Introduction
Thunder moves with the wind: two things that keep going together. Duration pictures movement held over a long stretch.
In practice, this names a stretch where the answer is to keep going. Not dramatically, but for long enough to matter.
The judgement
“Duration has success. No blame. Perseverance furthers. It furthers one to have somewhere to go.”
In plain words: staying with it works, and persistence is what makes it work. The old text adds that having somewhere to go helps.
Read it as a direction held over time. Duration is not standing still; it is movement that keeps its line.
Core themes
- Endurance is the strength here. Intensity is not.
- A held direction needs somewhere to go, not just persistence.
- Repetition is what turns an effort into a form.
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, you want the long result immediately.
The old line says the danger persists, though the fault does not.
Impatience at the start tends to cost months, not days.
Line 2 九二
Here the line settles into the middle of the work and regret falls away.
Finding the right pace tends to end the second-guessing.
Line 3 九三
At this level the person cannot stay with anything, and shame follows.
The old line says the humiliation persists.
Inconsistency here costs more than a wrong choice would.
Line 4 九四
Here the effort continues but produces nothing, because it is in the wrong place.
The old image is a hunt in an empty field.
Persistence in the wrong ground tends to be rewarded with nothing.
Line 5 六五
At the centre, the holding is applied to character rather than to outcomes.
The old line finds this good for a receptive role and costly for a driving one.
Knowing which role you are in tends to decide whether this suits you.
Line 6 上六
At the top, movement never settles into a line.
The old line says this goes badly.
Rest is not the same as stopping, and neither is constant motion a direction.
Summary
Read as a whole, this figure asks you to hold a direction long enough to matter. Find the right pace, check the ground is worth the persistence, and keep the line.
