What the text says, in plain terms
The Judgement
Duration: staying the course. Lasting success comes from consistency that still renews itself, not from rigid sameness.
The Image
Thunder and wind, always paired. The lesson is to stand firm in your direction without becoming inflexible.
A summary of meaning written for this site, not a translation — James Legge’s 1882 translation of the full text follows below. How the Judgement and the Image are read, and which translations to use →
Primary source
“Hăng indicates successful progress and no error (in what it denotes). But the advantage will come from being firm and correct; and movement in any direction whatever will be advantageous.”
“(The trigram representing) thunder and that for wind form Hăng. The superior man, in accordance with this, stands firm, and does not change his method (of operation).”
Choose the option you can keep up over time. Commit, and keep adjusting the details while the direction stays fixed.
Long-term commitment and marriage. Endurance works when routines are kept alive rather than simply repeated.
Long projects, careers and institutions. Persistence and gradual improvement beat sudden reinventions.
Read from the bottom up. This figure runs yin yang yang yang yin yin — what each position means.
3 yang and 3 yin lines. Two of the six stand in their proper place, and all three pairs answer each other.
Wind below — gentle penetration — is the private, inner side of hexagram 32.
Thunder above — arousal and shock — is the world that side meets.
Both trigrams are Wood, so nothing in the figure pulls against anything else. That makes the reading unusually single-minded — and unusually short of internal correction.
The eldest son sits above and the eldest daughter below. A brother and a sister of the same rank in age, which reads as a relationship between equals.
Calculated from the lines
Nuclear hexagram
What is happening beneath the surface.
Lines 2–4 give Qian (Heaven) as the lower trigram, lines 3–5 give Dui (Lake) as the upper.
Opposite hexagram
The situation turned inside out.
Change all six lines and Thunder over Wind becomes Wind over Thunder.
Inverse hexagram
The situation seen from the other side.
Turn the figure upside down and Thunder over Wind becomes Lake over Mountain.
None of these are assigned by an author — each follows from the arrangement of lines.
Thunder above, Wind below.
Thunder over Wind: arousal and shock meeting gentle penetration.
