地水师Shī · Multitude
坤上 · 坎下Earth over Water
卦辞The Judgement
师：贞，丈人吉，无咎。Shī. Be steadfast and upright. A venerable leader brings good fortune. No fault.
需要带领一群人或一个团队完成有挑战的目标。下坎为水，居北方，是潜伏的险、内在的忧患；上坤为土，居西南，是广大民众、承载之力。坤土克坎水——大地把暗流险川收容在内，化险为力，这就是师卦的精髓。最关键的是有威望的领导者、严明的纪律、正当的目标——三者缺一不可。师出无名或纪律松散，必败。
You're called on to lead a group, or take a team through a real challenge. The lower trigram Kǎn is Water, in the north — the hidden danger, the inner trouble; the upper trigram Kūn is Earth, in the southwest — the broad masses, the bearing strength. Kūn's Earth checks Kǎn's Water: the great land takes the dark currents into itself and turns danger into force, and this is the heart of the Army hexagram. Three things matter most: a respected leader, strict discipline, and a just cause — miss any one, and you fail. An army without legitimate purpose, or without discipline, always loses.
大象The Image
《象》曰：地中有水，师；君子以容民畜众。Water gathers within the earth: the image of the Army. The noble one, accordingly, embraces the people and gathers a following.
六爻The Six Lines
初六，师出以律，否臧凶。The army sets out with discipline. Otherwise, misfortune.
做事一开始就要立规矩、定章法。坎水初爻，水刚从源头出——此时不筑堤，后面就是洪水。基础没打好就行动，再正确的方向也会乱套。前期辛苦的纪律建设，是后期一切顺利的根本。
Set the rules first, get the order in place first — and only then act. Kǎn's Water, first line, just leaving the source — fail to build the dyke now and a flood follows. Move without a foundation, and even the right direction collapses into chaos. The hard discipline-work at the beginning is the root of everything going smoothly later.
九二，在师，中吉，无咎；王三锡命。In the midst of the army. Good fortune. No fault. The king bestows commands three times.
如果你处在带队/管理位置上，九二阳爻居坎中——是水里的定海神针，也是全卦唯一的阳刚核心，会得到上级的信任和重托。把握好这种信任——既不能辜负，也不能仗着信任就为所欲为。
If you hold a leading position, the second line, yang, in the middle of Kǎn — the steadying anchor in the water, the one firm core of the whole hexagram, you'll receive the trust and weight of those above you. Carry that trust well — don't betray it, but also don't let it go to your head and overreach.
六三，师或舆尸，凶。The army perhaps carries corpses in carts. Misfortune.
队伍出现严重问题（人心散了、目标偏了、有人擅自行动），损失惨重。六三阴爻失位，坎水泛滥——水没被土制住，开始反噬。这时不要硬撑——承认问题、立刻整顿，才能挽回局面。
The team is breaking down — morale gone, direction lost, people acting on their own initiative — and the losses are real. The third line, yin, out of place, Kǎn's water overflowing — the water is no longer held by earth and begins to turn back on itself. This isn't a moment to brazen it out. Admit the problem, restructure now, and you may still recover.
六四，师左次，无咎。The army retreats and camps. No fault.
暂时撤退、保存实力，不是失败而是策略。六四阴爻居坤卦初位——土开始发挥作用，用厚重包容的姿态先退一步。看起来在退让，其实在等更好的反击时机。别人怎么说不重要，关键是保住底牌。
Pulling back to conserve strength isn't defeat — it's strategy. The fourth line, yin, at the base of Kūn — earth begins to do its work, taking one step back with a heavy, all-holding poise. What looks like backing down is actually positioning for a better counterattack. Don't worry about how it looks; worry about keeping your hand.
六五，田有禽，利执言，无咎；长子帅师，弟子舆尸，贞凶。There are game in the fields. Favorable to seize them with cause. No fault. Let the senior lead the army. If the juniors lead, they will bring corpses back. Steadfastness: against misfortune.
出师必须有正当理由——坤土居中，土德宽厚，不是主动出击者，而是被侵犯后才反击，别人欺负到家门口，你才出击。但行动后要守住底线：不要让能力不强或心术不正的人带队，否则会反受其乱。
Only fight when there is real cause — Kūn's Earth centered, its virtue broad and generous — not the one who strikes first, but the one who strikes back only after being wronged — when the trouble has come to your door. But once you act, hold a strict line: don't put incompetent or unreliable people in charge of the operation, or they'll bring you greater trouble in return.
上六，大君有命，开国承家，小人勿用。The great prince issues commands: open states, sustain houses. Inferior persons are not to be employed.
事情结束、要论功行赏时，上六阴爻居坤之极——厚土收官，成败在此一判，区分清楚谁该重用、谁该奖励但不重用。能干但不正派的人，可以给好处，但不能给位置——否则会埋下更大的祸根。
When things wrap up and rewards are handed out, the top line, yin, at the extreme of Kūn — the thick earth closes the books, and success or failure is judged right here — draw a clear line between those who should be promoted and those who should only be paid off. Capable but unprincipled people can be given material reward, but never put in positions of authority — or you plant seeds for bigger trouble later.
