Hexagram 43 is 夬 (guài), usually rendered Breakthrough or Displacement. It is built from the trigram Dui (兌 duì), Lake, sitting over Qian (乾 qián), Heaven. Five solid yang lines rise from below and press against a single yin line at the very top. The picture is a moment when strength has almost finished its work, and one last soft obstruction stands in the way of a clean resolution.
Read the shape plainly. Heaven, the creative and firm, is the base; the Lake, joyous and open, rests above. Water gathered in a high lake is water waiting to spill. In hexagram 43 the pressure has built to the point where it must break through, and the whole hexagram turns on how that release is carried out.
The two trigrams and what they picture
Qian below is pure yang: drive, clarity, the will to move forward. Dui above is a lake — moisture held up high, ready to overflow onto the ground. When the firm underpins the joyous in this way, the energy is upward and outward. The single broken line at the top is the last remnant of an old condition — a habit, a person, a compromise — that the rising strength is about to displace.
Because the yang lines are so many and the yin line so alone, the outcome is not really in doubt. What is in question is the manner. Overwhelming force can win the ground and still spoil the day. So hexagram 43 is less about whether the breakthrough happens and more about keeping it clean.

The counsel of hexagram 43 is that a resolution must be made openly, not by ambush. When something wrong or outworn has to be removed, the classic advice is to announce it truthfully at court — to name the matter in the light rather than settle it in a corner. Strength is on your side, but leaning on strength alone invites danger.
Two cautions sit inside the Judgment. First, do not reach for weapons or force as the first move; the situation is won by clarity and rallying support, not by a show of arms. Second, know your own base — be sure of where you stand and who stands with you before you press. The moment favours resolute action that stays honest about its own risk. A breakthrough carried by truth holds; one carried by aggression tends to rebound.
The Image and its lesson
The Image of hexagram 43 is the lake risen above heaven — water gathered so high it must come down. The natural lesson practitioners draw from it is generosity paired with restraint. The person of worth, seeing water about to pour, does not hoard it; wealth and benefit are let flow downward rather than dammed up. At the same time, one guards against resting on virtue as if the work were done.
The pattern is twofold: distribute what has accumulated, and stay alert while doing it. A dammed lake that bursts uncontrolled floods the fields below. The same energy, released with intention, waters them. Breakthrough is the release — the question the Image poses is whether you direct it or let it burst.
Practical guidance
In work, hexagram 43 tends to mark the point where a lingering problem finally has to be confronted — an underperforming arrangement, an unpaid debt, a decision long avoided. The tendency it favours is to act, but to act in the open: state the matter plainly, keep your records clean, and secure your allies before the confrontation rather than after. Winning by force here often costs more than the win is worth.
In relationships, this is the hexagram of the honest reckoning — the conversation that clears the air rather than the resentment that leaks out sideways. The counsel is to name the issue directly and without heat. The lone yin line is small; the temptation is to crush it, but contempt for the small thing is exactly where the danger hides.
On timing, read hexagram 43 as tendency, not verdict. It suggests a moment ripe for decisive release after a long build-up — favourable for finishing, less so for starting something raw. Move when your footing is sure and your intent is clear; the energy is already flowing your way, so the discipline is in how you channel it, not whether it moves.
Changing lines and where it tends
The active edge of hexagram 43 is that single yin line at the top, and the lines below describe stages of the approach — moving too soon, moving alone, holding firm under pressure, keeping resolve without cruelty. When lines change, the hexagram shifts toward a related situation. Displace that last yin line entirely and the figure becomes six yang lines, Hexagram 1, 乾 (qián), the Creative — pure strength, the ground fully cleared.
Its mirror is Hexagram 44, 姤 (gòu), Coming to Meet, where a single yin line returns at the bottom and something small quietly re-enters. Breakthrough removes; Coming to Meet is how the removed thing can steal back in. Reading them together is the reminder that a resolution has to be maintained, not just achieved.
