Duration — 恒

What Is Hexagram 32?

Hexagram 32, Héng (恆), Duration, is Thunder over Wind — ䷟ — the hexagram of things that last: the pair that follows Influence in the sequence, the husband and wife of the 序卦, whose judgment offers passage and no blame on a single condition, whose Image asks a person to take a stand and not change it, and whose six lines run from a demand for depth at the very start to an agitation that never settles. The 彖 gives the name its gloss in three characters: 恆，久也 — 恆 means 久, lasting.

The character is written 恆 in the older tradition and 恒 in the modern one, and in either form it is the heart radical with strokes beside it. The contrast with the previous hexagram is hard to miss once it is seen. Influence is written 咸, without the heart; Duration carries it. The pair that the 序卦 calls husband and wife turns on that difference: one figure is named for being stirred, the other for what lasts once the stirring is over.

The sequence arrives at this hexagram through a chain rather than a list of consequences, and the link the 恆 clause picks up is a pair of ordinary people: 有天地然後有萬物，有萬物然後有男女，有男女然後有夫婦，有夫婦然後有父子，有父子然後有君臣，有君臣然後有上下，有上下然後禮儀有所錯. Only then comes the consequence: 夫婦之道，不可以不久也，故受之以恆；恆者久也 — the way of husband and wife cannot be brief, and so Duration follows; 恆 means lasting. The very next clause takes it back: 物不可以久居其所，故受之以遯 — nothing can remain long in its place, and so Retreat follows. The book gives duration exactly one hexagram and then, one sentence later, gives it a limit. The 雜卦 reaches for the same judgement in six characters, 咸速也，恆久也, influence is quick and duration is lasting, and the 疏 reads the pair as a contrast of structure: 咸明感應，故柔上而剛下，取二氣相交也。恆明長久，故剛上而柔下，取尊卑得序也 — attraction is read through two energies crossing, duration through two ranks taking their places.

The verdicts in this figure are uneven. Among the six lines 吉 appears once, 凶 three times, 吝 once, and 悔 only in the negated form 悔亡, regret gone. The character 咎, blame, does not appear in a line at all; it occurs once, in the judgment, negated. And the name is inside four of the six lines — 浚恆 in the first, 不恆其德 in the third, 恆其德 in the fifth, 振恆 in the sixth. Three of those four lines are graded negatively and the fourth is split. This is a hexagram that keeps saying its own name while its lines struggle to keep it.

Before anything else, the 疏 makes one point about the judgment that governs everything after it, and The Judgment below takes it up: what the way of duration values is adaptability, and only what keeps moving with circumstance can last. Every statement the figure later makes about standing and not changing has that sentence beside it.

Trigram Structure

Wind below, Thunder above — 巽下震上 — ䷟. The 彖 accounts for the name with four readings in one line: 剛上而柔下，雷風相與，巽而動，剛柔皆應，恆. The firm above and the yielding below; thunder and wind in each other's company; compliant and moving; firm and yielding, every one of them answered. The 疏 counts them as four separate grounds and works through them one at a time: 曆就四義釋恒名, four meanings are taken up to explain the name.

The first, 剛上而柔下, the firm above and the yielding below, is where 王弼 puts the hexagram's order: 剛尊柔卑，得其序也, the firm is honored and the yielding is low, and so they get their sequence. The 疏 frames this deliberately against the previous page, where the same six-stroke figure is read with the yielding line above and the firm below.

The second is 雷風相與, thunder and wind together. 王弼 reads the two as 長陽長陰，能相成也, the eldest yang and the eldest yin, each able to complete the other, and the 說卦 supplies the family: 震一索而得男，故謂之長男；巽一索而得女，故謂之長女 — thunder is the eldest son, wind the eldest daughter. The 疏 quotes 褚氏 on how the two work on each other: 雷資風而益遠，風假雷而增威, thunder borrows the wind and reaches farther, the wind borrows thunder and gains force. Two things that make each other stronger: that is the figure's picture of a long arrangement, and the two are not alike.

The third, 巽而動, compliant and moving, gets four characters from 王弼: 動無違也, movement with nothing crossing it. The fourth, 剛柔皆應, every firm and yielding line answered, gets 不孤媲也, nothing unpaired. The 疏 spells out the structure: 此卦六爻剛柔皆相應和，無孤媲者，故可長久也 — all six lines are paired, each with its counterpart, and nothing in the figure stands alone. Concretely, the first line answers the fourth, the second the fifth, the third the top, and each pair is one yielding stroke and one firm. Among the sixty-four this is not universal; plenty of figures contain lines with no partner at all. The classic's reading of Duration begins with the observation that no part of this shape is left on its own.

The 說卦's shorter lists add two details. Chapter seven gives the pair its verbs: 震，動也。巽，入也 — thunder moves, wind enters. Chapter eleven, which catalogs what each trigram contains, gives 震為雷、為龍、為玄黃、為敷、為大涂、為長子、為決躁 for thunder, and then for wind: 巽為木、為風、為長女、為繩直、為工、為白、為長、為高、為進退、為不果、為臭. Two entries in the wind's own list are worth pausing on. 為長、為高 — long, high: the trigram of duration is also the trigram of length, and of the plumb line (為繩直) and the craftsman (為工). And 為進退、為不果 — backing and filling, no settled outcome. The same trigram carries the book's plainest words for failing to hold a line, which is the subject of three of this hexagram's own lines.

Two structural relations close the picture. Turn the figure over and the lines read 咸, Influence, hexagram 31: the page before this one, the same shape seen from its other end. Reverse each line instead, firm for yielding, and the reading comes out 震下巽上, thunder below and wind above, which is hexagram 42, Increase. So the figure Duration inverts into the page before it, and negates into hexagram 42, Increase.

The Judgment

恆：亨，无咎。利貞，利有攸往。

Héng: hēng, wú jiù. Lì zhēn, lì yǒu yōu wǎng.

Our rendering: Duration: there is passage, and no blame. What serves is to hold to what is correct, and it serves to have a destination.

Read character by character:

The commentary opens with a question of counting. 王弼 writes 恒而亨，以濟三事也, duration and passage carry three things through, and does not say which three, so the 疏 spends a paragraph on the disagreement: 褚氏 reads them as 無咎, 利貞 and 利有攸往; 莊氏 reads 無咎 as one thing, 利 as a second and 貞 as a third; 周氏 reads 亨, 無咎 and 利貞. 孔穎達 settles it by reading the commentary against the text and rules for 褚氏: 觀文驗《注》，褚氏為長. It is a small moment and a revealing one, since the tradition that this page follows spends its energy on the plain question of what the sentence is doing rather than on anything hidden behind it.

The substance of the judgment comes next, and it is about flexibility: 恒久之道，所貴變通。必須變通隨時，方可長久。能久能通，乃「無咎」也 — what the way of duration values is adaptability; only by moving with circumstance can anything last; to last and to keep moving is what the judgment means by no blame. The 彖 then grounds the first three clauses in one cause, 久于其道也: they hold because the course is kept a long time, and 王弼 adds that nothing further is being promised, 道德所久，則常通無咎而利正也. The last clause gets an answer of its own.

From there the 彖 widens the frame. 天地之道，恆久而不已也 — the course of heaven and earth lasts and does not run out. 利有攸往，終則有始也 — going on has value because an end carries a beginning, and 王弼 completes the thought: 得其常道，故終則復始，往無窮極, having the constant course, the end returns to the beginning and the going has no limit. The examples that follow are drawn from things that are not people: 日月得天，而能久照，四時變化，而能久成，聖人久于其道，而天下化成 — the sun and moon keep to heaven and shine on; the four seasons change and still complete their work; the sage keeps his course and the world takes shape under it. Then the closing formula, which is the sentence to carry out of this hexagram: 觀其所恆，而天地萬物之情可見矣 — watch what a thing holds to, and the real condition of heaven, earth, and the ten thousand things becomes visible. The twin of that sentence is one page back, where the 彖 of Influence closes on 觀其所感, watch what a thing is stirred by. The two are read by the same formula with one word changed, and the two words are the whole difference between them.

Jungian reading: the figure's argument is that a lasting thing has not stopped moving; it keeps being chosen, and its characteristic failure is habit substituted for attention. Jung's psychology runs into the same problem from another direction: an attitude held without being revisited hardens into one-sidedness, and whatever has been kept out of that attitude comes back around it. Several of these lines describe the process from the inside — a person keeping a course after the reasons have gone quiet, holding a place with nothing left to hold, calling agitation a direction. The 疏's sentence about adaptability is that observation in the vocabulary of the classic, and the fifth line turns it into a question about function by asking who is supposed to be doing the deciding.

The Image

雷風，恆；君子以立不易方。

Léi fēng, héng; jūn zǐ yǐ lì bù yì fāng.

Thunder and wind: Duration. The noble one therefore takes his stand, and does not change his course.

The 大象 is built from the doubled trigram, and here it names the pair in the order 雷風, thunder first, wind second. 王弼 gives the instruction a single cause: 得其所久，故「不易」也, because he has found what lasts, he does not change it. The 疏 then fixes the word that carries the weight: 方猶道也, in this sentence 方 means the course, and that is what the instruction is about: 君子立身得其恒久之道，故不改易其方, the noble one establishes himself in the lasting course, and for that reason does not change it.

Set beside the previous page's Image, the two read almost as a dialogue. Influence ends with 君子以虛受人, the noble one receives others by keeping himself hollow; the work there is opening. Duration says 君子以立, the noble one takes a stand; the work here is not being moved off it. A person who only does the first has nothing to offer, and a person who only does the second cannot be reached. The book assigns them a hexagram each instead of asking for an average of the two.

One detail is easy to skip. The instruction is not advice about standing still; it assumes that offers will arrive, and that a course can be given up for something faster. A manner may be revised. The course is the part a person is standing on.

The Lines

初六：浚恆，貞凶，无攸利。 (Jùn héng, zhēn xiōng, wú yōu lì.) Dredging for lasting depth at the very start: holding to this brings misfortune, and nothing serves.

浚 is to dredge, to deepen, and the 疏 keeps the image literal: 浚，深也。最處卦底，故曰「深」也. 王弼 puts the whole failure in one motion: 處恒之初，最處卦底，始求深者也。求深窮底，令物無餘縕，漸以至此，物猶不堪，而況始求深者乎 — to ask for the bottom at the beginning leaves nothing over; even a depth reached by degrees wears things out on the way down, so what is to be said of someone who begins by demanding it. The 疏 adds a distinction that keeps the line from being an argument against depth itself: 施之於仁義，即不厭深；施之於正，即求物之情過深，是凶正害德 — with kindness, depth is never too much; with correctness, a person can ask for more of another's feeling than there is, and that is what damages both the demand and the one making it. The small image names the error exactly: 浚恆之凶，始求深也. Notice where this verdict sits. The harshest line in the figure belongs to the position that has not moved yet. Nothing has been done, nothing has been said, and there is only a demand.

九二：悔亡。 (Huǐ wáng.) Regret is gone.

Two characters, and no verdict beyond them. 王弼: 雖失其位，恒位於中，可以消悔也 — the line is firm in a yielding place, which is a fault in itself, but it stays in the middle, and that is enough to clear the debt; the 疏 agrees, 失位故稱「悔」，居中故「悔亡」也. The small image gives the method a verb: 能久中也, it can last in the middle. This is the quietest line in the hexagram and the one that answers the question the judgment raises about what actually makes something last. The answer offered here is a position rather than an intensity: no effort is praised, no good fortune is handed out, and the line's entire content is a subtraction. Compare the fourth line, which is also out of place: there the position is neither right nor central, and constancy in it earns nothing at all.

九三：不恆其德，或承之羞，貞吝。 (Bù héng qí dé, huò chéng zhī xiū, zhēn lìn.) Not lasting in his virtue: shame comes to him from somewhere; holding to this brings regret.

王弼's note on this line is a study in placement: 處三陽之中，居下體之上，處上體之下，上不至尊，下不至卑，中不在體，體在乎恒，而分無所定，無恒者也 — among the three firm lines but in no trigram's middle, above the lower figure and below the upper; not high enough to be honored, not low enough to be base, with no share fixed for it to hold: this is the person with nothing constant to be constant in. The word 德, virtue or character, is treated here as something a position can hold or fail to hold, which is why the failure is described as a gap in the structure rather than a moral lapse. 德行無恒，自相違錯，不可致詰, and since the character has nothing to keep, 或承之羞: shame arrives from more than one direction, 所羞非一. Then 施德於斯，物莫之納，鄙賤甚矣，故曰「貞吝」 — there is no one to take what is offered, and so the outcome is the book's mildest negative grade rather than a disaster. The small image finishes harder than the line does: 不恆其德，无所容也, there is nowhere for such a person to be received. The 疏 likens the case to the line in the Analects where reproach runs out, 於予與何誅 — there is nothing left to blame, because the person has no fixed place from which to answer.

九四：田无禽。 (Tián wú qín.) A hunt in the field, and nothing caught.

Three characters, and the line is a scene rather than an instruction. The 疏: 田者，田獵也，以譬有事也。「無禽」者，田獵不獲，以喻有事無功也 — the hunt stands for the work a person does, and the empty bag stands for work that comes to nothing. 王弼 gives the cause as briefly: 恒於非位，雖勞無獲也, constant in a position that is not his, labor without gain. The small image turns it into a question: 久非其位，安得禽也. Of everything in this hexagram this is the line with the most immediate use, because what it describes is not inconstancy. Nobody here gives up and nobody changes their mind; the persistence is real and only the field is wrong. Read alongside 九二's 能久中, the two lines carry the figure's argument about placement: lasting is not a virtue with its own value wherever it goes. It borrows its worth from where it is spent.

六五：恆其德，貞，婦人吉，夫子凶。 (Héng qí dé, zhēn, fù rén jí, fū zǐ xiōng.) Lasting in his virtue, held to it: good fortune for the wife, misfortune for the husband.

The verdict splits because the position is a governing one. 王弼: 居得尊位，為恒之主，不能「制義」，而系應在二，用心專貞，從唱而已 — the line holds the honored seat and is the master of this hexagram, but it cannot 制義, decide what is right; tied to the second line, it keeps one loyalty and follows the lead. From that, 婦人之吉，夫子之凶也. The small image sets the two functions side by side: 婦人貞吉，從一而終也。夫子制義，從婦凶也 — following one thing to the end is the wife's good fortune; deciding what is right is the husband's work, and following instead is his misfortune. The 疏 supplies the geometry: 五居尊位，在震為夫，二處下體，在巽為婦 — the fifth line stands in Thunder, the husband's trigram, the second in Wind, the wife's; and 五系於二，故曰「從婦凶」, a ruler taking his lead from below is what the line means by following the wife.

The household frame belongs to the text's own world, and the load-bearing word inside it is 制義, to cut out what is right, to decide. That is a function and not a sex, and the warning lands on any seat whose work is judgment and which has quietly handed the judgment to someone else: a manager, a parent, a partner who has stopped deciding and calls it loyalty or keeping the peace. This is also the figure's only 吉, granted to following. In a hexagram where misfortune appears three times, the one smooth verdict goes to the position that is permitted to keep its promise and is not required to make the call.

上六：振恆，凶。 (Zhèn héng, xiōng.) Agitation held as a standing course: misfortune.

振 is movement, shaking. The 疏: 振，動也。凡處於上者，當守靜以制動 — whoever stands at the top should keep stillness as the way of governing movement. 王弼 states the principle before the diagnosis: 夫靜為躁君，安為動主。故安者上之所處也，靜者可久之道也 — stillness is the lord of agitation and rest is the master of motion; the top is the seat of rest, and stillness is the way that lasts. Then the diagnosis: 處卦之上，居動之極，以此為恒，無施而得也 — at the top of the figure, at the extreme of movement, taking shaking as one's constancy, so that nothing done achieves anything. The small image closes the account: 振恆在上，大无功也.

Read with the first line, the two ends of this figure make one argument in opposite directions. The first line fails by demanding depth before anything has started; the last fails by keeping everything in motion and calling the motion a course. Between them the judgment has already named what neither possesses, 亨 and 无咎, passage with no blame, which the 疏 ties to adapting as circumstances move. The hexagram is not asking for stillness or for motion. It is asking where a person is standing, which is the question 初六 never asks and 上六 never answers.

How This Hexagram Shows Up in Daily Life

The subject of this hexagram is the persistence itself, and its first instruction runs against the usual way the word is used. The 疏 states it flatly: 恒久之道，所貴變通, what the way of lasting prizes is adaptability, and only what keeps moving with circumstance can keep going. What stays constant in this figure is a course, not a method. That distinction accounts for most of the practical content here, and it is the reason the Image can tell a person to stand without telling them to freeze: the method is the part that keeps being revised; the course (方) is the part that does not change.

The four failure modes the lines name are easier to recognize than the success. Demanding depth in the first month (浚恆) is what happens to a new project or a new relationship asked to prove everything before it has done anything, and the 疏's distinction is useful there: asking a great deal of someone's kindness is rarely the problem, while asking more of their feeling than they have is. Holding a position with nothing left to hold (九三) is the person whose role was never defined and who keeps changing shape to fit whatever is asked. Persisting in the wrong field (九四): the work, the arrangement, the habit that was right when it was chosen and is now being continued because stopping would mean admitting it changed. And 振恆, agitation accepted as a direction, is a recognizable modern condition — motion that produces nothing and is defended as momentum.

The 繫辭 files this hexagram in a list of nine, each with a virtue attached: 恒，德之固也, duration is the fixing of character; 恒，雜而不厭, duration is continuing among mixed and messy things without growing tired of them; 恒，以一德, duration is making a character one thing. Those three phrases describe the second line rather than the first or the last. The same book uses the character once more, in a warning attached to the top line of hexagram 益: 莫益之，或擊之，立心勿恒，凶 — when nothing is coming to you and something has begun to strike at you, a heart that cannot hold to anything is the misfortune. The test the figure leaves behind is short enough to run on any long commitment. Is this still what I chose, and is there any game in this field? The pairing with Influence supplies the rest. One of these figures asks a person to empty himself in order to receive; the other asks for a stand he will not give up, and the book does not pretend they are the same hexagram.

Frequently Asked Questions

What does Hexagram 32 mean in one sentence?

That what lasts is a course rather than a method: the 彖 glosses the name as 久, lasting, the 疏 reads the whole judgment through 恒久之道，所貴變通 — the way of lasting values adaptability — and the Image asks only that a person take a stand and not change his course, 君子以立不易方.

Why is 恆 rendered as Duration, and what does the 疏 mean by saying the way of lasting prizes adaptability?

恆 is the 彖's own gloss for itself, 恆，久也, and Duration is the plain English word for lasting. The figure's subject is not endurance under pressure but the persistence of a course, which is why the 疏's sentence 恒久之道，所貴變通 has to be read together with the Image's 不易方: what adapts is the manner, what does not change is the course. The 疏 fixes that reading by explaining 方 as 道, 方猶道也 — a method is what a course uses to keep going, and it is allowed to keep changing.

Why does the fourth line say a hunt in the field catches nothing, and what has that to do with constancy?

Because the line is 恒於非位, constant in a position that is not its own: 王弼 reads the empty bag as 雖勞無獲, labor without gain, and the small image asks the question outright, 久非其位，安得禽也. The line exists to say that persistence is not self-validating. The second line carries the same fault of position, a firm line in a yielding place, but it stands in the middle and gets 悔亡, regret gone; the fourth stands neither in place nor in the center and gets nothing.

Why does the fifth line say good fortune for the wife and misfortune for the husband?

Because of what the seat is for. The line holds the honored place and is master of the hexagram, but 王弼 says it cannot 制義, decide what is right; tied to the second line, 從唱而已, it only follows the lead. The small image gives the division of functions, 婦人貞吉，從一而終也；夫子制義，從婦凶也 — keeping faith to the end is the wife's good fortune, and deciding what is right is the husband's work, which is why following instead is his misfortune. The household language is the text's own frame; the load-bearing word is 制義, deciding, and the warning lands on any seat that has handed its judgment to someone else.
