If Fu Xi created the trigrams, it was King Wen who gave the I Ching its voice. Imprisoned by the tyrant Zhou Xin, the last ruler of the Shang Dynasty, King Wen spent seven years in a dungeon at Youli. Instead of despairing, he turned inward and transformed the trigrams into hexagrams, writing the judgment texts (guaci) that form the heart of the I Ching.
The Prisoner and the Book #
King Wen’s story is foundational to Chinese culture. A virtuous man unjustly imprisoned, he responded not with bitterness but with creation. Tradition holds that he took Fu Xi’s eight trigrams and paired them to form 64 hexagrams, arranging them in a sequence that describes the arc of all possible situations — from Heaven and Earth to Completion and the eternal Not-Yet-Completed.
For each hexagram, King Wen composed a brief judgment — sometimes a single line, sometimes a few sentences — that captures the essence of the situation and offers guidance. These judgments are the oldest layer of the I Ching’s text, and their lapidary style has inspired commentary for three thousand years.
The Voice of the Judgments #
The judgments are not oracles in the sense of predicting the future. They do not say “you will meet a tall dark stranger.” Instead, they describe a pattern — a configuration of forces — and offer counsel on how to navigate it.
Qian (Hexagram 1, Heaven) is described with four characters: yuan (sublime), heng (success), li (benefit), zhen (steadfastness). These became known as the Four Virtues, and later Confucian commentators built elaborate philosophical systems around them.
Kun (Hexagram 2, Earth) offers a different kind of wisdom: “Sublime success through the perseverance of a mare.” The mare — strong but not aggressive, capable but following rather than leading — embodies the yin principle of receptive power.
Some judgments read like poetry. Hexagram 62, Xiao Guo (Small Exceeding): “The bird in flight leaves its call behind. It should not ascend; it should descend. Then there will be great good fortune.” The image is hauntingly specific, yet its meaning is open to endless interpretation.
A Text in Layers #
King Wen’s judgments were later supplemented by line statements (yaoci), traditionally attributed to his son, the Duke of Zhou. These provide guidance for each of the six lines within a hexagram, adding detail and nuance. Later still, the Ten Wings — a set of commentaries attributed to Confucius and his school — added philosophical depth, transforming the I Ching from a divination manual into a work of wisdom literature.
The result is a text with many voices speaking across the centuries. King Wen’s voice — terse, authoritative, shaped by suffering — remains the foundation. To read his judgments is to hear a man in a dungeon, staring at patterns of broken and unbroken lines, finding in them the structure of the universe.
