The name 名
Yù 豫 carries two meanings: delight, and preparation, in which sense it is interchangeable with 預. When a disciple asks Mencius why he looks “not 豫,” he means displeased. The gua holds both senses at once: in times of joy, be careful, or the joy will not last.
The image 象
Zhèn above is thunder and movement; Kūn below is earth and compliance. Spring thunder bursts from the ground and everything stirs to life, hence delight; yielding below and moving above is “moving in accord.” The Xici adds that double gates and the night watchman’s clapper, set “to await raiders,” were drawn from this gua: readiness inside the ease.
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
Below is Kūn, the mother; above is Zhèn, the eldest son. The eldest son steps out in front and takes action, and the mother and the many follow gently below, like the first spring thunder waking every living thing and filling it with gladness. The only yang line, Line 4, holds the whole situation together, but it sits in the fourth place, not on the throne: what makes everyone glad is a minister holding real power.
Line 4, “the source of enthusiasm; much is gained; do not doubt; friends gather like hair in a clasp”: the fourth is a minister’s place, yet here it is the ruling line of the whole hexagram, and all five yin respond to it. It sits in the nuclear Kǎn of lines 3–5, which is doubt, so the text says “do not doubt”: deal with people in full sincerity, and friends gather like hair held by a pin.
Line 5, “chronically ill, yet it does not die”: Line 5 holds the throne but rides on Line 4, who has the real power: title and strength are split apart, like a long illness. It is also in the nuclear Kǎn, the troubled heart. But it is central, and the upper Zhèn stands for life springing back, so it is ill but does not die: an awkward position that can nonetheless endure.
Line 2, “firm as a rock; not even a whole day; steadiness is fortunate”: lines 2–4 form a nuclear Gèn, stone and stopping. Line 2 is still far from the top of that Gèn, yet it already stops while everyone else is lost in pleasure, waking up before the day is out. Compare Line 3, “gazing up for pleasure; delay brings regret”: it stops only when it is almost at the top, too late. Within the same Gèn, stopping early or late makes all the difference.
Change all six lines of Yù and you get Xiǎo Xù, Small Restraint. In Yù one yang leads and the many yin follow gladly, energy let out; in Xiǎo Xù one yin restrains the many yang, energy held in. The hidden side of enjoyment is restraint: thinking of holding back in the middle of pleasure keeps one from the top line’s fate of revelling into the dark.
In sequence 序
有大而能謙，必豫，故受之以豫。
The Sequence says: “Having much and being able to be humble, one is sure to be at ease; hence Delight follows.” Great Possession supplies abundance, Humility the restraint to carry it; together they bring contentment. Yù is also Qiān turned upside down.
The judgment 辭
豫：利建侯行師。
The Judgment is a single phrase: “Delight: favourable for establishing lords and setting armies in motion.” The fourth line stands in Zhèn, movement, above Kūn, the multitude, and a multitude can become an army. Founding states and raising troops are weighty matters, but when the time is ripe and people are willing, what must be done should be done.
Commentary on the judgment 彖
彖曰：豫，剛應而志行，順以動，豫。豫，順以動，故天地如之，而況建侯行師乎？天地以順動，故日月不過，而四時不忒；聖人以順動，則刑罰清而民服。豫之時義大矣哉！
The Commentary: “The firm is answered and its will is carried out; moving in accord.” The single hard line is echoed above and below. Heaven and earth move in accord, so sun and moon keep their course and the seasons do not err; the sage moves in accord, so punishments are clear and the people are won over. Its closing cry, “Great indeed is the meaning of the time of Delight!”, is the first of about a dozen such exclamations on timing in the Commentary.
The great image 象
象曰：雷出地奮，豫。先王以作樂崇德，殷薦之上帝，以配祖考。
“Thunder comes out of the earth, rousing: Delight. The former kings composed music to honour virtue, and offered it in solemn rites to the Lord on High, with their ancestors as companions.” The subject is the former kings rather than the noble person. In good times joy naturally becomes music, but music must serve virtue or it slides into indulgence; and prosperity calls for gratitude toward the source of all things and the source of one’s own life.
The six lines 爻
Ruling line The fourth line, the only yang line, is answered by all five yin lines; the gua’s delight flows from it, so it rules. Being yang in a yin place, it is not correctly positioned, and its rule is not effortless.
The path of the six lines, bottom to top
Line 1 crows with pleasure from the very start, showing off its link to Line 4, and that is ominous. Line 2 is steady as rock: while others indulge, it wakes before the day is over, central and upright, and fortunate. Line 3, at the top of the lower trigram, looks up to Line 4’s face for its pleasure; waking late brings regret. Entering the upper trigram, Line 4 is the source of everyone’s gladness: sincere and free of doubt, it draws friends together. Line 5, above Line 4, has the title without the power, chronically ill yet not dying; at the top, pleasure has run into the night, yet if one is still willing to change, there is no blame.
初六鳴豫，凶。
In plain words
Delight that cries out; misfortune.
Close reading
Yin in a yang place, out of position and weak, yet corresponding with the ruling fourth line; it has reached the centre of power at the very first step, and so “cries out” in delight. The gua has barely begun, nothing above is yet clear, and already it wants pleasure all the way. The Small Image: “its aim is exhausted; misfortune.” Ambition spent at the starting line is where trouble begins.
If you drew this line
Elation at the first good sign is the most dangerous moment. Rein in the celebration, keep working, and do not mistake the start for the finish.
Happy here, not missing Shu
After Shu Han fell, its last ruler, Liu Shan, was moved to Luoyang. At a banquet Sima Zhao had the music and dances of Shu performed; the former ministers of Shu were all stricken, while Liu Shan laughed along. Asked whether he missed Shu, he replied, “I am happy here; I do not miss Shu.” When pleasure comes too easily, purpose disappears with it: the first line’s “aim exhausted.”
六二介于石，不終日，貞吉。
In plain words
Firm as a rock; not waiting out the day; steadfastness brings good fortune.
Close reading
Yin in a yin place, central and correct, with no response from the fifth line and no adjacency to the fourth: the one line that does not attach itself to the ruler, and the only one whose text lacks the word 豫. It sits at the base of the inner Gèn (lines two to four), stopping and small stones, hence “firm as a rock”; still far from Gèn’s stopping point, it stops already, hence “not waiting out the day.” The Small Image: “because it is central and correct.” The Xici has Confucius say: “The first sign is the slightest stirring of movement, the earliest glimpse of good fortune. The noble person sees it and acts, without waiting out the day.”
One level deeper
Line 2, “firm as a rock; not even a whole day; steadiness is fortunate”: lines 2–4 form a nuclear Gèn, stone and stopping. Line 2 is still far from the top of that Gèn, yet it already stops while everyone else is lost in pleasure, waking up before the day is out. Compare Line 3, “gazing up for pleasure; delay brings regret”: it stops only when it is almost at the top, too late. Within the same Gèn, stopping early or late makes all the difference.
If you drew this line
When everyone is chasing pleasure, hold to your own principles. Read the direction from the smallest signs, and stop or act at once; there is no need to wait.
Jieshi and Zhongzheng
The modern Chinese leader Chiang Kai-shek took the formal name Zhongzheng and the courtesy name Jieshi, and both are generally traced to this line: “firm as a rock” (介于石) and the Small Image’s “central and correct” (中正). The intent was admirable: to stand on one’s own like a rock while keeping to the centre. The Xici goes on to say that such a person neither flatters those above nor slights those below, knows the subtle and the manifest, the soft and the hard, and so becomes “the hope of ten thousand.” Without the Yijing, even the name cannot be read.
六三盱豫，悔。遲有悔。
In plain words
Gazing upward for delight brings regret; being slow brings regret.
Close reading
盱 is to look up with wide eyes, here at the face of the ruling fourth line just above. Yin in a yang place, out of position and unanswered by the top line, it can only look upward for favour. It too lies in the inner Gèn, but stops only when nearly at the stopping point, hence “slow.” The Small Image: “its position is not right.” Still, regret is better than humiliation: it means change remains possible.
If you drew this line
Do not buy comfort by watching someone else’s face, and do not linger when it is time to withdraw. The sooner you wake up, the less it costs.
九四由豫，大有得。勿疑。朋盍簪。
Variant Shown as 「朋盍簪」; some editions read 「戠」.
In plain words
Delight comes from here; great gains. Do not doubt: friends gather as hair is gathered by a clasp.
Close reading
由豫 is not “hesitation” but “delight arising from this”: the whole gua’s joy flows from the fourth line. Yang in a yin place, out of position, corresponding with the first line, and bound to all five yin lines. It sits within the inner Kǎn (lines three to five), which signifies worry and doubt, hence “do not doubt.” The character 戠 here is written 簪, a hairpin, in most received texts: one yang line gathers five loose yin lines as a pin gathers long hair. The Small Image: “its will is greatly carried out.”
One level deeper
Line 4, “the source of enthusiasm; much is gained; do not doubt; friends gather like hair in a clasp”: the fourth is a minister’s place, yet here it is the ruling line of the whole hexagram, and all five yin respond to it. It sits in the nuclear Kǎn of lines 3–5, which is doubt, so the text says “do not doubt”: deal with people in full sincerity, and friends gather like hair held by a pin.
If you drew this line
You are the one others rely on. Set doubt aside and draw people together in good faith; things will come about through you.
六五貞疾，恆不死。
In plain words
Persistent illness, yet long without dying.
Close reading
Yin in a yang place, out of position but central and on the throne, unanswered by the second line and riding on the ruling fourth. The ruler sits above while real power rests with a powerful minister below, so it is chronically uneasy; the inner Kǎn it lies in carries the image of heart-sickness. The Small Image spells it out: “persistent illness, because it rides the firm; not dying, because the centre is not lost.” Here 貞 means carrying on unchanged: softness settled into ease becomes an ailment, but the middle way keeps it alive.
One level deeper
Line 5, “chronically ill, yet it does not die”: Line 5 holds the throne but rides on Line 4, who has the real power: title and strength are split apart, like a long illness. It is also in the nuclear Kǎn, the troubled heart. But it is central, and the upper Zhèn stands for life springing back, so it is ill but does not die: an awkward position that can nonetheless endure.
If you drew this line
The title is yours, the leverage someone else’s, and a lingering unease is unavoidable. Keep to the middle and avoid extremes, and the situation will hold.
上六冥豫，成有渝，无咎。
In plain words
Delight in darkness; when it is complete there is a change; no blame.
Close reading
冥 is darkness: at the peak of delight it is easy to lose one’s head and refuse to wake. Yin in a yin place, correct, unanswered by the third line; it sits at the top of Zhèn, where the shaking from below is felt most, hence “change.” 成 is a piece of music reaching its close. The Small Image: “delight in darkness at the top: how could it last?” Precisely because the end has come, accepting change leaves it without blame.
If you drew this line
At the height of enjoyment it is time to turn. Be willing to change course and no harm follows.
Stories 典
Mencius looking displeased
As Mencius left the state of Qi, his disciple Chong Yu asked him on the road: “Master, you seem displeased, yet you taught us that the noble person neither resents heaven nor blames others.” Mencius answered, “That was one time; this is another.” Every five hundred years a true king should arise, he said, and the time was more than due; if heaven wished to bring order to the world, “in this age, who is there but me?” Why then should he be displeased? 不豫 means unhappy, and Mencius’s reply sets personal feeling inside the larger question of the times.
Born of hardship, dying of ease
Mencius lists men raised from obscurity: Shun from the fields, Fu Yue from building walls, Jiao Ge from selling fish and salt, Guan Zhong from prison, Sunshu Ao from the seashore, Baili Xi from the market. When heaven means to lay a great task on someone, he says, it first tries him with hardship, “to stir his mind, toughen his nature and add to what he cannot yet do.” His conclusion: “We live through sorrow and adversity, and die through ease and pleasure.” That is why Yù hides readiness inside delight: the real danger usually comes after success.
Insight 悟
Yù reminds us that the most dangerous moment is often the smoothest and happiest one. Every line that tries to draw pleasure from the ruler, the first, third and fifth, runs into trouble; only the second, which attaches to no one and keeps its own counsel, earns “steadfast, good fortune.” Joy itself is not the fault; indulgence is. When the time is ripe, move with it; in good times, cultivate virtue, stay grateful and act on the first signs. Readiness is not anxiety. It is staying clear-headed while glad.
