Game in the Field, and the Right Commander

The fifth line occupies the ruling position of the hexagram, and its counsel returns directly to the question of authority the whole hexagram is built around. When game enters the field it is right to catch it, the line says, framing the campaign as a justified response to a real provocation rather than an unprovoked action, but it adds a pointed condition: command should rest with the elder, capable son rather than be shared with the inexperienced, or disorder follows even a just cause. This is a striking admission for the line occupying the ruler's own seat, that rightness of cause is not sufficient on its own, and that the ruler's proper role here is to recognize and defer to genuine capability rather than to exercise command personally or divide it among the untested.

Read together with line two, the sole firm line in the hexagram, this line effectively names where real authority belongs, the capable commander rather than the ruling position itself, and warns that even a fully justified campaign can still end in disorder if that authority is not concentrated correctly. The line's honesty about its own limitation is unusual within the sequence generally, where the ruling position is more often praised without qualification, and it marks Hexagram 7 as particularly concerned with the difference between holding authority and being fit to exercise it.
