Fire under earth: the light has gone below the horizon. Darkening of the Light describes a period when intelligence is dangerous to display, and its advice is to keep working and stop showing.
Thirty-sixth in the King Wen order. The Sequence places it after Progress, with an unusually grim piece of reasoning: whoever advances is certain to be wounded, and ming yi is the wounding of the light.
Legge's 1882 English is short: it will be advantageous to realise the difficulty of the position, and to maintain firm correctness.
Both halves matter. Realising the difficulty is not resignation, it is an instruction to assess accurately, because the characteristic error under this hexagram is behaving as though conditions are normal when they are not. Maintaining correctness is the part that costs. The judgement does not permit the obvious response, which would be to adapt to a corrupt situation by becoming part of it. It asks for accurate assessment and unchanged conduct at the same time, and those two together are expensive.
The Image is the earth with the bright sun beneath it, and from it the noble person manages people by keeping his intelligence obscured.
That sentence is the hexagram. The light has not gone out; it is underneath, which is a position rather than a loss. What the Image asks for is deliberate dimming: continuing to see clearly and declining to display it. This is one of the few places in the book that recommends concealment outright, and the recommendation is narrowly conditional. It applies where visibility is dangerous. It is not a general policy for getting along with people.
Darkening of the Light is fire under earth: the sun below the horizon. It describes a period in which clarity, competence or integrity is a liability rather than an asset, and in which the situation is governed by somebody or something that punishes those things.
The structure makes an unusually direct point. Five of the six lines are correctly placed, and the one that is not is the fifth, the ruler's seat. In its inverse, Hexagram 35, Progress, the arrangement is reversed and only one line is correct. Put the two together and you have a complete political argument: in one figure everything is out of place except the servant, and in the other everything is in place except the ruler.
What the hexagram does not say is that the situation is permanent, and it does not counsel resignation. The advice throughout is to keep going, keep working, and stop performing. Its opposite, line for line, is Hexagram 6, Conflict, where the disagreement is out in the open. Asked what is happening, this figure says the conditions are hostile to being right. Asked how long that lasts, it declines to answer, and the line between prudence and permanent hiding is not one it will draw for you.
A relationship in which honesty is currently costly. Something true cannot be said, or can only be said at a price the querent is not yet prepared to pay. Darkening of the Light is not the hexagram of deceit. It is the hexagram of clarity withheld under pressure.
That distinction matters and it is easy to lose. Concealment here is a response to conditions rather than a strategy for advantage, and the figure assumes the concealed thing stays intact. Where this turns up in a relationship reading, the useful question is what exactly cannot be said and what makes saying it dangerous, because the hexagram is far more interested in the conditions than in the secret.
Working under a bad manager, in a hostile culture, or in an organisation where competence attracts the wrong kind of attention. This hexagram covers the situation where doing good work and being seen doing it have come apart.
Its advice is specific and unusual: continue the work, reduce the display. Keep the standards, stop volunteering, let the visible surface be unremarkable. That is a real strategy with a real cost, which the text acknowledges in the first line, where the traveller goes three days without eating and is spoken of derisively. Nothing here says stay indefinitely. It describes how to survive a period, not how to build a career.
A financial position better kept quiet, or one under pressure from something the querent does not control. The hexagram describes conditions rather than amounts, and the conditions are adverse.
Its practical contribution is the instruction to assess accurately first. The judgement's opening move is to realise the difficulty, which in a money question means establishing what the actual position is before deciding anything, particularly where it has been comfortable not to look. Nothing here constitutes advice about a holding, a debt or a decision, and a hexagram about hostile conditions is a reason to gather information rather than to act.
Keep doing the work and stop showing it. Pick the one place where you have been demonstrating competence to people who are not rewarding it, and quietly stop demonstrating while continuing to do it. Then write down, privately, what conditions would have to change for you to be visible again. This hexagram describes a period, and a period with no end written down anywhere tends to become a permanent arrangement.
A bird flying with drooping wings. The traveller goes three days without eating and is spoken of derisively wherever he arrives. It is the bleakest opening line in this stretch of the book.
The line is correctly placed, yang in a yang position, and it has an answering line at the fourth, which makes the hardship harder to explain away as a fault of its own. This is what being right early costs. The text does not console it. Changing it produces Hexagram 15, Modesty, where the same lowered posture becomes a virtue rather than an injury.
Wounded in the left thigh, and saved by the strength of a swift horse. The verdict is fortunate, which sits oddly on a line about an injury.
The wound is real and so is the escape, and the structure supports both. This line is correct and central in the lower trigram, so it has standing, and the fifth line above it is also yin, so there is no support from the ruler. Well placed and unassisted is exactly the situation you get out of by your own speed. Changing it gives Hexagram 11, Peace.
Hunting in the south and capturing their great chief, followed immediately by a caution: do not be eager to put everything right at once.
This is the strongest line in the lower trigram, correctly placed at its top, answering the sixth. The victory is genuine and the warning concerns what comes after it. Removing the head of a bad situation does not repair the situation, and haste at that particular moment is the error the text names. Changing it produces Hexagram 24, Return, where a single strong line comes back at the bottom of the figure.
Entering the left side of the belly, getting hold of the mind of the master, and then leaving by the gate and courtyard. Legge's phrasing is obscure and the sense is not: somebody has been close enough to understand what they are dealing with, and has used the understanding to get out.
The line is correctly placed in the upper trigram, nearest the ruler's seat. This is departure from proximity, made with information rather than in panic, which is the only clean exit anywhere in the hexagram. Changing it produces Hexagram 55, Abundance.
The Count of Ji, and the advice to maintain firm correctness. It is one of the few lines in the book naming a historical person: Jizi, who by tradition survived the last Shang king by feigning madness.
It is also the only incorrectly placed line in the hexagram, a yin line in the ruler's yang seat, with no answering line at the second. The figure puts its named survivor in the one structurally wrong position, next to the darkness and unsupported. Concealment here is not a preference. Changing it gives Hexagram 63, After Completion.
Not advancing but going backwards. He first ascended to the top of the sky, and his future is to go into the earth. Traditionally this line is read as the tyrant himself rather than as anybody suffering under him.
The top line is correctly placed and answers the third, which is the line that captured the chief. The figure ends by describing the fall of the thing that made the darkness, and it does so without any satisfaction at all. Changing it produces Hexagram 22, Grace.
Darkening of the Light is 101000. Li, the Fire Trigram, is below and Kun, the Earth Trigram, is above: the sun beneath the ground.
The placement of the lines carries the meaning here more directly than in most figures. Five of the six are correctly placed. The single exception is the fifth, the ruler's seat, which holds a yin line in a yang position. A hexagram about intelligence being suppressed puts every line in order except the one in charge.
Turn the figure over and you have Hexagram 35, Progress, where the sun is above the earth and the arrangement inverts completely: one correct line instead of five. That split is arithmetically guaranteed rather than remarkable: turning a figure over moves every line between an odd position and an even one, so correctness flips for all six at once. What is not guaranteed is which line ends up the exception, and here it is the ruler. The pair states an entire political theory in six lines read from either end.
The nuclear figure, from lines two to five, is Hexagram 40, Deliverance, which is the most hopeful thing about this hexagram and the least visible. Underneath a situation of concealment and injury sits the figure of a tension being released. The surface says endure. The nuclear says this ends.
This is one of the few hexagrams with an explicit historical anchor. The fifth line names the Count of Ji, Jizi, an official under Zhou Xin, the last king of the Shang, who by tradition avoided execution by feigning madness. The sixth line has been read since at least the Han as describing the king himself: risen to the top of the sky and destined for the earth.
How much of that is Zhou-era and how much is later reading-back is genuinely uncertain. The Zhou conquest of Shang is the political event closest to the formation of this material, and a text produced by the winning side describing the losing king's fall is not a neutral document. Scholars still differ on how much of the Yi encodes that history and how much was found in it afterwards.
The rest is the usual sequence. Terse line texts first, the Ten Wings adding the Image and the trigram reading centuries later, and Legge in 1882 supplying the English most later versions worked from. His title, The Intelligence Wounded, is closer to the Chinese than the more atmospheric Darkening of the Light that replaced it.
The first misreading is despair. The figure is dark, the name is dark, and querents hear that nothing can be done. The hexagram's actual instruction is to keep working and stop displaying, which is an active strategy with a cost attached rather than a surrender. The light in the image has not gone out. It is underneath.
The second is treating concealment as a general policy. The text recommends hiding intelligence under conditions where showing it is dangerous, and it is describing a tyranny. Applied to an ordinary difficult workplace or an awkward relationship, the same advice becomes a licence for permanent evasiveness, which is not what any of the six lines is about.
The third is missing who the fifth line is. Because it names a survivor rather than a ruler, readers assume the ruler is elsewhere or absent. The fifth is the ruler's seat, and it is the only incorrectly placed line in the figure. The hexagram is not saying the darkness is atmospheric. It is saying, structurally, exactly where the darkness comes from, and that is the least comfortable and most useful thing in the figure.
Put a real question to the coins.
