爻辞
第初爻
Return from not far. No need for remorse. Supreme good fortune. You haven't strayed far; the return is easy. Catching the error early enables the best outcome.
第二爻
Quiet return. Good fortune. Coming back in stillness and humility—this is the right way. No drama, just correction.
第三爻
Repeated return. Danger, but no blame. Returning again and again—you keep straying and correcting. The pattern is unstable, but the effort itself is not blameworthy.
第四爻
Walking in the middle, returning alone. You return to the right path while others continue wrongly. Solitary correction, no companions in the turn.
第五爻
Generous return. No remorse. Returning with nobility, magnanimously acknowledging the need to change. Nothing to regret in this.
第上爻
Confused return. Misfortune. Disaster and blunder. Using armies leads to great defeat in the end—the ruler's misfortune. Even after ten years, unable to attack. Lost on the way back, you make everything worse. The return that fails is catastrophic.

雷在地中,復之又復——本卦重疊於自身。周師伐紂,剋於牧野——周武王率師伐商紂,大勝於牧野。甲子平旦——甲子日拂曉。天下悅喜——四海歡騰。此為中國史上最典型之「復」:暴政終結,天命轉移,道德秩序重建。本卦自變,復歸加倍——所復者非一陽初動,乃整個文明之更新。牧野之勝即復卦之化身:義師歸正,暴虐所毀者一朝復原,恰合天道之黎明。
English commentary
Thunder returns beneath the earth and returns again — Return doubled upon itself. King Wu of Zhou leads his armies against the tyrant Zhou of Shang and triumphs at the Battle of Muye. On the jiazi dawn, under the first light, the world rejoices. This is the definitive return in Chinese history: the restoration of moral order after tyranny, the mandate of heaven transferring to the virtuous. The doubled hexagram intensifies the image — what returns is not merely a single yang line but an entire civilizational renewal. The Muye victory is return incarnate: righteous force restoring what cruelty had destroyed, timed to the cosmic daybreak.
