Commentary

Thunder above wind, Duration's fixed course, gives way to earth above lake — Approach's expanding authority. The spirit resides in the chou position; reversals and obstructions bring blame. The southwest direction is unfavorable; people halt and linger behind. The verse invokes calendrical and directional calculations typical of Han-era divination practice. The spirit's position in chou (the ox hour, northeast) clashes with movement toward the southwest, creating a fundamental disharmony between cosmic timing and intended direction. From Duration to Approach, the steady rhythm should lead to expanding influence, as the lake's surface rises toward the earth above. But when the traveler moves against the prevailing spiritual current, persistence becomes transgression and approach meets resistance.
