Hexagram 26 of 64 · King Wen sequence
大畜 · dà chù
Mountain above heaven: great strength held and disciplined — power accumulated, restrained, and put to work.
Heaven inside the mountain: enormous strength contained, fed, and trained. Great Taming is Small Taming grown up — this is no longer restraining a horse with a hair, but building the barn that houses real power until it is useful.
The counsel has three registers: hold back what is not ripe, cross the great river when it is, and study the past hard enough that your strength has lineage. The discipline of great power is not restraint forever — it is restraint until the moment restraint would be waste.
