Repeated Danger — 坎

What Is Hexagram 29?

Hexagram 29, Kǎn (坎), Repeated Danger, is Water over Water — ䷜ — danger heaped on danger, with the two firm lines of the figure standing at the middle of each trigram and all four yielding lines left at the ends. Its judgment promises no safety and no favorable outcome. It promises that something held inside can still pass through.

The name is a pit: 坎 is a trap, a sunken place, and it is also the name of the trigram Water. English versions have settled on calling the figure the abyss, or simply Water; the Chinese names the hole itself, and then names it twice. What makes this hexagram unlike anything else in the book is the character that stands in front of the name. The judgment opens with 習坎, and every other figure in the classic is named in its judgment with the name alone. 習 (xí) does double work. Wang Bi reads it as 便習, becoming practiced at a thing: 坎，險陷之名也。習謂便習之. Kong Yingda, in the subcommentary, separates two senses and keeps both: 一者習重也，謂上下俱坎，是重疊有險 — one sense is doubling, since both trigrams are Water and the danger is stacked; 二者人之行險，先須使習其事，乃可得通 — the other sense is training, because a person who has to move through danger must first have become familiar with it. A pit inside a pit, and the second pit is the familiarity.

The verdicts are the harshest of the sequence so far. Misfortune, 凶, is set on the first line and the last. The second and third lines are given no verdict at all: the second is told to seek a small return, the third is told not to act. And no line in Hexagram 29 carries 吉, good fortune, anywhere. The best the figure offers is 无咎, no blame, and it offers that twice, to the fourth line and the fifth. A figure with nothing good in it, and two ways to come out unblamed.

The Sequence explains where the figure sits. 物不可以終過，故受之以坎；坎者陷也 — what cannot stay past its measure forever gives way to the pit, which is why Danger follows Great Excess. Then forward: 陷必有所麗，故受之以離 — whatever falls into a pit must attach itself to something, which is why Fire follows Water. The 雜卦 treats the pair in a single clause: 離上而坎下也, Fire rises and Water sinks.

Structurally this is a doubled figure, one of the eight made of a trigram repeated over itself — 乾, 坤, 坎, 離, 震, 艮, 巽, 兌. Turn it upside down and nothing changes; it is its own reverse. Flip every line, firm for yielding, and 離, Fire, comes out. So the figure has two neighbors rather than one: the same shape read from the other end, and the opposite shape that carries its fire.

Trigram Structure

Water over Water, ䷜, with one firm line at the center of each trigram. Those two firm lines are the whole of the figure's strength, and both are central — 剛中, firm and in the middle. Everything else about the shape says danger: Wang Bi states it flatly, 坎以險為用, danger is what 坎 is for, and the subcommentary names the doubling itself 重險, repeated danger, two pits in file.

The judgment's inwardness follows from the shape. The three characters 維心亨 carry it: the classic restricts the passage to the heart because the firm lines do not show. Wang Bi: 剛正在內，有孚者也。陽不外發而在乎內，心亨者也 — the firm and the correct are on the inside, and that is where the trust comes from; the yang does not reach the outside but stays within, and that is what lets the heart pass. Kong draws the counter-case for contrast: 若外陽內陰，則內心柔弱，故不得亨通 — if the firmness were on the outside and the yielding within, the inward heart would be soft and there would be no way through.

The 彖 gives the figure two images for the same fact. The first is water in a deep pit: 水流而不盈, water flows in and the pit does not fill, which Kong explains as 坑阱特深，水雖流注，不能盈滿 — a trap so deep that water pouring into it never reaches the top. The second is that the water does not stop arriving: 行險而不失其信, it goes through the danger without losing what it holds to. The 大象 takes the arrival, not the depth, as its cue. 水洊至，習坎；君子以常德行，習教事 — water comes and comes again, and so the noble one keeps his conduct steady and rehearses the work of teaching.

The Judgment

習坎：有孚，維心亨。行有尚。

Xí kǎn: yǒu fú, wéi xīn hēng. Xíng yǒu shàng.

Repeated danger. There is trust; the heart alone passes through. To go on carries what is esteemed.

Read character by character:

習 (xí) to practice, to do a thing again and again; here the doubling and the familiarity at once 坎 (kǎn) a pit, a trap; the trigram Water 有 (yǒu) there is 孚 (fú) trust, inward evidence; what holds inside a person 維 (wéi) only, precisely this; it shuts the next two characters off from everything else 心 (xīn) the heart, the seat of the person 亨 (hēng) passage, a way through 行 (xíng) to go, to move 有 (yǒu) there is 尚 (shàng) what is raised up, what is esteemed

The word that carries the sentence is the small one: 維, only. The judgment does not say that the person passes through, or that the work passes through, or that the danger relents. It narrows the passage to the heart and leaves the rest of the picture in the dark — which the subcommentary turns into a description of the figure rather than a promise about it: 內亨外闇, lucid within, dark without.

Jungian reading: the judgment is a statement about where evidence lives. Nothing outside supplies confirmation, since the outside has been declared dark by the structure itself; the only instrument left is the inward one, and the sentence does not apologize for that. Jung's descriptions of the descent through a long disordered passage make the same move, treating the inner center as the sole reliable organ while the outer situation stays unlit. This hexagram is stricter than that. It does not promise that the passage ends in daylight; it says that if anything is going to hold, it will have to hold in there.

The Image

水洊至，習坎；君子以常德行，習教事。

Shuǐ jiàn zhì, xí kǎn; jūn zǐ yǐ cháng dé xíng, xí jiào shì.

Water arriving and arriving again: repeated danger. The noble one therefore gives his conduct a steady course and rehearses the work of teaching.

洊 (jiàn) is arrival upon arrival, one after another. Wang Bi notes that the water does not treat the pit as a wall: 不以坎為隔絕，相仍而至 — it keeps coming. And the reason the Image asks for practice rather than for escape is stated plainly: 至險未夷，教不可廢, while the danger has not been flattened, the teaching cannot be dropped.

Read against the judgment, the Image is doing something exact. The danger in this figure is repetition — the same water arriving, the same pit going unfilled — and the answer offered is a repetition of a different kind: 德行 kept at a constant level, and 教事 rehearsed. What the season does to a person by force, the person can do by choice. The two characters 習 in the Image are the same 習 as in the judgment, and they are the hinge of the page: the figure is drilled into you whether or not you consent, so it is worth choosing something of your own to drill.

The Lines

初六：習坎，入于坎窞，凶。 (Xí kǎn, rù yú kǎn dàn, xiōng.) Repeated danger, and sinking into the hollow at the bottom of the pit. Misfortune.

The bottom line is where the pit is deepest: Wang Bi says 最處坎底 — at the very floor of the doubled danger, and 上無應援, with nothing above that answers or supports it. It is not being blamed for wickedness; 行險而不能自濟, it tries to move through the danger and cannot pull itself out, and the small image states the cause as position: 失道凶也. Some danger is simply where a person is standing.

九二：坎有險，求小得。 (Kǎn yǒu xiǎn, qiú xiǎo dé.) The pit has its peril; seek a small return.

This is the first firm line, and it is out of place — 履失其位, a strong line in a weak seat — with no correspondent above, since the fifth line is firm as well: 上無應援，故曰有險. What it does have is its own centrality, and through that it can reach the two yielding lines beside it: 處中而與初三相得，故可以求小得. Their help is genuine and small, because soft neighbors cannot supply a large rescue: 初三柔弱，未足以為大援. The small image closes the matter with 求小得，未出中也 — a small return, because the line has not yet left the middle of the danger. In practice this is the line's most useful instruction: inside a pit, the assistance that exists is adjacent and modest, and asking it for more than it can give turns the help into a disappointment.

六三：來之坎坎，險且枕，入于坎窞，勿用。 (Lái zhī kǎn kǎn, xiǎn qiě zhěn, rù yú kǎn dàn, wù yòng.) Coming or going, pit after pit; danger, and no rest in it; sinking into the hollow at the bottom. Do not act.

The third line is out of place and sits at the top of the lower trigram, at the seam between the two, so both directions fail: 出則之坎，居則亦坎, step out and it is a pit, stay and it is the same one. Wang Bi reads 枕 as 枕枝而不安, propped up and unsteady rather than at rest, and draws the conclusion without ornament: 來之皆坎，無所用之，徒勞而已 — the effort spends itself and returns nothing. The small image agrees: 終无功也. This is the figure's warning about the move made because stillness has become unbearable. The instruction is the plainest negative in the hexagram: 勿用, no use.

六四：樽酒簋貳，用缶，納約自牖，終无咎。 (Zūn jiǔ guǐ èr, yòng fǒu, nà yuē zì yǒu, zhōng wú jiù.) A jug of wine, two baskets of grain, served in earthenware, passed in at the window: in the end, no blame.

The fourth line stands in danger but stands correctly — yielding in a yielding place, 以柔居柔，履得其位, directly beneath the ruler, with neither out of place: 剛柔各得其所，不相犯位. Wang Bi's point is that the plainness is the evidence rather than a failure of means: 明信顯著，不存外飾, what is evident and true does not depend on outer decoration. One jug, two baskets, clay vessels, brought to the window — and the commentary says such an offering is still fit for a ruler or for the ancestral hall: 可羞之於王公，薦之於宗廟. The small image names the reason in four characters, 剛柔際也, and Wang Bi glosses 際 as contact and accord: 剛柔相比而相親焉，際之謂也. This is the only line in the hexagram whose subject is told 終, at the end: not relief now, but no blame at the end. The way through is what actually exists, offered through the opening that actually exists.

九五：坎不盈，祗既平，无咎。 (Kǎn bù yíng, zhī jì píng, wú jiù.) The pit is not filled; only when the leveling is done is there no blame.

The ruler's seat is inside the pit and has no helper: 為坎之主而無應輔可以自佐，未能盈坎者也 — the one who governs the pit cannot fill it alone. And an unfilled pit means the danger is unfinished: 坎之不盈，則險不盡矣. Wang Bi reads 祗 as a particle, not a word with content, which leaves the line saying exactly this: 盡平乃無咎, no blame only when it is entirely leveled — and then he draws out what the phrasing concedes, 明九五未免於咎也, which is to say the fifth line has not escaped blame yet. Kong adds the reason it cannot: 雖復居中而無其應，未得光大 — central, but unanswered, and therefore not yet enlarged. Some editions read 祗 as 坁, a small mound; the reading changes the picture, not the unfinished arithmetic. Anyone who manages a long difficulty and mistakes holding it for finishing it should read this line twice.

上六：係用徽纆，寘于叢棘，三歲不得，凶。 (Xì yòng huī mò, zhì yú cóng jí, sān suì bù dé, xiōng.) Tied with black cords, set down among thorns, three years without finding it. Misfortune.

The top of the doubled danger is a height nobody can climb: 險峭之極，不可升. Wang Bi describes the place as strict and unbreakable, 嚴法峻整，難可犯也, and says the fitting condition there is confinement where a person has to think the matter through: 宜其囚執寘於思過之地. Then he gives the number its sense. 三歲，險道之夷也 — three years is the time it takes the dangerous road to flatten; 險終乃反，故三歲不得自脩，三歲乃可以求復 — the danger ends and turns back, so for three years no self-correction is available, and after three years recovery may be sought. The small image keeps the term in view: 上六失道，凶三歲也, and Kong adds 言失道之凶，唯三歲之後可以免也. The last line of the figure is a closed door with a date on it. Nothing shortens the time, and nothing but self-repair uses it.

How This Hexagram Shows Up in Daily Life

The first thing to get right is which of the two 習 is in play. A season that keeps arriving is the subject of the hexagram; a difficulty a person has merely grown used to is its trap. The difference shows up in the sentence a person repeats. If the same problem returns in the same form with a different date on it, the pit is filling itself again and the depth is the issue. If the problem has not changed but has become comfortable — familiar, expected, budgeted for — that is 便習 in its second sense, and the danger has moved inside the person. Kong keeps both senses in one commentary because the figure needs both: familiarity is the skill that gets you through, and familiarity is also the thing that keeps you in.

The middle lines' instructions are the ones most people can use on a Tuesday. 求小得 is the second line's whole counsel: in a pit, the available help is adjacent, small, real, and enough to move one step. The response it rules out is demanding a large rescue from small hands — from the two soft lines that stand nearest. And 勿用 is the third line's, aimed at the move made because waiting has become intolerable. Between them the figure draws a line that most crises do not respect: take the small thing that is offered, and do not take the step that is only a complaint about standing still.

The last three lines are about manner and term. 六四 gets through by bringing what it actually has through the one opening it actually has, plainly, since the plain version is the one that cannot be caught out. 九五 warns that holding a difficulty is not the same as ending it: no blame only when the leveling is done. 上六 puts a number on the consequences of a wrong road: three years, with self-repair as the only thing that uses them well.

Frequently Asked Questions

What does Hexagram 29 mean in one sentence?

That danger has become the medium rather than the event: the pit is doubled, water keeps arriving and never fills it, no line in the figure is judged good fortune, and the only passage the judgment allows is inward — 有孚，維心亨 — with the going itself still worth something even while the outside stays dark.

Why is this hexagram called 習坎 and not simply 坎?

Because it is the only figure whose judgment prefixes the name, and the prefix carries two senses that Wang Bi and Kong Yingda both keep. 一者習重也，謂上下俱坎 — the doubling, since both trigrams are Water; and 二者人之行險，先須使習其事，乃可得通 — practice, since anyone moving through danger has first to become familiar with it. A pit inside a pit, and the second one is the familiarity.

What does 有孚，維心亨 mean, and why does only the heart get through?

孚 is inward evidence — what holds inside a person rather than what is confirmed from outside; 維 restricts the passage to the heart, 心亨, and the restriction comes from the shape. Wang Bi: 剛正在內，有孚者也。陽不外發而在乎內，心亨者也. The figure's firmness does not show, so the outside stays dark — 內亨外闇 — and the judgment makes no promise that it will brighten. What it says is that the passage, if there is one, is inside.

What is 樽酒簋貳，用缶，納約自牖 — the plain offering of the fourth line?

A jug of wine, two baskets of grain, clay vessels, passed in at the window. The fourth line stands correctly in a dangerous place and sits directly beneath the ruler, so the plainness is not poverty but evidence: 明信顯著，不存外飾, what is true does not need outer decoration, and the commentary holds that such an offering can still be presented to a ruler or at the ancestral hall, 可羞之於王公，薦之於宗廟. The window matters as much as the vessels. The offering goes through the opening that exists rather than the door that does not, and the line's verdict is the only one in the figure that reaches 終, at the end: 終无咎.
