Three broken lines, the only trigram with no yang in it. Kun is the capacity to carry, to yield and to sustain. It describes what a situation is resting on, and it does not begin anything.
The judgement belongs to the doubled hexagram, Hexagram 2, The Receptive. It opens with the same four words as Qian's and then qualifies one of them, which is the entire point.
Where Qian's firmness is unqualified, Kun's is the firmness of a mare. Legge's 1882 English keeps the animal, and it matters: a mare is strong, and it follows. The text then says plainly that taking the initiative here leads astray while following finds the way. It adds a direction, gaining companions in the southwest and losing them in the northeast, which is the earliest place in the book where geography is used as a category rather than as a place.
The Image for the doubled hexagram is the carrying power of the earth, and from it the noble person supports things with breadth of character.
The picture is load-bearing in the literal sense. Earth does not choose what it carries, does not push back, and does not stop being underneath things when that becomes inconvenient. The conduct drawn from it is capacity rather than action: being large enough that other people's weight does not deform you. The failure implied by the same image is equally plain. Ground that carries everything indiscriminately also carries what should have been refused, and nothing in the picture supplies a way of telling the two apart. That silence is the honest part of the image.
Kun is three broken lines, the only trigram with no yang in it at all. The Shuo Gua gives it earth, the mother, the ox, the belly, cloth, the direction southwest, and the quality shun, usually rendered as yielding or devotion, though compliance is closer to the Chinese. The ox is the useful attribute: an animal of enormous strength whose entire function is to be directed by somebody else.
As the lower trigram, Kun means the base of the situation is receptive. The querent is the ground, absorbing rather than driving, and whatever movement exists comes from above. As the upper trigram it means the outer conditions will not resist, which is comfortable and is not the same thing as help. An open field offers no obstruction and no direction either, and readers routinely mistake the first for the second.
What Kun does not describe is passivity, and the English word receptive has done real damage here. The trigram is capacity under load. Its failure is not weakness but indiscriminate carrying: the situation where somebody is strong enough that nobody thinks to ask whether they should be holding this at all. Which reading applies depends on the question. Asked what to do, Kun says follow. Asked what is happening, it frequently says you are the reason nothing has collapsed yet. Those are close to opposite instructions, and only the question separates them.
Support, accommodation, and the work of keeping a relationship habitable. Kun describes the person who adjusts, who makes room, and who gets described afterwards as easy to be with.
That is a real capacity and worth naming as one. The question the trigram raises and does not answer is whether the adjusting runs in both directions. Doubled, the figure has no initiating line anywhere in it, and a relationship with no initiating line tends to drift rather than break. Asked whether somebody is committed, Kun reads as yes. Asked whether they will ever say what they want, it is a good deal less encouraging, and that gap is the thing to look at.
Support work, execution, and the roles that hold an organisation up without appearing anywhere in the story it tells about itself. As the lower trigram, Kun says the querent is the foundation the work stands on. As the upper trigram it says the environment is permissive and will not push back, which suits a person with their own direction and strands one waiting to be given it.
The trigram favours following a clear lead over supplying one. That is not a small thing: most work is execution, and the book is unusually respectful of it. The risk it carries is invisibility, because the qualities that make this work valuable are the ones that make it hard to point at.
Reserves rather than income. Kun describes what is already there and what it can bear: savings, slack, the capacity to absorb a bad month without anything breaking.
It is not about a gain and it names no course of action. In a money question its useful contribution is usually the unglamorous one, that the base is either sounder or thinner than the querent believes, and that this is discoverable by looking rather than by divining. Its risk is the trigram's general risk, which is carrying obligations nobody ever agreed to, quietly, because there was enough room to absorb them. Room is not the same as consent.
Follow rather than lead here, and be specific about whom. Pick the person, the standard or the plan you are actually going to follow, name it out loud, and stop reserving the option to take over halfway. The advice of this trigram is not to do less. It is to stop splitting the difference between leading and following, which costs more than either one. If you cannot name what you are following, you are not following, you are waiting.
Kun is 000: three yin lines, no yang anywhere. Like Qian it is its own inverse, and its opposite line for line is Qian, the Heaven Trigram, 111.
Kun's effect on a partner trigram is to give it somewhere to happen. Below, it is the ground and the upper trigram is the event. Above, it is open space and the lower trigram is what rises into it. Either way Kun is the context rather than the subject, and the reading usually belongs to the other half of the figure.
The sharpest demonstration is what a single yang line does to it. Five yin lines with one yang at the top is Hexagram 23, Splitting Apart, where the last solid line is being stripped off. Turn that same figure over and the yang line sits at the bottom: Hexagram 24, Return, where the same single line is coming back. One line, two positions, and the whole distance between decay and recovery.
Doubled into Hexagram 2, Kun stops being the ground under something else and becomes the entire situation, which is why that hexagram has to spend its text telling the reader what to do with pure receptivity. The trigram alone never has to answer that.
Kun's oldest layer is the same as the rest of the book: a Zhou-era divination manual, roughly ninth to eighth century BCE, giving hexagram and line texts and explaining nothing. The trigram is assumed, never introduced.
The attributes come from the Ten Wings, and specifically from the Shuo Gua, compiled across the Warring States and Han periods. Earth, mother, ox, belly, cloth, the southwest: all of it is commentary written centuries after the oracle, systematising material that was never a system.
The English layer is where most of the trouble sits. Legge in 1882 and Wilhelm in 1924 both worked in a register that turned shun into wifely devotion, and Wilhelm's German was filtered again through Cary Baynes's 1950 English. The Chinese word is closer to compliant, or going along with, and it is applied to ministers, soldiers and terrain as readily as women. A great deal of what English-speaking readers believe the Yi says about the feminine is in fact what two European men thought in the decades around 1900.
One older tradition is worth raising because it unsettles an ordering everybody takes for granted. Han sources refer to two earlier divination systems, Lianshan and Guicang, the second of which is said to have begun with Kun rather than with Qian. Bamboo slips excavated at Wangjiatai in 1993 have been identified by many scholars as that type of manual. The evidence is fragmentary and the identification is still argued over, but it is enough to show that putting heaven first was a choice, not a fact about the figures.
The first misreading is passivity. Receptive, in English, suggests doing nothing, and readers take Kun as an instruction to wait. The trigram describes bearing weight, which is not inactivity and is frequently harder than acting. A situation resting on Kun is being held up by somebody, and a reading that misses that also misses who.
The second is gender. The Shuo Gua assigns Kun the mother, and a century of English commentary has treated that as licence to read the trigram as a woman in the querent's life, usually with advice attached. It is a Han-era filing system rather than a description of a person, and applying it to somebody specific produces confident claims about a person who has not been consulted.
The third is treating Kun as the weak half of a pair with Qian. The book does not rank them, and the doubled hexagram opens with the same formula as the doubled Qian. Reading Kun as the lesser trigram makes half the figures in the system look like problems, when what they describe is a situation that has a foundation. The doubled Kun is not a warning and the doubled Qian is not a prize; they are two different accounts of where the movement in a situation is coming from.
Put a real question to the coins.
