重險·在險中行險
先看圖像，再讀文字。Read the image before the words.
水洊至，習坎
(The representation of) water flowing on continuously forms the repeated Kan.
君子以常德行，習教事。
The superior man, in accordance with this, maintains constantly the virtue (of his heart) and (the integrity of) his conduct, and practises the business of instruction.
水一重一重地流來，是習坎之象。君子仿此，以恆常的德行為操守，反覆練習教化之事。 （水反覆流過同一處才能沖出河道；在重險中反覆練習，才能走出道路。）
(The representation of) water flowing on continuously forms the repeated Kan. The superior man, in accordance with this, maintains constantly the virtue (of his heart) and (the integrity of) his conduct, and practises the business of instruction.
先讀經文，再讀《彖傳》如何解釋卦辭。The received text, then the Tuan commentary on it.
習坎：有孚，維心亨，行有尚。
習坎，身處重重之險仍懷誠信，唯內心通達，行動才受嘉尚。 外在條件都不可恃，能倚靠的只有內心；心通了才能行動，行動才有功。
Kan, here repeated, shows the possession of sincerity, through which the mind is penetrating. Action (in accordance with this) will be of high value.
習坎，重險也。水流而不盈，行險而不失其信。「維心亨」，乃以剛中也。「行有尚」，往有功也。天險，不可升也；地險，山川丘陵也。王公設險以守其國。險之時用大矣哉！
習坎，重重之險。水流而不盈滿，在險中行進而不失信。「維心亨」，是因剛居中位。「行有尚」，是前往而有功。天之險不可攀升，地之險是山、川、丘、陵。王公設險，如建城牆、築工事，以此守國。險的用處，何其大啊！
Kan, here repeated, shows two defiles, (one above the other). In such a double defile water will flow on, without accumulating its volume (so as to overflow); one may pursue his (dangerous) course without losing his sincerity. 'That the mind is penetrating' is indicated by the strong (line) in the centre. That 'action (in accordance with this) will be of high value' tells us that advance will be followed by achievement. The dangerous (height) of heaven cannot be ascended; the difficult places of the earth are mountains, rivers, hills, and mounds. Kings and princes arrange, by means of such strengths, to maintain their territories. Great indeed is the use of (what is here) taught about seasons of peril.
六條線各有一句判斷。閱讀次序初→上；卦象由下而上，看左側的卦。One statement per line, read from the first line to the top. The figure is drawn bottom-up — watch the rail.
習坎，入于坎窞，凶。
重坎之中，進入坎中之坎（最深處），凶。 初六在險之始又陷入更深的險，是險上加險。
The first SIX, divided, shows its subject in the double defile, and (yet) entering a cavern within it. There will be evil.
習坎入坎，失道凶也。
重坎入坎，是失了正道，故凶。
'In the double defile, he yet enters a cavern in it':—he has missed his (proper) way, and there will be evil.
坎有險，求小得。
坎中有險，求小的可以得到。 九二居中，在險中不求大，只求小，尚可有得。
The second NINE, undivided, shows its subject in all the peril of the defile. He will, however, get a little (of the deliverance) that he seeks.
求小得，未出中也。
求小可得，是因為還沒走出中位。
'He will get a little (of the deliverance that he seeks)':—he will not yet escape from his central place (in the trigram).
來之坎坎，險且枕，入于坎窞，勿用。
來來去去都是坎，險而且不穩，進入坎中之坎，不宜妄動。 六三處在上下兩險之間，動也險，不動也險，但一動必陷入更深，所以說「勿用」。
The third SIX, divided, shows its subject, whether he comes or goes (=descends or ascends), confronted by a defile. All is peril to him and unrest. (His endeavours) will lead him into the cavern of the pit. There should be no action (in such a case).
來之坎坎，終无功也。
來去都是坎，終究無功。
'Whether he comes or goes, he is confronted by a defile':—he will never (in such circumstances) achieve any success.
樽酒簋貳，用缶，納約自牖，終无咎。
一樽酒、兩個簋（食器），用瓦器裝，從窗戶這樣簡約的通道送入，最終無咎。 六四身在險中而與九五相應，用最簡樸的方式維繫與君位的關係，故無咎。
The fourth SIX, divided, shows its subject (at a feast), with (simply) a bottle of spirits, and a subsidiary basket of rice, while (the cups and bowls) are (only) of earthenware. He introduces his important lessons (as opportunity is afforded) by a window. There will in the end be no error.
樽酒簋貳，剛柔際也。
樽酒簋貳，是剛柔之際（六四與九五相接）。
'(Nothing but) a bottle of spirits and a subsidiary basket of rice':—(these describe) the meeting at this point of (those who are represented by) the strong and weak lines.
坎不盈，祗既平，无咎。
坑裡的水沒有漫出來，只是漲到與岸齊平，無咎。 九五居君位，身在險中而守得住中道，不貪滿，險也就慢慢過去。
The fifth NINE, undivided, shows the water of the defile not yet full, (so that it might flow away); but order will (soon) be brought about. There will be no error.
坎不盈，中未大也。
坎不盈，是中道尚未大顯。
'The water of the defile is not full (so as to flow away)':—(the virtue indicated by) the central situation is not yet (sufficiently) great.
係用徽纆，寘于叢棘，三歲不得，凶。
用繩索綑縛，放在荊棘叢中，三年不得脫身，凶。 上六是險之終，非但沒有走出，反而被困，是最嚴重的結局。
The topmost SIX, divided, shows its subject bound with cords of three strands or two strands, and placed in the thicket of thorns. (But) in three years he does not learn the course (for him to pursue). There will be evil.
上六失道，凶三歲也。
上六失道，凶延續三年。
'(The topmost six shows its subject) missing his (proper) course':—the evil will last three years.
把象套到你的情境，取一個可行的下一步。Apply the image to your situation; take one practical step.
重重的水，一道險接一道險，但水自己不滿溢，不失信。
Water upon water — peril after peril, yet water itself never overflows and never loses its course.
坎是八純卦之一，自身對稱（上下顛倒仍是坎），沒有綜卦。錯卦是第三十卦離（純火、純明）。坎與離是易經裡最重要的一對，險與明、暗與顯、北與南。讀坎時也該想到離：你此刻是在險中，還是在明中？Kan is one of the Eight Pure Hexagrams, self-symmetric (read upside-down still gives Kan) — no inverse hexagram. Its opposite is Li (30, pure fire / pure brightness). Kan and Li are among the Yijing's most important pairings — peril and clarity, darkness and brightness, north and south. Reading Kan implies reading Li — are you currently in peril or in clarity?
坎卦教人在重險之中怎樣行走。卦辭「維心亨」點出要害：險象環環相扣時，唯一還能通達的是那顆心，內在一旦失守，比任何外在的失利都致命。大象「常德行、習教事」給出日常功課：把險當練習場看待，一次次過險便是一次次演習，別把它只當災難場。九五「坎不盈」再補一句分寸：在險中守住中道，不過頭、不滿溢，險自己會漸漸平息。最怕的是初六與上六，一頭栽進「入窞」與「叢棘」，落入險中之險。
Kan teaches 'walking peril within peril.' Three operations: (1) the judgment 'only the heart penetrates' — only the heart passes through doubled peril. Losing the heart is more fatal than losing externally. (2) The Great Image 'keep virtue constant in conduct, practice the work of instruction' — treat peril as practice ground, not disaster zone. (3) Line 5's 'the pit not yet full' — hold the central path in peril, don't overflow / don't overdo, and the peril levels itself. The deepest failures: lines 1 and 6, 'entering the cavern' and 'the thicket of thorns' — falling into peril within peril.
把坎讀成「我倒楣了，命不好」，是誤讀。坎不是命運，是結構性的重險，配著結構性的處險之道。最大的失誤是在險中焦急、失了心，一旦心失，就進入初六「入窞」的處境（入坑中之坑）。坎卦教的是：保住心、守中道、反覆練習，險終究會過去。
Misreading Kan as 'I'm cursed / fate is bad' — wrong. Kan is not destiny; it is structural doubled peril paired with a structural way through. The deepest failure is anxiety / heart-loss in peril — once the heart is lost, you enter line 1's state of falling into the cavern within the pit. Kan's teaching: hold the heart + central path + repeated practice, and peril must pass.
坎，險也；重坎，重險也。處重險而能不失其信，唯心通而已。剛中而不陷，所以「行有尚」。聖人於坎之時，明守心之道：險不可盡免，但心可不失。
Kan is peril; doubled Kan is doubled peril. Dwelling in doubled peril and yet not losing one's sincerity — only the heart penetrates. The firm-and-central does not fall in — hence action is honored. In the time of Kan, the sage clarifies the way of guarding the heart: peril cannot be entirely avoided, but the heart can avoid being lost.
重險謂之坎。處險之道，貴在剛中而不失其常。「習」者，重也，又練也；險而又練之，乃可出險。聖人於此立教：心常其所守，行常其所守，斯可不失於險。「常德行、習教事」者，正謂此也。
Doubled peril is called Kan. The way of dwelling in peril values firmness-and-centrality without losing one's constancy. The name's word xi means 'doubled' and also 'practiced' — peril repeated and practiced yields the way out. Here the sage establishes a teaching: the heart constant in what it guards, action constant in what it guards — so one is not lost in peril. 'Keep virtue constant in conduct, and practice the work of instruction' is precisely this.
習，重也。坎，陷也。陽陷陰中，重之則險矣。「有孚」者，內有真實之心；「維心亨」者，唯心可以通也；「行有尚」者，行則有功。聖人於險中以剛中為主，故曰「維心亨」。
Xi means 'doubled.' Kan means 'fall into.' Yang falls amid yin; doubled, this is peril. Inner sincerity is the true heart within; 'only the heart penetrates' means only the heart can pass through; 'action is honored' means action then yields achievement. In peril the sage takes firm-and-central as master — hence 'only the heart penetrates.'
坎上坎下，險過了還是險，六十四卦裡把「困境」寫得最徹底的就是這一卦。卦辭卻只給了一條出路：「維心亨」。環境通不了，條件也通不了，能通的只剩心。心一亂，平地也是陷阱；心定住了，重險裡照樣走得出腳步。危急時處置事情也是這個次序，先保住心，再談處置。 卦名「習坎」一詞兩讀：既是重重之險，也是拿險來練。險躲不掉，那就把它當練習場，每過一次，心法熟一分；大象「常德行，習教事」落的就是這裡。六爻是一條險中行進的路線：初六摔進坎底，最壞；九二在險中求小得；六三進退都是險，就別動；六四一樽酒、兩簋飯，維持最簡的關係；九五水將平未平；上六被繫三年。讀坎不為避險，是為了認出自己此刻在險的哪一層，把那一層該守的守住。
Kan doubled: peril, and past it more peril — the Yijing's most thorough portrait of being stuck. The judgment offers exactly one way through: 'only the heart penetrates.' The environment won't open and the conditions won't open; what can stay open is the heart. Unsettled, it turns flat ground into a pit; held steady, it finds footing through danger after danger. Handling any crisis follows the same order: secure the heart first, then decide what to do. The name 'Xi Kan' reads two ways: peril doubled, and peril practiced. Since the danger can't be avoided, it becomes the training ground — each crossing seasons the method a little more; the Great Image's 'constant virtue, practiced instruction' lands exactly there. The six lines walk a route through it: into the pit at the bottom, small gains held at two, no move worth making at three, a jug of wine keeping the simplest bond at four, water nearly level at five, three years bound at the top. You read Kan not to escape peril but to recognize which layer of it you stand in, and to hold what that layer asks.
坑穴、險陷之意。卦名重坎，指險難接連而來，是全卦要應對的處境。
Pit, abyss, peril. Trigram ☵: yang trapped between two yin — strength held in peril. Doubled = compounded danger.
反覆、練習之意。「習坎」既指重重之險，也指藉著反覆練習走出險境。
Repeat, practice. The hexagram name 習坎 = 'doubled peril' but also 'practiced peril' — repetition itself is the way through.
內心的誠信。身處重險，外在條件不可靠，唯有守住這份誠信才能通達。
Inner sincerity. In Kan, the only thing that 'flows through' is 孚— external paths are blocked, only the heart penetrates.
坑中更深的小坑。初六、六三「入于坎窞」，指陷入比原本處境更深的險地。
A small cavern within a larger pit. Lines 1 and 3: '入于坎窞' — falling deeper than the surrounding peril, the worst position.
一樽酒、兩份食物，泛指簡樸的飲食。六四以此為喻，說明在險中維繫關係不必鋪張。
A wine vessel + two ritual food baskets. Line 4's image: in peril, simple offerings suffice — don't need elaborate ritual.
窗戶。六四「納約自牖」，指用最簡單、間接的方式，把心意送到對方那裡。
Window. Line 4's '納約自牖' — passing simple gifts through a window: indirect, modest, sincere connection in difficulty.
捆綁用的繩索。上六「係用徽纆」，是險境走到盡頭、被困縛的意象。
Ropes of three / two strands. Line 6's '係用徽纆' — bound by cords. Image of the worst form of capture, in the bramble thicket.
坎是八純卦之一（上下卦相同的三爻卦組成），是八宮體系中坎宮的本宮卦。八純卦在京房卦氣、納甲、風水等漢易體系中，都是重要的起點卦。其他七純卦為乾、坤、離、震、艮、巽、兌。
Kan is one of the Eight Pure Hexagrams (where upper and lower trigrams are identical) — the home-hexagram of the Kan palace in the Eight-Palace system. Pure hexagrams are foundational starting points in Han-era Yi systems: gua-qi (hexagram-and-qi), na-jia (stem-branch attribution), fengshui, etc. The other seven: 1 Qian, 2 Kun, 30 Li, 51 Zhen, 52 Gen, 57 Xun, 58 Dui.
坎與第三十卦離為錯卦，是一對純卦配對。坎是純水、純險，離是純火、純明。水火是自然界的兩大對立，也是易經的重要對應：在後天八卦中坎居北、離居南，是五行水火兩極的象徵。
Kan and Li (30) are opposite hexagrams — paired pure hexagrams. Kan is pure water / pure peril; Li is pure fire / pure brightness. Water and fire are the great natural opposites and a major Yijing pairing — in the Later-Heaven bagua, Kan sits north, Li south, the water-fire poles of the five phases.
彖傳「王公設險以守其國」是易經中少見直接談城防、戰略的句子，說明險不只是自然災難，也是政治設計的工具。城牆、護城河、山隘、關卡，都是「設險」的形式。後世談邊防、內政的人常引此句，主張適度的設防是治國所需。
The Tuan Zhuan's teaching that kings and lords arrange peril to protect their state is one of the Yijing's few direct statements on strategy and defense — peril is not only natural calamity but a tool of political design. City walls, moats, mountain passes, and checkpoints are all forms of 'setting up peril.' Later writers on statecraft have cited this line to argue that reasonable defenses are essential to governing.
「習」是《論語》開篇「學而時習之」的同一個字，意思是反覆練習。坎卦用「習坎」二字暗示，險不是用來避開的，是用來練習的。把重重的險當成練習場，這個想法在傳統教育觀裡並不少見。
The word xi is the same character that opens the Analects: 'to study, and in due season to practice what one has learned.' The hexagram name 'doubled Kan' implies: peril is not to be avoided but to be practiced. Treating doubled peril as 'a field for repeated practice' is a familiar idea in traditional views of education.
你此刻處於什麼樣的重險？是在哪一爻？心還在嗎？
What doubled peril are you currently in? Which line? Is the heart still held?

「維心亨」三字為什麼是整部易經處險之道的經典句？「心亨」與「行亨」差在哪裡？
Why is 'only the heart penetrates' a classic line on dwelling in peril? What's the difference between 'heart-penetrating' and 'action-penetrating'?
