What the text says, in plain terms
The Judgement
Inner truth: sincerity that reaches even the most stubborn. Genuine trust makes great undertakings possible.
The Image
Wind over a lake, stirring the water to its depths. The lesson is to consider disputes carefully and temper severe judgments with understanding.
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
“Kung Fû (moves even) pigs and fish, and leads to good fortune. There will be advantage in crossing the great stream. There will be advantage in being firm and correct.”
“(The trigram representing the waters of) a marsh and that for wind above it form Kung Fû. The superior man, in accordance with this, deliberates about cases of litigation and delays (the infliction of) death.”
Act from real conviction, and approach others without prejudice. Understanding their position is what makes your influence work.
Deep trust and honest communication. Sincerity convinces where arguments fail.
Negotiations, leadership and conflict resolution that depend on credibility. Be exactly what you claim to be.
Read from the bottom up. This figure runs yang yang yin yin yang yang — what each position means.
4 yang and 2 yin lines. Three of the six stand in their proper place, and the pairs 1–4 and 3–6 answer.
Lake below — joy and openness — is the private, inner side of hexagram 61.
Wind above — gentle penetration — is the world that side meets.
Metal below controls Wood above. The inner position restrains the outer, which reads as holding back circumstance rather than being carried by it.
The eldest daughter sits above and the youngest daughter below. Two sisters, the older one on top — siblings rather than parent and child, so the order is one of seniority, not authority.
Calculated from the lines
Nuclear hexagram
What is happening beneath the surface.
Lines 2–4 give Zhen (Thunder) as the lower trigram, lines 3–5 give Gen (Mountain) as the upper.
Opposite hexagram
The situation turned inside out.
Change all six lines and Wind over Lake becomes Thunder over Mountain.
Inverse hexagram
Hexagram 61 reads the same upside down: Wind over Lake, turned over, is still Wind over Lake. Only eight of the sixty-four do.
None of these are assigned by an author — each follows from the arrangement of lines.
Wind above, Lake below.
Wind over Lake: gentle penetration meeting joy and openness.
