Hexagram 42: Increase Changing to Hexagram 32: Duration

I Ching casting meaning · Yi → Heng

Increase's dramatic growth is finding Duration — the expansion happened, and now the question is whether the larger scale can last. Endurance isn't growth; it's the boring months after the growth spurt where you maintain the new size day after day. Keep the commitment to the expanded operation, update the methods of running it. The failure modes are chasing another growth hit out of boredom and letting the new size decay through neglect. Steady motion at the new scale — maintaining, optimizing, deepening — is what permanent increase is actually made of. Growth that endures is growth that knows when to stop growing and start inhabiting. Duration is the boring, essential partner of every expansion.

A casting that moves from Increase into Duration 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 1, 2, 3, 4, 5 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 Duration.

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 32, Duration

What endures is what renews. Hold the course, refresh the method.

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Increase gives way to Duration (Heng) — Wind below Thunder. The advice that belongs to this outcome: Keep the commitment, update the method. Endurance is motion, not stillness.
