大過 → 坎

Commentary

Lake over wind plunges into doubled water — the Abysmal, danger upon danger. Sitting they quarrel, standing they litigate, in frantic confusion. The turmoil culminates in rebellion and disaster that reaches the lord of the house. The verse traces an escalation from petty bickering to full catastrophe: disputes that begin as seated arguments rise into standing confrontations, then spiral into chaos that destroys the patriarch himself. From Great Exceeding to the Abysmal, the sagging beam collapses into the pit. Water upon water offers no foothold — the quarreling parties have entered a recursive trap where each conflict generates the next. The 'family lord' who suffers the final blow is the center that failed to hold when the structure gave way.
