Hexagram 54 of 64
Hexagram 54 of the 64, The Marrying Maiden, is thunder above, lake below — read as entering a situation from a weak position. Its six lines are 011001, counted from the bottom up, where a broken line is yielding and a solid one firm.
Upper trigram
Arousal and shock.
Lower trigram
Joy and openness.
From the Book of Changes itself
The Judgement
The marrying maiden. Undertakings bring misfortune. Nothing that would further.
The Image
Thunder over the lake. The superior person understands the transitory in the light of the eternity of the end.
These two texts are the hexagram. Everything else — the trigram analysis, the line positions, the modern keyword — is commentary built on top of them. The Judgement states the situation and its outlook; the Image draws the practical conclusion, and by convention begins with what the trigrams show in nature.
Rendered in plain English from the canonical text rather than copied from any one translation. If you want a specific scholarly version, Wilhelm-Baynes and Lynn are the two usually recommended.
Read from the bottom up. This figure runs yin yang yang yin yin yang — what each position means.
| Line | This hexagram | What the position means |
|---|---|---|
| 6 | ▬▬▬▬▬ yang | the situation past its peak — completion, or overreach |
| 5 | ▬▬ ▬▬ yin | the ruling position, usually the most favourable in the hexagram |
| 4 | ▬▬ ▬▬ yin | entering the outer sphere — proximity to authority, exposure |
| 3 | ▬▬▬▬▬ yang | the transition point, and the most dangerous position in the figure |
| 2 | ▬▬▬▬▬ yang | the inner sphere — home, private life, what you are among your own |
| 1 | ▬▬ ▬▬ yin | the beginning of the situation, still hidden and barely formed |
The lower trigram is the inner situation — Lake, joy and openness. This is what is happening in you, or in the private side of the matter.
The upper trigram is the outer situation — Thunder, arousal and shock. This is the world the inner position meets.
Metal below controls Wood above. The inner position restrains the outer, which reads as holding back circumstance rather than being carried by it.
Read as family, this is Eldest son above and Youngest daughter below. Two siblings, which reads as relationship between equals rather than hierarchy.
The eight trigrams are traditionally assigned family roles — Heaven is the father, Earth the mother, and the remaining six are three sons and three daughters. Which one sits above which is part of how a hexagram is read.
Calculated from the lines
Nuclear hexagram
Built from lines 2-3-4 and 3-4-5 of this figure — the hexagram hidden inside it. Read as what is happening beneath the surface of the situation.
Opposite hexagram
Every line flipped. The same situation turned inside out — useful for seeing what you are not currently considering.
Inverse hexagram
The same figure turned upside down — traditionally read as the situation seen from the other party's side.
None of these are assigned by an author — each follows from the arrangement of lines.
Thunder above, Lake below.
Thunder over Lake: arousal and shock meeting joy and openness.
That combination is the whole meaning of hexagram 54. Nothing about it is arbitrary — change either trigram and you get a different hexagram with a different reading, which is why the 64 form a system rather than a list.
