雷地豫 · Yù · Earth under Thunder
“Energy is rising. Point it at something, or it will scatter.”
Lower trigram ☷ Earth 坤 — receptivity & support
Upper trigram ☳ Thunder 震 — initiation & action
Trigram: a three-line symbolic figure that forms one half of an I Ching hexagram.
- Rising energy
- Shared momentum
- Timed action
- Clear signal
- Group movement
Introduction
Thunder rolls out over the earth: everything stirs at once. Enthusiasm pictures movement that carries others with it.
In practice, this names a stretch where energy and mood rise together. Momentum is available. Aim it, or it disperses.
The judgement
“Enthusiasm. It furthers one to install helpers and to set armies marching.”
In plain words: this is a moment for putting people in place and starting the movement. Shared energy wants an outlet.
Read it as a note about direction. Enthusiasm without a task turns into noise; with a task it moves a group.
Core themes
- Momentum is real here. It needs a task to be useful.
- Enthusiasm spreads. Choose carefully what you spread.
- Timing matters: moving with the mood costs less effort.
Line-by-line overview
Six lines, read bottom to top — matching the figure above.
Each line describes one stage in an evolving situation. Line 1 marks the earliest, foundational beginning; line 6 shows where the pattern has run its course. Open a line to read it.
Line 1 初六
At the base, energy shown off before it has a task invites difficulty.
Announced enthusiasm tends to burn before the work starts.
Line 2 六二
Here the line holds steady while everything else stirs.
Steadiness means deciding quickly, not waiting the whole day.
Perseverance in this posture carries good with it.
Line 3 六三
This line waits for someone else to supply the energy.
Remorse comes both from leaning upward and from hesitating.
Borrowed enthusiasm rarely lasts.
Line 4 九四
The strong line here gathers others without any doubt in it, and people follow the movement.
Friends gather the way hair gathers under a headdress.
Shared momentum usually starts with a single person who is clearly moving.
Line 5 六五
Near the top, something drags on without ending.
The old line describes a long illness that does not finish the person.
A lingering problem here is survivable. It is not the centre of things.
Line 6 上六
At the top, the mood has run past its usefulness.
The old line says that changing course after completion carries no fault at all.
Ending a stale enthusiasm is a clean act rather than a failure, and it leaves room for the next real thing.
Summary
Read as a whole, this figure describes rising energy that wants direction. Give it a task, gather the people, and step off the mood once it has passed.

- Ask whether the energy is yours or borrowed from the moment. Knowing the difference steadies you. Mixing them up tends to set up a letdown.
