Line 4
九四 貞吉。悔亡。藩決不羸。壯于大輿之輹。
Nine in the fourth place means: Perseverance brings good fortune. Remorse disappears. The hedge opens; there is no entanglement. Power depends upon the axle of a big cart.
Line 6
上六 羝羊觸藩。不能退。不能遂。无攸利。艱則吉。
Six at the top means: A goat butts against a hedge. It cannot go backward, it cannot go forward. Nothing serves to further. If one notes the difficulty, this brings good fortune.

Yilin Verse
坐爭立訟，紛紛匈匈，卒成禍亂，災及家公。
Seated they quarrel, standing they litigate; in turmoil and uproar. At last it becomes catastrophe and rebellion; disaster reaches the head of the house.
— Jiao Yanshou, Yilin (Forest of Changes), 1st century BCE
Commentary
Thunder above heaven erupts into litigation and chaos. People sit down quarreling and stand up suing, the noise and confusion escalating without end, until the disorder crystallizes into genuine calamity that strikes the head of the household. The verse traces the familiar trajectory of petty disputes that metastasize into institutional collapse. From Great Power to Great Taming, heaven is stored within the mountain in Daxu — the image of accumulated wisdom restraining force. The transformation is cautionary: the mountain that should contain heaven's energy instead watches it leak through cracks of contention. When strength is squandered on internal strife rather than stored for purposeful action, even the patriarch cannot escape the consequences.
