卦旨
Dui is not pleasure. It is the joy that arises from genuine exchange between equals — the mutual enrichment that occurs when inner substance meets its complement and both are enlarged. Lake doubled upon itself (Dui above Dui) creates the image of two lakes connected, each replenishing the other. A single lake eventually stagnates or evaporates; connected lakes sustain. The judgment is characteristically spare: 亨,利貞 — "success, perseverance furthers." Joy without perseverance degenerates into indulgence; perseverance without joy becomes grim endurance. The line texts distinguish authentic joy from its counterfeits with surgical precision. The first line describes 和兌 — "harmonious joy" — which is fortunate because it arises from inner alignment, not external stimulation. The second line specifies 孚兌 — "sincere joy" — joy rooted in truthfulness, where remorse vanishes because nothing has been falsified. The third line warns against 來兌 — "coming joy" — pleasure that is sought or pursued rather than generated from within. The fifth line cautions against 孚于剝 — "confidence in what strips away," trust placed in forces that erode rather than build. The architecture is clear: joy that flows outward from inner truth is fortunate; joy that is imported, performed, or purchased is corrosive. The goal of Dui is communion — the kind of exchange that strengthens all participants without depleting any. The Image text names the mechanism: 君子以朋友講習 — "the superior person joins with friends in discussion and practice." Connected lakes are the image; mutual study is the method. Two people explaining what they know to each other learn more than either could alone. Dui teaches that genuine joy is not a reward for achievement but the natural condition of truthful exchange between people who bring substance to the encounter.
彖辞
Fulfillment. Sustained orientation is supported. Joy. Fulfillment. Sustained orientation supported. The judgment is simple because genuine joy is simple. Not complicated, not conditional, not dependent on circumstances. The joyous hexagram doesn't explain happiness. It just says: this is what it looks like when the configuration supports it. Sustained orientation — because joy without depth is just mood.
象辞
Joined lakes: the joyous. The realized person accordingly joins with friends for discussion and practice. Two lakes connected — each replenishing the other. And the instruction is: join with friends. Discuss. Practice. Because joy that isn't shared evaporates like a single lake. Joy that's connected — lake to lake, person to person — sustains itself. The realized person doesn't practice joy alone. That's not joy. That's an exercise.
爻辞
第初爻
Harmonious joy. Resolves well. Harmony. Joy. Resolves well. The simplest line in the joyous hexagram — joy that needs nothing, demands nothing, depends on nothing external. The first line: the joy that arises from inner harmony is the only kind that comes with a clean verdict. No conditions, no warnings. Just: this. This is the real thing.
第二爻
Sincere joy. Resolves well. Deviation detected dissolves. Joy rooted in sincerity. Resolves well. Whatever was off-course disappears. The second line: when joy comes from what's true rather than what's pleasant, it has the side effect of correcting everything around it. The deviation dissolves not because you addressed it directly. Because genuine joy is incompatible with falseness. They can't coexist.
第三爻
Approaching joy. Adverse. Joy coming from outside. Adverse. Two characters that diagnose an entire way of living: the person who waits for joy to arrive has confused happiness with delivery. The third line: joy that approaches you — that you don't generate internally — is the kind that takes more than it gives. The emptiness that attracted it is the emptiness it fills temporarily and deepens permanently.
第四爻
Deliberated joy is not yet at peace. Setting aside the urgency brings happiness. Weighing the options. Not at peace yet. But setting aside the anxious calculation: happiness. The fourth line describes the person who's deciding between pleasures and can't enjoy any of them. The fix isn't choosing better. It's stopping the deliberation. The person who sets down the comparison and just allows the joy to land has discovered that analysis and happiness operate on different circuits.
第五爻
Trusting in what disintegrates. There is danger. Placing your trust in the thing that's falling apart. Danger. The fifth line of the joyous hexagram, and the warning is specific: the source of your joy is decaying. You can see it. And you're trusting it anyway. Because the pleasure is still present even as the foundation is leaving. The person who clings to a disintegrating joy isn't optimistic. They're in danger.
第上爻
Led into joy. Led. Not leading, not choosing — led. Into joy. No verdict. The top of the joyous hexagram and the final image is someone who has given up direction entirely. The joy isn't chosen. It isn't resisted. It isn't evaluated. It's just... followed. The text leaves the verdict blank because at this point, what happens depends entirely on what's doing the leading. And the text can't tell you that.

麗澤兌,朋友講習之象。班馬還師,以息勞疲。後夫嘉喜,入戶見妻。班馬即歸師之戰馬。征人歸來,先息軍旅之勞,後入家門得見妻子,歡喜之至。從兌至兌,喜悅映照喜悅。麗澤之象——兩澤相連,互相滋潤。此為歡悅之純粹形態:離別後之重逢,門前見到熟悉之面容。兌之自返不是重複而是共鳴——如兩湖相映,喜悅加倍。
English commentary
Paired lakes mirror each other in perfect symmetry — The Joyous reflecting itself. The army's spotted horses return from campaign to rest their weary bones. Afterward, a husband comes home with joy, entering the door to see his wife. The phrase 'ban ma' (spotted horses) echoes the Shijing where returning warhorses signify the end of a campaign. From The Joyous to The Joyous, the transformation is identity: joy deepened by recognition. Friends lecture and practice together — the hexagram image made flesh. The soldier returns to domestic happiness; the doubled lake produces not excess but resonance. This is joy's purest form: reunion after absence, the familiar face at the threshold.
