The Army

The first six is a yin line in a yang position at the very bottom of Shi—the starting point of the army's campaign. 'An army must set forth in proper order; if the order is not good, misfortune threatens' establishes the first principle of warfare from the outset: discipline. 'Order' (lu) refers both to military regulations and to rhythm and structure. An army must march with strict discipline; otherwise ('not good') misfortune follows. 'Not good' carries two layers of meaning: poor discipline and inability to distinguish good from evil. An army with lax discipline and unclear rewards and punishments is vulnerable no matter how large its numbers. The wisdom of this line applies to all organizational management: whether a company, team, or project, the most important thing at the outset is establishing rules and systems. Without rules, nothing takes shape.

The second nine is the only yang line in Shi, centered in the lower trigram—strong and balanced, the commander of the entire army. 'In the midst of the army; good fortune, no blame; the king bestows a triple decoration' portrays the ideal military leader: present among the troops ('in the midst'), sharing hardships with soldiers; achieving good fortune without fault ('good fortune, no blame'), commanding skillfully; and receiving triple royal commendation ('the king bestows'), with distinguished merit. As the sole yang line surrounded by five yin lines, the second nine symbolizes an outstanding general leading many soldiers. His ability to command respect comes not from wielding power but from leading by example and maintaining upright character. This is the concrete embodiment of 'a strong man brings good fortune'—true leadership comes from the combination of virtue and ability.

The third six is a yin line in a yang position—neither centered nor correct, the most perilous line in Shi. 'Perchance the army carries corpses in the wagon; misfortune' presents a devastating image—the army returning with wagons full of dead, the aftermath of defeat. The third six is dangerous because a weak, unqualified person occupies a position they should not hold; lacking ability yet commanding the army inevitably leads to failure. 'Carrying corpses' represents not only military defeat but leadership failure—the wrong person in the wrong position making wrong decisions. The warning of this line is profoundly important: improper appointment is the root cause of all organizational failure. In modern enterprises, placing unsuitable people in key positions produces equally catastrophic consequences.

The fourth six is a yin line in a yin position—gentle and correctly placed, making a wise choice. 'The army retreats; no blame' means the army withdraws to the left and makes camp, without fault. 'Retreating to the left' signifies withdrawal and encampment—a strategic retreat in military terms. The fourth six, being yin in nature, understands it lacks the strength for direct confrontation and chooses to fall back—this is not cowardice but the wisdom of reading the situation. In military strategy, 'fight when you can, defend when you cannot fight, retreat when you cannot defend' is a fundamental principle. The fourth six's retreat preserves the army's fighting strength and creates conditions for future counterattack. In modern business, this is equivalent to contracting operations and conserving strength when market conditions are unfavorable.

The fifth six is a yin line in a yang position—softness in the place of honor, the sovereign's position in Shi. 'There is game in the field; it furthers one to catch it; no blame' means there is legitimate prey to be captured—justified defense is reasonable. 'Let the eldest lead the army; the younger transports corpses; perseverance brings misfortune' states Shi's most important principle of personnel: the experienced 'eldest son' must command the army; if the young and immature 'younger son' is put in charge, the result is 'transporting corpses'—returning with the dead. As the sovereign, the fifth six's most important duty is not personally entering battle but selecting the right commander. The wisdom of this line is that a leader's greatest ability is recognizing and employing talent. Choose the right person and efforts are doubled; choose the wrong person and everything is lost.

The top six is a yin line in a yin position at the very peak of Shi—the war has ended and the phase of rewarding merit has begun. 'The great prince issues commands, founds states, vests families with fiefs; inferior people should not be employed' is the supreme principle of post-war governance. 'The great prince issues commands' refers to the sovereign promulgating decrees; 'founding states and vesting families' means enfeoffing meritorious officials and establishing noble houses. But the most critical words are the final four: 'inferior people should not be employed'—petty, unprincipled people must absolutely not participate in the post-war distribution of power. The wisdom of this line is that winning the realm is difficult, but keeping it is harder still. If rewards are unjust and petty people are appointed after victory, the seeds of future disaster are planted. The decline of countless dynasties throughout history began with petty people gaining power.
