I Ching: Digital Mutations

The I Ching (ee-JING), also known as the Book of Changes, is the world's oldest divination system, originating in China over 3,000 years ago. It consists of 64 hexagrams — six-line figures made of solid (yang) and broken (yin) lines — that map the patterns of change within reality. It is both a philosophical text and an oracle.

The most common modern method is the three-coin method: toss three coins six times, building a hexagram from bottom to top. Each toss produces a yin or yang line, and some tosses produce 'changing lines' that transform the hexagram into a second figure. The traditional method uses 50 yarrow stalks for a more meditative process.

Changing lines (also called moving or mutating lines) are lines within a hexagram that are in the process of transforming from yin to yang or vice versa. When a hexagram contains changing lines, it produces a second hexagram showing how your situation is evolving. Reading both hexagrams together reveals the full arc of change.

A trigram (TRY-gram) is a three-line figure that is the building block of hexagrams. There are eight trigrams — Heaven, Earth, Thunder, Water, Mountain, Wind, Fire, and Lake — each representing a fundamental force of nature. Every hexagram is composed of two trigrams: an upper trigram and a lower trigram, whose interaction defines the hexagram's meaning.

The King Wen sequence is the traditional ordering of the 64 hexagrams, attributed to King Wen of Zhou (circa 1050 BCE). It arranges hexagrams in complementary pairs and is the standard numbering used in most I Ching texts. Chaos Tarot uses the King Wen numbering for all 64 hexagrams.
