I Ching hexagram 32
Hexagram 32: Heng
Endurance · 雷風恆 · Thunder above, Wind below
Staying power in any commitment comes from a steady direction and a willingness to keep adjusting.
What this hexagram is about
What makes a relationship or a habit last is the question here. Heng (Endurance) puts thunder above wind, two forces that stir each other and keep going, and the lines warn against demanding too much too soon and against changing course at every turn.
A way to think about it
Think about a commitment you want to keep. Which part of it needs to stay fixed, and which part needs to change so that the commitment can last?
The text, with Legge's translation
Judgment
亨，无咎。利貞，利有攸往。
Hăng indicates successful progress and no error (in what it denotes). But the advantage will come from being firm and correct; and movement in any direction whatever will be advantageous.
Lasting commitment keeps things open and draws no fault. It pays to stay correct, and the text adds that it is a good time to set out, since real endurance keeps moving.
Image
雷風，恒；君子以立不易方。
(The trigram representing) thunder and that for wind form Hăng. The superior man, in accordance with this, stands firm, and does not change his method (of operation).
Line 1 · 初六
浚恆，貞凶，无攸利。
The first line, divided, shows its subject deeply (desirous) of long continuance. Even with firm correctness there will be evil; there will be no advantage in any way.
You dig deep for a lasting bond before the foundations exist, asking for full commitment far too early. Even with good intentions, the text marks it a bad sign with no benefit.
Line 2 · 九二
悔亡。
The second line, undivided, shows all occasion for repentance disappearing.
Regret fades. The line says only that, and the tradition explains it by pointing to your hold on the middle ground, where you can last.
Line 3 · 九三
不恆其德，或承之羞，貞吝。
The third line, undivided, shows one who does not continuously maintain his virtue. There are those who will impute this to him as a disgrace. However firm he may be, there will be ground for regret.
You do not keep to your own standards from one day to the next, and sooner or later someone hands you the embarrassment for it. Staying stubborn about it only adds to the regret.
Line 4 · 九四
田无禽。
The fourth line, undivided, shows a field where there is no game.
You hunt for a long time in a field that holds no game. Persistence in the wrong place brings nothing home.
Line 5 · 六五
恆其德，貞，婦人吉，夫子凶。
The fifth line, divided, shows its subject continuously maintaining the virtue indicated by it. In a wife this will be fortunate; in a husband, evil.
Holding to one fixed way suits a person whose part is to follow. For the one who has to decide, rigid sameness is a bad sign, since each case needs its own judgment.
Line 6 · 上六
震恆，凶。
The topmost line, divided, shows its subject exciting himself to long continuance. There will be evil.
At the very top, where calm is needed, you stay in a constant state of agitation. The text marks restlessness as a habit here, and the reading is unfavorable.

Questions
I cast hexagram 32. Which text do I read?

But the advantage will come from being firm and correct; and movement in any direction whatever will be advantageous." With changing lines, read the lines that changed. When several change at once, Zhu Xi's rules decide which text leads, and the casting page marks it for you.
