Duration
恆 · Héng

Success. No blame. Perseverance furthers. Furthers to have somewhere to go.
The Image
Thunder and wind: the image of Duration. Thus the superior man stands firm and does not change his direction.
What this hexagram is really saying
Héng is the hexagram of long-lasting things — marriages, careers, friendships, institutions, practices. The judgment is clean: "success, no blame, perseverance furthers." The question is what perseverance actually means.
Most people misunderstand duration as stillness. They think a lasting marriage is one where nothing changes; a lasting company is one that does the same thing for decades; a lasting practice is one that's rigid. The image of the hexagram corrects this. Thunder and wind, both moving constantly. Duration in the I Ching is not the absence of change — it is constancy of direction through change. The river keeps flowing toward the sea. The seasons keep cycling. The marriage keeps re-orienting toward shared values even as both people change.
The Wilhelm text adds an important note: "it furthers to have somewhere to go." Without direction, duration becomes inertia — staying in something because you've already stayed in it. Héng is not asking you to endure. It is asking you to recommit to direction.
The practical move: what is the actual long arc of this thing — the relationship, the work, the practice — that you've been treating as a noun rather than a verb? Re-find the direction. Adjust the form. Stay in motion. The things that last are the ones that keep evolving while pointing the same way.
