The name 名
Kǎn 坎 is a pit, water, danger. Of the eight doubled trigrams only this one takes an extra character, Xí 習. Cheng Yi read it as “repeated”: danger within danger. It also means “to practise”: where danger abounds one must train until one can walk through it as on level ground.
The image 象
Water over water: in each trigram a yang line is sunk between two yin, like a current in a ravine, danger following danger. Yet water keeps moving day and night and never stops to fill the pit, always true to its nature. All three lower lines are out of place and all three upper lines in place, so within the same danger the lower and upper situations differ greatly.
Layers of images 層
A gua can be read on several levels at once: the trigrams as members of a family (father, mother, eldest to youngest sons and daughters), the six lines as ranks in an organisation (from newcomer to ruler), and as forces of nature and animals. Each extra level adds meaning to the line texts.
Read as a family
The Shuo Gua makes Kǎn the middle son: one yang line squeezed between two yin, like the middle child with an elder above and younger ones below, pressed from both sides and easily overlooked. Here the middle son is doubled, danger upon danger. Yet the yang at the centre stays solid: pits all around, but a firm core within, which is why the judgment says “only the heart gets through.”
Line 4, “a jug of wine, two bowls of grain, in plain earthenware, handed in through the window”: lines 2–4 form a nuclear Zhèn, spring and green growth, so the offering is only spring vegetables, a jug of wine and two bowls, served in clay. The fourth place is the minister beside the ruler; in danger he skips the grand gate and passes his sincerity to Line 5 through a window: simple form, real intent, and in the end no blame.
Line 5, “the pit is not overfilled; it is only levelled”: Line 5 is central and correct, the ruler inside the danger. As long as water keeps flowing and does not overfill, there is no flood; level the pit and leave it there, without aiming for perfection. A leader who stays even in a crisis, neither grabbing credit nor pushing too far, commits no fault.
Top line, “bound with black cords, put among thorn bushes, three years without release”: the Shuo Gua calls Kǎn a wood “hard with much heart,” thorny timber, hence the thicket; Kǎn is also fetters. So one is tied up and held in a prison fenced with thorns. Reaching the end of danger and still refusing to wake up means a long confinement.
Change all six lines of Kǎn and you get Lí. Kǎn is a yang trapped between yin, soft outside and firm within; Lí is a yin clinging between yang, firm outside and soft within. Kǎn teaches holding to inner substance in danger; Lí teaches clinging to what is bright. When stuck in Kǎn, look at Lí: the other face of a crisis is learning to use the light and see the way.
Lines 2–5 of Kǎn make the nuclear hexagram Yí, Nourishment. Inside the layered pits lies the question of nourishment: in hard times, watch even more closely what you take in and what you say. Carelessness with words and food is what drags people deeper.
In sequence 序
物不可以終過，故受之以坎；坎者陷也。
The Sequence says things cannot keep passing beyond forever, hence the Abyss follows Great Excess; kǎn means to sink. Great Excess overreached, or passed through; after that comes the pit, a check that makes one pause and face limits.
The judgment 辭
習坎：有孚，維心亨。行有尚。
“The Abyss, doubled: there is sincerity; through the heart there is success; action earns esteem.” The two yang lines hold the central places, and the centre stands for the heart, solid and trustworthy. The word “heart” rarely appears in the Judgments. In danger, what carries one through is not luck but inner good faith.
Commentary on the judgment 彖
彖曰：習坎，重險也。水流而不盈，行險而不失其信。維心亨，乃以剛中也。行有尚，往有功也。天險不可升也，地險山川丘陵也，王公設險以守其國，坎之時用大矣哉！
The Tuan: water flows without overfilling and passes through danger without losing its faithfulness; success through the heart comes from strength at the centre. It distinguishes the dangers of heaven, which cannot be scaled; of earth, mountains, rivers and hills; and those that rulers set up to guard the state, its laws and defences. Danger cuts both ways, and one who can use it is wise: great indeed is the timely use of the Abyss.
The great image 象
象曰：水洊至，習坎；君子以常德行，習教事。
“Water flows on and on: the Abyss, doubled. The noble person keeps virtue constant and practises the work of teaching.” Water arrives in unbroken succession; so should self-cultivation, without the step forward and two steps back that undo it, persevering like a river day and night.
The six lines 爻
Ruling line The fifth line, central and correct, governs the gua. The second line is also a central yang line but out of place and still trapped; of the two, the fifth rules.
The path of the six lines, bottom to top
Line 1 falls straight into a pit within the pit: misfortune. Line 2 is still in danger, but central and solid, it seeks only small gains. Line 3 has pits ahead and behind, danger coming and going; better to stop and not burrow deeper. Line 4 enters the upper trigram and passes simple wine and food through a window, getting through by sincerity, not ceremony. Line 5: the water does not overflow, the pit is levelled; the crisis is passing and no credit is grabbed. The top line, lost to the end, is bound with cords among thorns, unable to get free for three years.
初六習坎，入于坎窞，凶。
In plain words
In the doubled abyss, falling into the pit within the pit: misfortune.
Close reading
A yin line in a yang place, with no partner in the fourth line, and the second line above is trapped itself. At the very bottom under two layers of danger, it feels them most; only here does the phrase “doubled abyss” recur. The pit within the pit is danger inside danger. The Small Image says misfortune comes from losing the way.
If you drew this line
There is no opening now. Don't press forward; steady yourself and find your bearings first.
九二坎有險，求小得。
In plain words
In the abyss there is danger; seek small things and you will gain.
Close reading
Out of place but central, and centrality counts for more than correctness. It has no partner in the fifth line and is wedged between two yin lines, not yet free. The line below supports it, so seeking small things brings gain. The Small Image says it has not yet left the midst of danger: aim small, not large.
If you drew this line
Settle for modest gains within your means. Don't envy others' windfalls; secure what is actually within reach.
六三來之坎坎，險且枕，入于坎窞，勿用。
In plain words
Coming and going, pit upon pit; danger, and layer upon layer; fallen into the pit within the pit. Do not act.
Close reading
A yin line in a yang place with no partner, it has just left the lower pit and faces the upper one: back is danger, forward is danger. “Layer upon layer” means danger piled as on a pillow. It sits in both an inner Thunder and an inner Mountain, movement and stillness pulling against each other. The text says only “do not act”; stay still and you avoid great harm. The Small Image warns that any action ends without result.
If you drew this line
Trapped either way, the best action is none. Keep safe and wait for the situation to shift.
Jung's Foreword
When Carl Jung wrote the foreword to the English edition of Richard Wilhelm's I Ching, he consulted the book about his own undertaking. He received the Abyss with the six in the third place moving, changing to the Well. Jung admitted the fit: presenting a Chinese book of divination to Western readers who had never encountered it was danger on every side, with little hope of understanding. As for the Well it changed into, a spring that never runs dry and serves all who draw from it, one may read it as the old book waiting to be drawn upon.
六四樽酒簋貳，用缶，納約自牖，終无咎。
Variant Shown as 「樽酒簋貳，用缶，納約自牖」; some editions read 「尊酒簋，貳用缶，内約自牖（朱子句讀：樽酒簋，貳用缶）」.
In plain words
A jug of wine, a bowl of grain, with plain earthenware; the simple offering passed in through the window. In the end, no blame.
Close reading
A yin line correctly placed, without a partner below but right beside the ruler in the fifth line, the soft serving the strong; the Small Image calls it the meeting of firm and yielding. As the minister nearest the throne, it must be measured and win trust by sincerity. A gui is a ritual grain vessel, a fou a clay pot, the window a humble passage: no display, only good faith. Having escaped the lower pit, it steadies itself through simple reverence and is blameless in the end.
One level deeper
Line 4, “a jug of wine, two bowls of grain, in plain earthenware, handed in through the window”: lines 2–4 form a nuclear Zhèn, spring and green growth, so the offering is only spring vegetables, a jug of wine and two bowls, served in clay. The fourth place is the minister beside the ruler; in danger he skips the grand gate and passes his sincerity to Line 5 through a window: simple form, real intent, and in the end no blame.
If you drew this line
Approach those above you simply and sincerely, without display. Plain good faith wins more trust than ceremony or tactics.
Offerings Beneath the Window
In the ode “Gathering Duckweed” from the Book of Songs, a young woman about to marry gathers water plants, cooks them and sets them out, then lays the offering “beneath the window of the ancestral hall,” presided over by “the reverent youngest daughter.” Before marriage a young woman honoured the ancestors at the window with simple offerings, where what mattered was sincerity, not abundance. The line's image of passing a simple offering through the window belongs to the same world.
九五坎不盈，祗既平，无咎。
Variant Shown as 「祗既平」; some editions read 「禔」.
In plain words
The abyss does not overflow; it fills only to the level. No blame.
Close reading
Central and correct, the ruling line echoes the Tuan's “water flows without overfilling”: moving water does not brim but settles at its level. Yet it is hemmed between two yin lines and has no partner in the second, so its strength is not yet great; the Small Image says its centrality is not yet grand. In a gua of danger, to be without blame is already a good result.
One level deeper
Line 5, “the pit is not overfilled; it is only levelled”: Line 5 is central and correct, the ruler inside the danger. As long as water keeps flowing and does not overfill, there is no flood; level the pit and leave it there, without aiming for perfection. A leader who stays even in a crisis, neither grabbing credit nor pushing too far, commits no fault.
If you drew this line
Keep things level rather than full. Holding steady is the achievement now; don't overreach or inflate your position.
上六係用徽纆，寘于叢棘，三歲不得，凶。
In plain words
Bound with cords and ropes, placed among thorn hedges; for three years no release. Misfortune.
Close reading
Correctly placed, yet at the extremity of the doubled abyss with nowhere to go, riding over the ruler and lacking a partner, it is deep in danger without knowing it. The Abyss has the image of a prison: hui and mo are cords of three and two strands, and thorn hedges enclosed the ancient lock-up. The Small Image says it has lost the way and suffers for three years. Three years is a long while, and also a limit after which things change.
One level deeper
Top line, “bound with black cords, put among thorn bushes, three years without release”: the Shuo Gua calls Kǎn a wood “hard with much heart,” thorny timber, hence the thicket; Kǎn is also fetters. So one is tied up and held in a prison fenced with thorns. Reaching the end of danger and still refusing to wake up means a long confinement.
If you drew this line
You are bound for now, and struggling only tightens the knots. Accept the situation, examine your missteps, and endure a long stretch with patience.
The Three-Year Term in the Zhou Rites
The Rites of Zhou (Autumn Offices, Si Yuan) record that unruly people were held and taught; those who reformed were released, the gravest offenders after three years, while those who would not reform and escaped the enclosure were put to death. There was no lifelong imprisonment; three years was the span given to change. “Three years without release” is thus not only hardship but a time for reflection.
Stories 典
The White Streak in the Waves
A woodcutter climbs the mountain daily and moves swiftly along steep paths; a city visitor on the same trail gasps and stumbles. In the Water Margin, Zhang Shun, nicknamed “White Streak in the Waves,” moves through the river as easily as on dry land, while most people who fall in grab for anything that floats. The difference is not birth but practice. That is the Xí in Xí Kǎn: danger is everywhere, and a world without risk would not be the human world. Rather than flee it, practise until you walk through danger as on level ground.
Forty Years in the Wilderness
The journey from Egypt to Canaan is not long, yet according to the Book of Numbers the Israelites wandered forty years in the wilderness; nearly the whole generation that left Egypt died on the way, and even Moses only saw the promised land from afar. Those who entered were a new generation raised in the desert. The story is often told to show how hard old habits are to shed: the hardest farewell is to one's former self. The Image's “keep virtue constant and practise teaching” asks for cultivation that flows without pause and never slides back.
Insight 悟
Of the four hexagrams of hardship this is the most dangerous: the first and last lines are ill-fated and not one line is called fortunate. Yet the Judgment insists on sincerity and success through the heart. Outer danger cannot be abolished; what one controls is inner good faith and steady cultivation. Danger has its uses: whoever has been tested again and again meets later trials with ease, and a crisis prepared for becomes a turning point. When you draw this gua, see where you stand: in the lower trigram, keep still; in the upper, act with sincerity and balance, and count blamelessness as success.
