Hexagram 42: Increase Changing to Hexagram 43: Breakthrough

I Ching casting meaning · Yi → Guai

Increase is pushing toward Breakthrough — five strong lines against one remaining barrier, and the expansion is almost fully unlocked. The last obstacle — a competitor, a regulation, a limiting belief, a key hire who hasn't signed — is ready to fall. Handle the final push openly: declare what you're breaking through, rally your expanded resources, and don't brawl with the last barrier on its terms. Transparency wins; grappling in the mud with the final obstacle just stains the victory. The breakthrough that completes an increase arc isn't dramatic — it's the quiet, final removal of the thing everyone knew was in the way. Clear it. The path beyond is wider than anything before.

A casting that moves from Increase into Breakthrough means the situation you asked about is not static — it begins as one pattern and resolves into another. The first hexagram describes where you stand; the second describes where events are carrying you.

Highlighted in red: lines 2, 3, 4 and 6 are moving — counted from the bottom. A moving line is where the change is actually happening: it flips from yang to yin or back, and that flip is what turns Increase into Breakthrough.

The situation: Hexagram 42, Increase

True increase. Wind and thunder multiply each other.

Wind and thunder feeding each other — energy that multiplies instead of canceling out. This is one of the great draws: genuine increase, the kind where resources, opportunities, and momentum all rise together. The classic instruction has a spine to it, though: increase flows to people who use it well. See good, copy it fast. See your own faults, cut them faster. This is also the season to do something significant with the surplus — invest in people, take the meaningful risk, fund the thing that matters. Increase hoarded curdles; increase circulated compounds. You're being given more because the universe expects you to move it.

Structurally, Increase is Thunder below Wind — the inner state meeting the outer condition. That pairing is the lens for everything above.

Where it's heading: Hexagram 43, Breakthrough

One holdout left. Break through openly, without violence.

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Increase gives way to Breakthrough (Guai) — Heaven below Lake. The advice that belongs to this outcome: Break through in the open: declare the truth, rally allies, skip the brawl.
