泽火革
去故取新，革而当之
The Judgment
Revolution: on the appointed day you win trust. Sublime success comes to those who persevere in what is right, and regret fades away.
This sign stands for casting off the old order and bringing forth the new. Only when the moment has fully ripened does change carry conviction; then it flows freely, and holding to a righteous course dissolves all cause for remorse.
泽中有火，革。君子以治历明时。
革，水火相息，二女同居，其志不相得，曰革。巳日乃孚，革而信也。文明以说，大亨以正，革而当，其悔乃亡。天地革而四时成，汤武革命，顺乎天而应乎人，革之时大矣哉！
Interpretation(original text)
革者，变革也，去故取新之义。《说文》云「兽皮治去其毛」，引申为除旧布新、变革更化。革卦上兑（泽）下离（火），水火相息，二女同居而志不相得，故有变革之象。程颐谓「天地革而四时成」，革非轻率之举，乃势之所趋、理之所当。
上兑为泽水，下离为火，火燃于泽下，水火交战，既有冲突亦有更化之机。泽中有火，蒸腾变化，旧质消融而新态生成。王弼注「水火相息，各得其用」，虞翻以互体论之，内含乾健巽入之象，变革之中兼具刚健与渐进。
九五为卦主，阳刚中正居尊位，大人虎变，文炳彪著。六二柔顺中正与九五正应，可辅成革命之功。初九居下位以「巩用黄牛之革」戒其轻动，上六「小人革面」则示革之终须安定人心。全卦阴阳交错，刚柔并济，体现变革需审时度势。
革为第四十九卦，与鼎（第五十卦）相综。《序卦》曰「井道不可不革，故受之以革」。革与鼎为一对，革为破旧，鼎为立新，朱熹谓「革去故而鼎取新」，二者相辅相成，缺一不可。
The Lines
He is bound fast with the hide of a yellow ox.
The time is not yet ripe. Hold your ground firmly, self-possessed, and make no rash move.
Image: 巩用黄牛，不可以有为也。
初九以阳居初位，革之始也，力量尚弱，时机未至。故曰「巩用黄牛之革」，以黄牛之皮坚固束缚自身，戒其轻举妄动。程颐注「当革之初，事未可也」，需坚守中道、静待时变。
When the appointed day arrives, then carry out the change. To advance brings good fortune and no blame.
Wait until the moment has fully matured before enacting reform; only then is moving forward auspicious and free of fault.
Image: 巳日革之，行有嘉也。
六二以柔居中，得正且与九五正应，革之时机已至。「巳日乃革之」，待时而动则吉无咎。朱熹谓此爻「柔顺中正，应乎刚」，既有变革之志又具审慎之德，故能征吉。
To press forward brings misfortune, and even steadfastness holds danger. Only when talk of change has gone round three times does trust take hold.
Acting rashly invites peril, and even standing firm demands caution; a reform wins confidence only after its case has been weighed again and again.
Image: 革言三就，又何之矣。
九三阳刚居下卦之极，革言三就，再三审议乃可信从。处离火之上、兑泽之下，正当水火交争之际。王弼注「处下体之极，居上体之下」，革之关键在于征而后行、慎之又慎。
Regret fades. Carried by sincerity, he changes the old mandate. Good fortune.
Doubt is dispelled; reform driven by genuine good faith overturns the old order and brings fortune.
Image: 改命之吉，信志也。
九四以阳居柔位，虽不当位却近乎君位，能改命则吉。此爻处上下卦交接之际，承上启下，变革最为剧烈。程颐谓「改命之吉，信志也」，需以至诚感人、以信义取信于众。
The great man transforms as a tiger renews its stripes. Before ever consulting the oracle, he is trusted.
A great leader renews the world as vividly as a tiger's markings; his sincerity wins the people without need of proof.
Image: 大人虎变，其文炳也。
九五阳刚中正居尊位，为革卦之主。「大人虎变」，威德昭著，如虎之文采斐然，未占有孚。朱熹注「虎变谓文炳然」，此乃变革大成之时，天下瞻仰、人心归附。
The noble one transforms like a panther; the small man merely refashions his face. To march further brings misfortune, but to abide in what is right brings good fortune.
The worthy person renews himself to the core while lesser folk only outwardly comply. Pressing on now is dangerous, but resting in correctness is auspicious.
Image: 君子豹变，其文蔚也；小人革面，顺以从君也。
上六居革之终，柔顺处极。大人已虎变，君子已豹变，小人则革面以从之。此爻示变革尾声当以安定为务，虞翻谓「居则贞吉」，不宜再有征伐之举，守成方为正道。
