Hexagram 42: Increase Changing to Hexagram 16: Enthusiasm

I Ching casting meaning · Yi → Yu

Increase's steady growth is catching a rhythm — Enthusiasm, where private expansion becomes shared electricity. Your growth isn't just a spreadsheet anymore; it's contagious. People feel the momentum and want in: investors, partners, team members, an audience. Your job shifts from grower to conductor — give the excitement structure before it dissipates into expansion euphoria without a plan. Announce the vision, set the date, assign the parts. One warning: don't get so high on your own growth story that you miss the numbers. Directed enthusiasm builds movements; undirected enthusiasm just throws a very exciting party that leaves everyone hungover and the growth curve flat.

A casting that moves from Increase into Enthusiasm 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, 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 Enthusiasm.

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 16, Enthusiasm

Collective energy ignites. Ride it, direct it, don't drown in it.

The changed hexagram is the trajectory, not a verdict. As the moving lines settle, the energy of Increase gives way to Enthusiasm (Yu) — Earth below Thunder. The advice that belongs to this outcome: Catch the wave, then give it structure before the energy dissipates.
