Wu Wang is the hexagram of spontaneity. Thunder, the sudden movement, stirs beneath heaven, and the old readers saw the force of nature acting without scheme or second thought — the image of innocence in its oldest sense, the state of being free from ulterior motive. The judgment gives supreme success and perseverance. The teaching is that the unplanned, uncontrived act, done simply because it is right, carries a power that calculated action never does. The name means literally “without falsehood,” and the whole figure is an argument for the straight line.
Read against the working life, the figure is about the integrity of plain dealing. The second line is the book's finest statement of it: one does not count on the harvest while plowing, nor on the use of the ground while clearing it. The commentators saw here the whole ethic of work — do the thing itself, honestly, without scheming over the reward. The farmer who plants for the harvest alone, the text implies, has already poisoned the work with calculation.
For the bonds between people, Wu Wang was read as the trust that needs no defense. The third line, undeserved misfortune — the cow that was tethered is the wanderer's gain and the citizen's loss — was the ancients' hard acknowledgment that the innocent sometimes suffer through no fault of their own. But the fifth line is the balm: use no medicine in an illness incurred through no fault of your own. What comes by accident, they taught, departs by accident; the innocent person meets it without panic and lets it pass.
Within a cycle, this figure marks a phase when the simplest course is also the strongest. The image of thunder beneath heaven is the book's picture of natural force moving in its own rhythm, neither forced nor foreseen. The counsel is to act from the plain motive, to let the work be its own reason, and to meet the accidents of life without scheming — for the person who does not contrive has nothing that contrivance can undo.
