Hexagram 62 of the 64, Small Exceeding, is thunder above, mountain below — read as attend to small things, not large ones. Its six lines are 100001, counted from the bottom up, where a broken line is yielding and a solid one firm.

The Judgement and the Image
The Judgement
Preponderance of the small. Success. Perseverance furthers. Small things may be done; great things should not be done.
The Image
Thunder on the mountain. The superior person gives preponderance to reverence in conduct.
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 yang yin yin 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 | ▬▬ ▬▬ yin | the transition point, and the most dangerous position in the figure |
| 2 | ▬▬ ▬▬ yin | the inner sphere — home, private life, what you are among your own |
| 1 | ▬▬▬▬▬ yang | 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 — Mountain, stillness and limit. 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.
The five-element relation
Wood above controls Earth below. Circumstance restrains the inner position — pressure comes from the situation, not from within.
Read as a family
Read as family, this is Eldest son above and Youngest son 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.

2 · The Receptive
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
61 · Inner Truth
Every line flipped. The same situation turned inside out — useful for seeing what you are not currently considering.
Inverse hexagram
Symmetrical
This hexagram reads the same upside down. Only eight of the sixty-four do — a small, distinctive group.
None of these are assigned by an author — each follows from the arrangement of lines.
The image
Thunder above, Mountain below.
Thunder over Mountain: arousal and shock meeting stillness and limit.
That combination is the whole meaning of hexagram 62. 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.
