The great image says: Repeated thunder: shocks. The noble one through anxiousness and fear sets in order and examines.
Zhèn: the ideogram and the story (NEW). What does it mean for your question?
This hexagram is complementary to hex.57.
Top 6: The shock is twining, twining, looking around in terror, terror. To set things right: pitfall. The shock does not reach oneself; it reaches one's neighbor, no fault. A marriage brings talk.
Many shocks are not really yours. Don’t try to mend them, even though they can be upsetting. They are valuable lessons. Connect with others and talk about it. Understanding and learning from it are better than fixing it.

4: The shock releases the mud.
The soul can only shine when the dirt is removed. As long as it is not clear, life harbors cliché’s, habits. Without a shock now and then the spirit gets lazy and the soul gets clogged. But - it might be a shock which causes a mudslide, and it just might hit you. So be very careful about shocks in the making, and avoid the wrong ones.

6 at 3: The shock: reviving, reviving. The shock moves without mistake.
Shocks inspire to greater deeds than normal thinking can imagine. Use them, don’t let them fade away, don’t let anyone talk you back to normal size. Great and often dreadful happenings, with the courage they ask, give power and depth to life.

6 at 2: The shock comes, danger. A hundred thousand lost coins. Climb the nine mounds, do not pursue, the seventh day you will acquire them.
Do not fear loss, do not chase after things. You have what belongs to you, and if you lose it, it will return again. Fears are apt to chase things rather than to hold them. Stop searching down there for coins, look upwards to higher things and get the courage and perseverance to tackle them.

Initial 9: The shock comes: fright fright. After that laughter and talk: shriek shriek. Auspicious.
Thoughtlessness is one of the biggest causes of trouble. Not stupidity, not inexperience, not taking too much risk. Just think of all the things you would have done different if you had thought before acting. So be grateful for shocks, they hit you out of thoughtlessness. Many have been saved from disaster by a shock, or even from death. And once your mind is awake again, look back and realize the waste of a life with a sleeping mind.

No lines changing: you can try to do things, but they may fail or even backfire. If there's nothing that should (or can) be done, then this might be a good time to relax and refuel. The Poem and the Image are guides that show you the best way to do that.
The Trigrams offer possibilities that the hexagram-texts don't show.
