Hexagram 42: Increase Changing to Hexagram 17: Following

I Ching casting meaning · Yi → Sui

Increase, successful in its own expansion, is moving into Following — the instruction is to attach your growth energy to something already in motion rather than always originating. You've proven you can grow; now prove you can draft. Somewhere nearby a current is moving — a trend, a leader, a wave — and the smart play is joining it with your expanded resources rather than competing against it. Choose what you follow based on values and direction, not novelty or flattery, because following makes you complicit in whatever you attach to. Once you choose, commit your increased capacity fully. Increase that knows when to follow channels its growth into a force multiplier. Increase that always leads eventually leads alone.

A casting that moves from Increase into Following 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 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 Following.

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 17, Following

Smart following. Attach to what's actually moving.

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Increase gives way to Following (Sui) — Thunder below Lake. The advice that belongs to this outcome: Follow the strongest current this week — but keep your standards and exits.
