, primarily lines, or yao: a broken line and a straight line. Respectively, they symbolize the Yin (shadow) and the Yang (light), both of which at work in the cycle of changes.
Trigrams
When the lines are combined into threes patterns, each create a trigram. There are 8 trigrams, known as ba gua. This is the Feng Shui object you often see hanging on top of a door; or the ones you’ve seen on South Korean flag. Each trigram represents the natural world (left image, from top, clockwise): Heaven, Wood, Water, Mountain, Earth, Thunder, Fire, and Lake.
When these trigrams are combined, they create 64 Hexagrams, or six-line symbols. Each hexagram represents a particular state of natural change. These hexagrams provide valuable insights to anyone who seeks to read it.

A hexagram is a structure of 6 lines, with varying combinations of brokens and straights. For Carl Jung, each hexagram is an archetype, showing deep, universal insights of natural, human, and cosmic changes. Each is explained by a set of texts and commentaries. To know which hexagram you need, you have to ask a question, and do a random casting of coins.
