I Ching trigram
Thunder
Thunder (☳, Zhèn) is one of the eight trigrams of the I Ching — the natural forces the 64 hexagrams are built from. Its essence: shock · movement · arousing. Thunder appears in 16 positions within the 64 hexagrams: as the upper trigram in eight and as the lower trigram in eight, and carries itself twice in hexagram 51 (Shock).

Thunder as the upper trigram
The eight hexagrams with Thunder on top.
- 16. EnthusiasmWhen energy gathers around a rhythm, movement becomes contagious.
- 32. EnduranceEndurance lives not on hardness, but on a rhythm that can keep carrying itself.
- 34. Great PowerGreat power is only great when it holds more measure than urge.
- 40. ReleaseRelease comes here not from force, but from the loosening of what has held on too long.
- 51. ShockShock breaks the taken-for-granted open and asks what still stands upright after.
- 54. Marrying InWhoever enters without a central place must know all the more sharply what is, and is not, their dignity.
- 55. AbundanceAbundance lights much at once, and for that very reason one must not go blind on its fullness.
- 62. Small ExcessWhen the small holds sway here, the way is not the grand gesture but the right fineness.
Thunder as the lower trigram

- 17. FollowingTo follow without testing is to wear another's direction as your own fate.
- 21. Biting ThroughWhat is stuck in the passage asks not for discussion, but for one clean bite.
- 24. ReturnAfter the far edge of distance, something small and true turns back.
- 25. InnocenceWhere movement is not spoiled by calculation, the true gains room of its own accord.
- 27. NourishmentWhat you feed shapes you; what you take in later speaks back out of your own mouth.
- 42. IncreaseIncrease is favorable only when what grows truly feeds the right direction.
- 51. ShockShock breaks the taken-for-granted open and asks what still stands upright after.
