The name 名
Gèn 艮 is the mountain, which stands unmoving, so its root sense is ‘stop’. One yang line sits atop two yin like an upturned bowl: the yang has reached the top and halts. Gen is also ‘hard wood with many knots’, like the jointed spine; since the ancients took the spine as the body's midline, the back became the emblem of stillness.
The image 象
Mountain upon mountain. Travellers of old halted at a mountain; how much more at a range beyond a range. Yet inside lie a hidden Water (lines 2–4) and a hidden Thunder (lines 3–5): peril and motion folded into stillness. Gen is not mere immobility but the discernment of when to stop and when to go. It is Zhen turned upside down—motion and rest, each completing the other.
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
Gèn is the youngest son above and below. Counting from the bottom, the third yang line, the top one, makes Gèn the youngest son, with the two yin lines below as its setting. The youngest son does not inherit, so Gèn is not about succession, as Zhèn is, but about stopping: the mountain blocks the road, the hand holds others back. “Brothers are like hands and feet”: Zhèn is the foot that walks on, Gèn the hand that knows how to hold back.
Line 3, “stopping at the waist, tearing the flesh along the spine; danger smoulders in the heart”: this is the line that makes the lower Gèn the youngest son, and it sits at the waist, the divide between upper and lower body. Yet it is yang in a yang place, eager to move, and inside the nuclear Zhèn of lines 3–5, walking, so one half wants to stop and the other to go. It is also in the nuclear Kǎn of lines 2–4, heart-sickness: the back is torn and the heart burns.
Top line, “steadfast stopping; good fortune”: it too is a youngest-son line, at the top of the upper Gèn and the summit of the whole figure. Line 3 forces a stop halfway and suffers; the top line stops naturally at the peak, solid and settled, and it is the only line of the six that says “good fortune.” Stop where stopping belongs, and it does not hurt.
The judgment, “stopping at the back, he does not grasp his body; walking in the courtyard, he does not see the person”: two Gèn trigrams are two gates with a courtyard between; the nuclear Zhèn of lines 3–5 is walking, so someone crosses the courtyard; the nuclear Kǎn of lines 2–4 is hiding, so no one is seen. Gèn comes from Guān, whose lower Kūn, the mother who “has a body,” has disappeared, so even attachment to one’s own body is let go.
Line 5, “stopping the jaws; words in order; regret vanishes”: in speech the upper jaw stays still and the lower moves. Line 5 sits in the upper Gèn, so it can stop, and in the nuclear Zhèn, so it can move; when stopping and moving work together, words come out in order. Line 3 is too hard to stop and tears; Line 5, yin in a yang place, blends firm and soft and stays in balance.
Turned over, Gèn becomes Zhèn: the youngest and eldest sons, one still and one moving, brothers in hardship. Zhèn is about keeping calm after taking over; Gèn about settling down when you need not step forward. Read side by side, they show that stopping is not passivity but the other half of movement.
Gèn’s nuclear trigrams are Kǎn below and Zhèn above, making Xiè, Release. The inner process of stopping is untying: only when a person is still do the knots loosen. Like sitting quietly or taking a day off: on the surface nothing is done, while inside things are being worked out.
In sequence 序
物不可以終動，止之，故受之以艮；艮者止也。
The Sequence says things cannot move forever; they must be brought to rest, so Gen follows. Zhen was motion; no motion can go on without end, and stillness takes its turn.
The judgment 辭
艮：艮其背，不獲其身，行其庭，不見其人，无咎。
Keeping still the back, one does not see the other's body; walking through the courtyard, one does not see the person there. No blame. Both trigrams face forward with their backs behind, like people in a queue who see only the back ahead: no one faces anyone, and desire has nothing to seize on. Gen derives from Guan (20) by swapping lines 3 and 5; the lower Kun—mother, the one who can ‘carry a body’—disappears, hence ‘not getting the body’. The hidden Thunder is a walker, the two Mountains are two gate-towers with a courtyard between, and the hidden Water means concealment: one crosses the court and sees no one. Self-restraint of this degree is naturally without blame.
Commentary on the judgment 彖
彖曰：艮，止也。時止則止，時行則行，動靜不失其時，其道光明。艮其止，止其所也。上下敵應，不相與也。是以不獲其身，行其庭不見其人，无咎也。
‘When it is time to stop, stop; when it is time to go, go. Movement and rest not missing their moment—its way is bright.’ Gen's stopping includes action; the key is timing. ‘Stopping in its place’ adds the spatial dimension: time and position must both be right. Every doubled trigram lacks correspondences, but only here does the Commentary point it out—‘upper and lower oppose, not joining’—because stillness means not being pulled by another.
The great image 象
象曰：兼山，艮；君子以思不出其位。
Mountains joined: Gen. The noble person does not let their thoughts go beyond their position. Think through and do well what your station asks of you; a different station brings a different vantage, and the thinking will change with it.
The six lines 爻
Ruling line The top line rules: Gen's single yang sits on top, and a mountain is judged by its peak—the mirror of Zhen, where the bottom line rules. It is also the only auspicious line. Line 3 is not the ruler but is essential to the lower Mountain.
The path of the six lines, bottom to top
Line 1 stops at the toes, before taking a step; steady over time, it is blameless. Line 2 stops at the calves but cannot rescue Line 3, which it follows, and its heart is unhappy. Line 3 stops at the waist, forcing stillness so hard that the flesh along the spine tears: the most painful moment of the hexagram. Line 4 enters the upper trigram and stops the trunk, holding the self still: no blame. Line 5 stops the jaws, and its words are orderly; regret goes. The top line stops with solid weight at the summit, naturally and auspiciously: here stillness is finally complete.
初六艮其趾，无咎，利永貞。
In plain words
Keeping the toes still. No blame. It is fitting to remain steadfast for long.
Close reading
A yin line in a yang place, out of position; at the very bottom, without response from line 4, it has neither help nor strength to move. In a time of stillness, halting before the first step is exactly right—‘it has not lost what is correct’. Better one thing fewer than one thing more.
If you drew this line
Before anything has begun, hold your position and keep to your part. Long, steady correctness is safer than a hasty start.
六二艮其腓，不拯其隨，其心不快。
In plain words
Keeping the calves still, yet unable to halt what they follow. The heart is not glad.
Close reading
A yin line in a yin place, central and correct, it ought to stop as the time requires; but a calf cannot move on its own—it goes where the thigh (line 3) goes. Before the change, this line corresponded with line 5 of Guan; when that yang line came down to third place, the partner was lost. Line 3, caught in the hidden Thunder, wants to move and will not step back to listen—‘it has not withdrawn to heed’. It is rare for a line both central and correct to be so badly placed. Both this line and line 3 mention the heart: a wish that cannot be carried out.
If you drew this line
You want to stop, but a superior or the larger current carries you along, and you chafe. Sort out what is yours to decide and what is not; neither blame yourself nor fight it head-on.
九三艮其限，列其夤，厲薰心。
In plain words
Keeping the waist still, tearing the flesh along the spine. Danger; the heart is smothered in smoke.
Close reading
A yang line in a yang place, correctly placed and full of drive. It sits at the seam between the two Mountains, where stopping is unavoidable, yet it is caught in the hidden Thunder that wants to move. Halt and go pull against each other, and the back is torn. Xian is the waist, the boundary between upper and lower body; yin is the flesh along the spine, from the hidden Water's image of a fine back. Water also means anxiety and heart trouble—hence ‘the heart is smothered’. Cheng Yi's verdict: unable to stop or go according to the time, fixed rigidly on one course, one becomes perverse in the world and cut off from others.
One level deeper
Line 3, “stopping at the waist, tearing the flesh along the spine; danger smoulders in the heart”: this is the line that makes the lower Gèn the youngest son, and it sits at the waist, the divide between upper and lower body. Yet it is yang in a yang place, eager to move, and inside the nuclear Zhèn of lines 3–5, walking, so one half wants to stop and the other to go. It is also in the nuclear Kǎn of lines 2–4, heart-sickness: the back is torn and the heart burns.
If you drew this line
Caught between two pulls, do not lock yourself into one rigid course and grit your teeth. Let timing adjust when you stop and when you go, and the inner torment eases.
六四艮其身，无咎。
In plain words
Keeping the trunk still. No blame.
Close reading
A yin line in a yin place, correctly placed, able to go with the time and hold itself still—‘it stops in its own person’; the body here is simply the self. Above the waist, near the heart, it restrains the whole upper body: self-control in conduct. It earns only ‘no blame’, not good fortune, because it rides the hard line 3. As Confucius said, few go wrong through restraint.
If you drew this line
Govern your own conduct and stay within bounds, and all will be well. Now restraint matters more than achievement.
六五艮其輔，言有序，悔亡。
In plain words
Keeping the jaws still. Words come in good order. Regret vanishes.
Close reading
A yin line in a yang place, out of position and without response from line 2, so regret is natural; but it holds the centre of the upper trigram—‘because it is central and correct’, where centrality is the point. Fu is the upper jaw; when the jaw does not move rashly, speech keeps its measure. Sitting in the upper Mountain and also in the hidden Thunder, it can both stop and move, firmness tempered by softness: hence ‘words in good order’. Line 3 also stands between Mountain and Thunder but, too hard, is torn apart—the two lines make a telling pair.
One level deeper
Line 5, “stopping the jaws; words in order; regret vanishes”: in speech the upper jaw stays still and the lower moves. Line 5 sits in the upper Gèn, so it can stop, and in the nuclear Zhèn, so it can move; when stopping and moving work together, words come out in order. Line 3 is too hard to stop and tears; Line 5, yin in a yang place, blends firm and soft and stays in balance.
If you drew this line
Guard your words: speak when it is time, keep silent when it is not, and say things in order. Regret will fall away of itself.
Three Faults in Speaking Before One's Betters
In the Analects, Confucius names three faults of one who attends a superior: to speak before it is one's turn is rashness; not to speak when it is one's turn is concealment; to speak without watching the other's face is blindness. They are failures of timing, of responsibility and of perception. ‘Words in good order’ does not mean saying less; it means speaking at the right moment and in the right measure.
上九敦艮，吉。
In plain words
Keeping still with solid steadfastness. Auspicious.
Close reading
A yang line in a yin place, out of position, yet atop the double mountain and ruler of the gua; a mountain is weighed by its summit, and stillness at the end is at its weightiest. ‘Ending in solidity’: to close with weight and depth fulfils what Gen asks. That this is the only auspicious line shows how hard a good ending is.
One level deeper
Top line, “steadfast stopping; good fortune”: it too is a youngest-son line, at the top of the upper Gèn and the summit of the whole figure. Line 3 forces a stop halfway and suffers; the top line stops naturally at the peak, solid and settled, and it is the only line of the six that says “good fortune.” Stop where stopping belongs, and it does not hurt.
If you drew this line
Late in an undertaking, be steady, low-key and solid. Finishing with weight is worth more than one last gamble.
The Child Changing Schools
A parent, planning to move a bright, outgoing child—popular at the old school—to a new one, worried about how the child would adjust and cast this line. Two mountains stacked, the top one highest: as steady as Mount Tai. The advice was to keep a low, steady profile in the first year—learn the place, catch up on the work, get along with classmates—and things would go well afterwards. Six months later the parent reported that the child had made many new friends. It is common sense; the value of a casting often lies in reminding us of conduct and measure.
Stories 典
Not in the Office, Not in Its Counsels
The Analects twice records Confucius saying that one not in an office should not plan its affairs. In one passage Master Zeng adds at once: the noble person's thoughts do not go beyond their position—Gen's Great Image word for word, minus a single particle. The Commentaries and the Confucian circle clearly share one line of thought, and the disciples very likely discussed the Changes. The saying is no counsel of timidity. It reminds us to think through and do well what is ours; from outside a position one cannot see all it involves, and meddling only adds confusion.
Three Years Silent, Then One Cry
The Analects cites the Book of Documents: King Wuding of Shang, in mourning, did not speak for three years. The Records of the Grand Historian tells how King Wei of Qi, newly enthroned, gave himself to feasting and neglected the state, until Chunyu Kun posed him a riddle: a great bird in the kingdom has neither flown nor sung for three years—what bird is it? The king answered that once it flies it will soar to heaven, once it sings it will astonish all. He then summoned his county magistrates, rewarded one, executed one, and marched out, and the other states were shaken. Between stillness and action, what is needed is exactly this judgement of when to stop and when to go.
Insight 悟
Gen is the wisdom of stopping, but stopping is not stagnation: movement and rest must keep their time, and stillness must find its place. The hard part is seldom starting; it is knowing when to halt. Line 3 clings to one course and its heart burns; line 5 blends firm and yielding and its words come in order; the top line ends with weight and is blessed. Keeping one's thoughts within one's position is not timidity but first thinking through and doing well what is one's own. Only one who knows how to stop leaves room to move.
