Trigram breakdown
Upper · Lake · 兌
Yang doubled below, yielding above. Joyfulness that overflows its banks.
Lower · Fire · 離
Yin held inside two yangs. Light that needs fuel; clarity that can dazzle.
Judgment
'Revolution' describes the moment when existing structures must be overturned because they have become incompatible with present reality. Fire burns beneath the lake - heat rises, water presses down, and the tension between these two forces makes the old arrangement unsustainable. This hexagram does not counsel gradual reform; it names the conditions under which a decisive break is not only justified but necessary. The offering here is genuine renewal, but only if the change is grounded in truth rather than impatience or grievance.
Image
Fire beneath a lake generates steam and disruption - two elements that cannot coexist without one transforming the other. This image teaches that revolution is not an act of will imposed from outside but a natural consequence of incompatible forces reaching a breaking point. The lesson is timing: the change must come when the tension itself demands it, not before resentment builds to recklessness and not after the moment has passed.
Essence
Character
This person sees what others avoid seeing: an arrangement that has stopped working and cannot be fixed from inside. They do not rush to that view. They study the structure slowly, because they have been wrong before. Once they are sure, they move fast and do not bargain. Their gift is clean timing and the nerve to end what is finished. The cost shows when breaking becomes a habit. Restlessness starts to pass for insight, and grievance passes for truth. Used a little differently, the same nature renews things. They break only what is truly spent, and they build something honest in its place.
With other people
Among others, this person is the one who says the thing is over. They are warm and easy to be near until the moment they decide, and then they will not move. People who need the old arrangement to stay pretend-real feel dropped, and some leave. When it goes right, a stuck group gets released. Others get a clear ending, a fair reason for it, and a place to start again.
Lake over Fire
Lake on the outside is a pleasant, open surface that invites trust, while Fire within burns toward a verdict, so the calm face hides a heat that is already deciding.
The six lines
Hexagram 49 Line 1 (49.1)
A yang line at the foundation carries genuine force, but revolutionary action taken before the situation has fully clarified leads to premature rupture. The energy is real; the moment is not yet ripe, and moving now risks acting on personal frustration rather than structural necessity.
Hexagram 49 Line 2 (49.2)
A yin line in the second earth position marks the point where conditions for change have genuinely matured - the tension is no longer personal but structural. Acting now, with clear purpose and legitimate standing, brings the transformation through cleanly.
Hexagram 49 Line 3 (49.3)
Three yang lines in succession create a concentration of force in the human position, and here the danger is pushing too hard too fast. Repeated calls for revolution that haven't yet gathered sufficient support will exhaust credibility; the right move is to consolidate rather than escalate.
Hexagram 49 Line 4 (49.4)
A strong yang line in the upper human position signals that the moment for action has arrived and the actor has sufficient standing to carry it through. Regret dissolves when the change is made with clarity and conviction rather than hesitation.
Hexagram 49 Line 5 (49.5)
The ruler's yang line at the peak of authority is the pivot of the entire hexagram - this is the figure who embodies the change rather than merely enacting it. When transformation proceeds from this position with genuine vision and moral weight, it succeeds completely and people align with it naturally.
Hexagram 49 Line 6 (49.6)
The top yin line represents revolution that has run its full course and must now settle. Attempting to extend the transformation further at this stage turns necessary change into destabilizing excess; consolidation and institutional grounding are what the moment now requires.

Gate 49 in Human Design
In Human Design, Hexagram 49, Revolution, is Gate 49, with the same six lines. It sits in the Solar Plexus Center, and its one channel connects it to Gate 19 in the Root Center. How to read your gates in the I Ching
The reading goes further down
What you have read here is the shape of Hexagram 49, 'Revolution'.
Underneath it sit four more: the mechanic that drives it, the shadows it casts, the way through them, and the tension between Lake and Fire that never quite settles.
And if this hexagram appeared in your Birth Hexagram Triad, one of its six lines is changing. That line is your growth edge, named out loud.
