The Judgement and the Image
The Judgement
Treading upon the tail of the tiger. It does not bite. Success.
The Image
Heaven above, the lake below. The superior person discriminates between high and low, and gives the people a secure footing.
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.
The six lines
Read from the bottom up. This figure runs yin yang yang yang yang yang — what each position means.
| Line | This hexagram | What the position means |
|---|---|---|
| 6 | ▬▬▬▬▬ yang | the situation past its peak — completion, or overreach |
| 5 | ▬▬▬▬▬ yang | the ruling position, usually the most favourable in the hexagram |
| 4 | ▬▬▬▬▬ yang | 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 |
What the two trigrams do to each other
Inner and outer
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 — Heaven, creative force. This is the world the inner position meets.
The five-element relation
Both trigrams are Metal, so nothing in the figure pulls against anything else. That makes the reading unusually single-minded — and unusually short of internal correction.
Read as a family
Read as family, this is Father above and Youngest daughter below. A parent over a child, which the tradition reads as guidance, authority or constraint depending on the rest of the figure.
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.

Nuclear hexagram
1 · The Creative
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
15 · Modesty
Every line flipped. The same situation turned inside out — useful for seeing what you are not currently considering.
Inverse hexagram
9 · Small Taming
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.
The image
Heaven above, Lake below.
Heaven over Lake: creative force meeting joy and openness.
That combination is the whole meaning of hexagram 10. 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.
