I Ching Hexagram 21: Biting Through - Meaning, Changing Lines and Guidance

I Ching Hexagram 21, Shi He or Biting Through, is Fire above Thunder: an open mouth with something stuck between the teeth that must be chewed through before the jaws can close. Its Judgement grants success and approves the administering of justice, and its six changing lines grade the obstruction by the toughness of the meat.

What does I Ching Hexagram 21, Biting Through, mean?

I Ching Hexagram 21 means that something is lodged between you and the thing you want joined, and the way through is to bite down. The Chinese name is Shi He, from a character meaning to gnaw or chew and a character meaning the jaws coming together. The hexagram 21 meaning starts with its picture. Hexagram 27, The Corners of the Mouth, shows an open mouth: firm lines at the bottom and top for the jaws, four soft lines between them for the empty space. Hexagram 21 is that same mouth with one extra firm line, the yang at the fourth place, sitting between the teeth. Nothing about the mouth is wrong. One thing is in it. That single structural fact drives every reading of i ching hexagram 21. The obstacle is never a mood or a phase. It has a location and usually a name: an unpaid invoice, a clause nobody wants to reread, a sentence that was never said out loud. Biting Through answers that the obstruction is real, that it will not dissolve on its own, and that deliberate pressure on it is the correct move rather than a rash one.

The chewing metaphor is carried out in physical detail across the six lines, which grade difficulty by the toughness of what is being eaten: tender flesh at the second place, dried spiced meat at the third, gristle still on the bone at the fourth, dried lean meat at the fifth. The older and more cured the problem, the harder the text says the bite will be, and the third line, biting on old preserved meat, is the one that meets poison. A second tradition widens i ching biting through beyond conflict. The Great Treatise, the Xi Ci commentary appended to the Yijing, credits the invention of the marketplace to Shi He: the midday market where people gathered goods, exchanged them, and withdrew with each having what they needed. A market is two parties biting through a difference until a deal closes. That reading keeps Hexagram 21 from collapsing into pure punishment.

Is I Ching Hexagram 21, Biting Through, a good omen or a bad one?

Hexagram 21 is favorable but not comfortable. The Judgement grants success outright, and four of the six lines close with no blame or good fortune. What Hexagram 21 refuses to grant is an easy route: the success it promises is attached to an act of chewing, and its one outright misfortune belongs to the line that let the problem harden too long.

What is the obstruction in Hexagram 21, Biting Through?

The obstruction in Hexagram 21 is the yang line at the fourth place, the single strong line sitting inside the open mouth. Remove it and the figure becomes Hexagram 27, The Corners of the Mouth, a clear mouth with nothing in it. In a reading, that line points to one identifiable thing or one identifiable person rather than a diffuse difficulty.

What does the name Shi He mean in Hexagram 21?

Shi He, the Chinese name of Hexagram 21, joins shi, to bite or gnaw, with he, the closing of the jaws. The name is a sequence rather than a description: you gnaw, and then the mouth shuts. James Legge rendered it Gnawing Bite; Richard Wilhelm's version, brought into English by Cary F. Baynes, gives Biting Through.

Which two trigrams form Hexagram 21, and why does Fire over Thunder mean Biting Through?

Hexagram 21, Biting Through, is Zhen (Thunder, the Arousing) below and Li (Fire, the Clinging) above, a fire over thunder hexagram. Li supplies sight. It is the trigram of brightness, clinging, and discrimination, the power to tell one thing from another and to see exactly where the trouble sits. Zhen supplies movement. It is the sudden shock, the stroke that arrives without warning and gets a body moving. Put clarity above and force below and you get a bite that lands where it was aimed. That is why the combination produces Biting Through rather than some vaguer image of struggle. Either trigram alone fails at this task. Li alone illuminates an offense and does nothing about it, which is analysis without teeth. Zhen alone strikes in the dark and hits the wrong target, which is temper. The order matters too: light sits on top, so the judgement is formed in full view before the blow falls rather than justified afterward. In a reading, the trigram pair of Hexagram 21 works as a checklist. Have you established what the obstruction actually is, and are you willing to apply real force to it once you have.

Reverse the two trigrams and the meaning changes completely. Thunder above Fire gives Hexagram 55, Abundance, movement on top and light beneath, producing a blaze at its fullest point and the warning about noon that follows it. Hexagram 21 keeps the light overhead and the shock underneath, which is a working arrangement rather than a peak. By the trigram family scheme of the Shuo Gua commentary, Zhen is the eldest son and Li the middle daughter, so Biting Through pairs impulsive young force with clear-eyed discernment and puts the discernment in the senior position. The Image reads the upper trigram as lightning rather than hearth fire, and that is what makes the pairing snap into focus. Thunder and lightning are one event described twice, the flash that reveals and the crack that is felt.

Which trigram is on top in Hexagram 21, Biting Through?

Li, the trigram of Fire and the Clinging, is the upper trigram of Hexagram 21, and Zhen, Thunder and the Arousing, is the lower. Li is written yang, yin, yang reading upward and occupies places four, five and six, which puts the hexagram's clarity above its force.

Why is Li read as lightning in Hexagram 21 rather than as fire?

Li is read as lightning in Hexagram 21 because the Image pairs it with the thunder of the lower trigram, and lightning is what thunder belongs with. Li covers brightness in general, including hearth fire, sun and the eye, but a fire sitting above thunder makes no natural picture, while lightning above thunder makes one instantly.

What hexagram is Fire over Thunder in the King Wen order?

Fire over Thunder is Hexagram 21, Shi He, Biting Through, the twenty-first figure in the King Wen sequence. Its lines reading from the bottom are yang, yin, yin, yang, yin, yang. It follows Hexagram 20, Contemplation, and precedes Hexagram 22, Grace, which is Hexagram 21 turned upside down.

What does the Judgement of Hexagram 21 say?

The Judgement of Hexagram 21 reads: Biting Through has success. It is favorable to let justice be administered. The second clause uses the word yu, which covers litigation, legal proceedings and the prison itself, so the text endorses formal process, not private retaliation. That endorsement is unusual in the Yijing and is the fastest way to fix the hexagram 21 meaning in mind. Hexagram 6, Conflict, treats going to law as a danger and warns that carrying a dispute to the end brings misfortune. Hexagram 21 says the opposite: bring it to the proper forum and let it be settled there. The difference is structural. In Conflict, two strong forces grind against each other with no legitimate authority in the figure. In Biting Through there is a clear obstruction and a governing line seated to deal with it, so the process has something definite to work on. The Judgement also opens with heng, success or penetration, and grants it unconditionally at the front of the sentence. Hexagram 21 does not make success depend on perseverance the way many hexagrams do. It depends on acting at all.

The ruling line of Hexagram 21 is six in the fifth place, a yielding line in the honored central seat, and that detail governs how the whole Judgement should be applied. The judge in this hexagram is not the hardest line in the figure. Strength sits at the fourth place and at the top, but the seat of decision is soft and central, which traditional commentary reads as penalty proportioned to the offense rather than maximized. Clarity comes from the upper trigram and restraint from the yielding fifth line, and the two together are what makes the administering of justice favorable instead of merely forceful. The hexagram approves the proceeding and names who should preside: the mild party in the central position, working in daylight, applying a stated rule. A correction delivered by the angriest person present is not what i ching biting through describes.

Does Hexagram 21 mean I will win a lawsuit?

Hexagram 21 endorses the process rather than promising the verdict. Its Judgement calls it favorable to let justice be administered, which sanctions taking the matter to a proper forum. What the hexagram guarantees is that the obstruction gets addressed. The soft ruling line at the fifth place suggests a measured outcome rather than a crushing one, for either side.

How does Hexagram 21 differ from Hexagram 6, Conflict, on going to law?

Hexagram 6, Conflict, warns against pressing a dispute to the end and advises meeting the great man instead of forcing a hearing. Hexagram 21, Biting Through, actively favors the administering of justice. Conflict is two strong parties with no legitimate arbiter in the figure; Biting Through has an identifiable obstruction and a ruling fifth line seated to judge it.

Which line rules Hexagram 21, Biting Through?

Six in the fifth place rules Hexagram 21. It is a yielding line in the central seat of the upper trigram, the position of presiding authority. Its softness is read as proportion: the one who decides in Biting Through has full clarity from the Li trigram but no appetite for excess.

What does the Image of Hexagram 21 teach?

The Image of Hexagram 21 reads: Thunder and lightning, the image of Biting Through. So the kings of former times made the penalties clear and gave firm definition to the laws. The instruction is about what happens before the bite, not during it. Clarity is written down in advance, penalties are published, and the rule is put in a form anyone can point to. Then, when the moment arrives, the correction is not a surprise and does not need to be argued from scratch. In practice this is the least mystical instruction in the whole of i ching hexagram 21 and the one most often skipped. A boundary that keeps getting crossed is usually a boundary never stated in language the other party could repeat back. A contract clause everyone remembers differently is not a clause. A household rule enforced only when someone is already annoyed teaches nothing except that the mood is dangerous.

The verb in the second half of the Image, chi, carries the sense of setting in order or issuing an authoritative edict, so the former kings are not inventing new punishments but fixing existing ones in stable, knowable form. That distinction matters for how Hexagram 21 is applied. The hexagram does not recommend escalating the penalty. It recommends removing the ambiguity around it. Read with the Judgement, the sequence is complete: define the rule in the open, then let it be administered when it is broken. Note also that the Image names thunder before lightning, reversing the order of the trigrams in the figure, where Li sits above Zhen. In ordinary experience the sanction registers first and the reason becomes clear a moment later, which is precisely the condition the Image was written to correct. A well-governed situation, in the terms of Hexagram 21, puts the lightning first.

What is the Image text of Hexagram 21, Biting Through?

The Image of Hexagram 21 is: Thunder and lightning, the image of Biting Through. So the kings of former times made the penalties clear and gave firm definition to the laws. It draws on Zhen as thunder below and Li as lightning above, and its whole instruction concerns publishing rules in advance rather than punishing harder.

Why does the Image of Hexagram 21 mention former kings?

The Image of Hexagram 21 invokes the former kings because the Yijing reserves them for institutional acts that outlast one person, such as codifying law. Where an Image says the superior man does something, it addresses private conduct. Here the act is legislative: making penalties knowable before anyone needs to apply them.

What is the practical instruction of Hexagram 21's Image?

The practical instruction of Hexagram 21's Image is to write the rule down and state the consequence before the breach, not after it. In a workplace that means a documented standard; in a household it means an agreement both people can repeat; in a contract it means the clause that nobody wants to reread being read now, while the situation is still calm.

What do changing lines 1, 2 and 3 of Hexagram 21 mean?

The first three hexagram 21 changing lines cover a first offense and the two easiest bites. Nine at the beginning: his feet are fastened in the stocks so that his toes disappear, no blame. This is a minor punishment applied early to someone at the start of a wrong course, cleared of blame because a small restraint now prevents a large one later. It changes Hexagram 21 into Hexagram 35, Progress. Six in the second place: he bites through tender flesh so that his nose disappears, no blame. The obstruction here is soft and the correction easy, but the biter buries his face in the work and goes further than the offense required. Still no blame, because the position is central and correct. It changes into Hexagram 38, Opposition. Six in the third place: he bites on old dried meat and strikes on something poisonous, slight humiliation, no blame. This is the grievance that was left to cure. The line has no authority for the job it has taken on and stirs up resentment when it acts, and the humiliation is called slight because the fault lies in the age of the problem rather than the intention. It changes into Hexagram 30, The Clinging.

Read as a run, these three lines of Hexagram 21 build one argument: the difficulty of the bite is a direct function of how long the problem has been sitting. Nothing at the first place has hardened yet, so the stocks are enough. At the second, the flesh is still tender. By the third, the meat has been preserved so long that it has gone bad, and the correction poisons the person attempting it. A second structural point is worth holding. Lines 1 and 6 are the jaws of the mouth, and they are the only two lines in Hexagram 21 that describe punishment received rather than delivered. The four lines between them do the chewing. So a moving line in the first or sixth place asks if you are the one being corrected, while a moving line in the middle four asks how well you are handling a correction you deliver.

What does the nose disappearing mean in line 2 of Hexagram 21?

In line 2 of Hexagram 21, biting through tender flesh so that the nose disappears means the biter sinks his whole face into an easy task and overdoes it. The obstruction gave way at once and the momentum carried further than the offense warranted. The text still says no blame, because six in the second place is central and correctly placed.

Why does line 3 of Hexagram 21 meet poison?

Line 3 of Hexagram 21 meets poison because it bites on old preserved meat, an image for a grievance that has been kept too long and has spoiled. The line is also yin in a yang place and sits at the top of the lower trigram without real authority, so its attempt at correction provokes resentment rather than settling anything. Slight humiliation, no blame.

What hexagram does line 1 of Hexagram 21 change into?

When nine at the beginning moves, Hexagram 21 becomes Hexagram 35, Progress, as the lower trigram Zhen turns into Kun and leaves Li above Earth. A small restraint applied at the very start of a wrong course clears the way for the steady advance Hexagram 35 describes.

What do changing lines 4, 5 and 6 of Hexagram 21 mean?

The last three hexagram 21 changing lines cover the hardest bite, the judge, and the man who would not listen. Nine in the fourth place: he bites on dried gristly meat and receives metal arrows, it is favorable to be mindful of difficulty and to persevere, good fortune. This is the strongest line in Biting Through and the only one ending in good fortune. It is also the obstruction itself, taking on its own removal. Metal arrows stand for hardness and straightness, the qualities the job demands. It changes into Hexagram 27, The Corners of the Mouth. Six in the fifth place: he bites on dried lean meat and receives yellow gold, perseveringly aware of danger, no blame. This is the ruling line, the presiding judge. Yellow is the color of the center, so the reward names the line's own balanced position, and the warning about danger applies because a soft line holds a hard office. It changes into Hexagram 25, Innocence. Nine at the top: his neck is fastened in the wooden cangue so that his ears disappear, misfortune. This is the only outright misfortune in Hexagram 21, and it belongs to the offender who stopped hearing warnings. It changes into Hexagram 51, The Arousing.

The distance between the first line and the sixth is the moral spine of i ching biting through. At the beginning, stocks cover the toes and the verdict is no blame. At the top, the cangue covers the ears and the verdict is misfortune. The Great Treatise makes the connection explicit, observing that the inferior man thinks small good deeds bring no benefit and so does not do them, and thinks small wrongs do no harm and so does not give them up, until the wrongs accumulate past covering and the guilt past undoing. It then quotes this hexagram's top line as the illustration. That is the strongest textual anchor in the whole of Hexagram 21, and it explains why the first line escapes blame so easily. What makes the sixth line fatal is the deafness rather than the size of the offense, which is why it changes into Shock.

What do the metal arrows mean in line 4 of Hexagram 21?

The metal arrows in line 4 of Hexagram 21 stand for hardness and straightness, the qualities needed to bite through gristle on the bone. Traditional commentary also connects them to an old judicial custom in which a party to a hearing deposited a bundle of arrows, so the image carries both the character required and the standing to be heard.

What does yellow gold mean in line 5 of Hexagram 21?

Yellow gold in line 5 of Hexagram 21 names the line's own position. Yellow is the color of the center, and six in the fifth place is the central, honored seat, while gold indicates weight and firmness in a yielding line. The reward is the judge being given the substance the office requires.

Why is line 6 of Hexagram 21 misfortune when line 1 is no blame?

Line 1 of Hexagram 21 puts stocks on the feet and stops a wrong course before it hardens, so the text says no blame. Line 6 puts a cangue over the neck that covers the ears, the image of someone who stopped hearing correction until the offense grew past repair. The difference is not the crime but how late the intervention arrives.

What are the nuclear and opposite hexagrams of Hexagram 21?

The nuclear hexagram of Hexagram 21 is Hexagram 39, Obstruction, and the opposite hexagram is Hexagram 48, The Well. The nuclear figure is built from the inner lines: places two, three and four give Gen, the Mountain, and places three, four and five give Kan, the Abysmal Water, so Water sits above Mountain, which is Hexagram 39. That is a precise inner comment on Biting Through. At the heart of the chewing lies a genuine impasse, water ahead and mountain behind, and Hexagram 39 advises turning back to work on your own position and seeking someone with the standing to help rather than charging forward. The opposite hexagram, made by reversing all six lines of Hexagram 21, is Kan above Xun, Water over Wood, which is Hexagram 48, The Well. Where Hexagram 21 removes an obstruction by force, Hexagram 48 describes a source that never moves and never runs dry, where the only failures are neglecting the shaft and breaking the rope. The pair marks two ways a situation can be kept sound: Biting Through intervenes, The Well keeps the channel clear.

Turn Hexagram 21 upside down and it becomes Hexagram 22, Grace, its partner in the King Wen sequence. Hexagram 21 is enforcement and substance, the bite that makes union possible. Hexagram 22 is form and adornment, what makes union pleasant. The Sequence commentary moves between them by reasoning that things should not be forced together carelessly, so what has been joined must then be given shape. On the other side, Hexagram 21 follows Hexagram 20, Contemplation, on the logic that once something is clearly seen there is something to unite with, and the obstruction between has to be dealt with.

What is the nuclear hexagram of Hexagram 21?

The nuclear hexagram of Hexagram 21 is Hexagram 39, Obstruction, formed by Gen (Mountain) from lines two through four and Kan (Water) from lines three through five. It says the obstruction in Biting Through is real rather than imagined, and it carries Hexagram 39's advice: correct your own position first, then bring in someone with standing.

What is the opposite hexagram of Hexagram 21?

The opposite hexagram of Hexagram 21, made by inverting all six of its lines, is Hexagram 48, The Well, which is Kan over Xun. Biting Through clears an obstruction by applied force; The Well describes an inexhaustible source that asks only for maintenance. The contrast separates intervention from upkeep.

What is Hexagram 21 turned upside down?

Hexagram 21 turned upside down is Hexagram 22, Grace, its paired figure in the King Wen sequence. Biting Through supplies the substance of a union by removing what blocks it, and Grace supplies the form, the ornament and manner that make the union worth having once it exists.

What does Hexagram 21 say about a decision you are weighing?

For a decision, Hexagram 21, Biting Through, says the choice is not really open until you deal with the one thing you have been routing around. Most querents who draw this hexagram are comparing options while quietly excluding the confrontation any of those options would require. The figure answers by pointing at the fourth line: one object sits in the mouth, and every path forward runs through it. So the first move is identification. Name the obstruction in a single sentence with a person or an item in it, and if the sentence comes out abstract you have not found it yet. The second move is proportion, from the ruling fifth line: match the force to the offense rather than to your accumulated irritation. The third move is timing, where the first and sixth lines earn their place. Acting now costs you the toes; acting after several more rounds of avoidance costs you the ears. Hexagram 21 does not ask for aggression. It asks for one deliberate, well-aimed, documented action taken sooner than feels comfortable, followed by the jaws closing.

Hexagram 21 also rules out two popular strategies. The first is waiting for the obstruction to resolve itself, which the hexagram treats as the mechanism behind the third line's poison: preserved meat only gets more dangerous. The second is a general campaign of reform. Biting Through is one bite on one object, and a querent who responds by overhauling everything has misread a figure that is otherwise a perfectly sound mouth. When the fifth line moves and Hexagram 21 becomes Hexagram 25, Innocence, the advice sharpens: act from the plain fact of the matter, without a hidden second agenda, because Innocence punishes the concealed motive. When the fourth line moves and Hexagram 21 becomes Hexagram 27, Nourishment, the message is that once the obstruction is out, the next question is what you put in the mouth instead.

Does Hexagram 21 mean I should confront someone?

Hexagram 21, Biting Through, favors a direct, proportionate correction, so it supports raising the matter. What it does not support is an ambush. The Image requires the standard to be clear before the sanction, and the yielding fifth line sets the tone: state the rule, state the breach, keep the force matched to the offense, and hold it in the open.

What is the wrong way to act on Hexagram 21?

The wrong way to act on Hexagram 21 is to let the matter cure until it spoils, which is the poison in line 3, or to keep chewing after the obstruction is gone, which is line 2 driving its nose into soft flesh. Delay and excess are the two failures the hexagram names. A late, angry correction manages both at once.

How urgent is Hexagram 21, Biting Through?

Hexagram 21 is urgent in the specific sense that its cost rises steeply with delay. The first line applies stocks to the toes and escapes blame; the sixth applies a cangue that covers the ears and ends in misfortune. Nothing in Biting Through improves by being left alone, because its line texts measure difficulty by how long the meat has been cured.

What does Hexagram 21 mean for a relationship and for work?

In a relationship, Hexagram 21, Biting Through, describes one lodged thing rather than a general failure of compatibility. The structure says so plainly: strip out the fourth line and the figure is Hexagram 27, a perfectly good mouth. The bond itself is sound and one specific item is stuck in it, typically a broken agreement, an unrepaid debt of effort, or a subject both people have learned to steer around. Biting Through says the subject has to be raised, and that raising it is repair rather than attack. At work, Hexagram 21 is the standard hexagram for enforcement, overdue accountability, contracts, disputes, audits and negotiation. Its Judgement approves formal process, which in an office means using the actual mechanism rather than a corridor conversation: the written policy, the change request, the escalation path, the clause in the agreement. The Image adds the part most teams skip, defining the standard in advance so the correction has something to rest on. Hexagram 21 rewards the person who can point to the rule and does not need to raise their voice.

Two cautions apply across both areas. First, Hexagram 21 is a single bite, not a program. In a relationship that means one issue at a time rather than a full inventory of grievances delivered at once, which is the third line's spoiled meat served as a meal. At work it means addressing the actual blockage rather than launching a process review around it. Second, the reward lines show who benefits. Line 4 receives metal arrows for doing the hardest chewing and line 5 receives yellow gold for presiding with restraint, so Hexagram 21 pays the person who does the difficult work and the person who keeps the response proportionate. For money questions, the market tradition from the Great Treatise gives Hexagram 21 a commercial reading: terms get negotiated, a difference gets chewed over, and a transaction closes because both sides bit through something rather than because either gave way.

What does Hexagram 21 mean for a relationship that has gone quiet?

For a relationship that has gone quiet, Hexagram 21, Biting Through, blames an unspoken obstruction rather than fading feeling. The fourth line is the thing nobody names. Hexagram 21 says the quiet will not lift on its own, and that naming the item once, directly and proportionately, is what lets the two jaws close again.

What does Hexagram 21 mean in a career or business reading?

In a career or business reading, Hexagram 21, Biting Through, points to enforcement and settlement: an overdue invoice, a contract clause, a disciplinary matter, a stalled negotiation. It favors the formal channel and the written standard. Practitioners also read Hexagram 21 well for deal-making, following the Great Treatise tradition that traces the marketplace to Shi He.

Is Hexagram 21 a good sign for a negotiation?

Hexagram 21, Biting Through, is a workable sign for a negotiation and a poor sign for a comfortable one. The Judgement grants success, and line 4 attaches good fortune to the hardest bite in the figure. Expect resistance in the middle, expect to state your terms in the open, and expect the agreement to close only after the sticking point is chewed through.

Frequently Asked Questions

What does I Ching Hexagram 21 mean in one sentence?

I Ching Hexagram 21, Biting Through, means a specific obstruction sits between you and the union you want, and the situation resolves only when you bite down on it rather than wait it out. The Chinese name Shi He joins a character for gnawing with a character for the jaws closing, so the name holds both the effort and the result.

Is Hexagram 21 Biting Through a yes or a no?

Hexagram 21, Biting Through, reads as a conditional yes. The Judgement opens with heng, success or penetration, so the outcome is granted, but the line texts describe chewing and one describes striking something poisonous. Hexagram 21 says yes to the aim and no to the hope that it arrives without a confrontation somewhere in the middle.

What does Hexagram 21 mean in a love reading?

In a love reading, Hexagram 21, Biting Through, points at one unaddressed thing rather than general incompatibility. The yang line at the fourth place is the object in the mouth; the rest of the figure is a perfectly good mouth. Practitioners read that as one lodged grievance, one broken agreement or one unasked question keeping the two jaws from meeting.

What are the trigrams of Hexagram 21?

Hexagram 21, Biting Through, is built from Zhen (Thunder, the Arousing) below and Li (Fire, the Clinging) above. The Image reads the upper trigram as lightning rather than hearth fire, giving thunder and lightning together: the flash that shows what the offense was and the crack that follows it.

Which changing line of Hexagram 21 is the most favorable?

Nine in the fourth place is the most favorable of the hexagram 21 changing lines. It is the only line in Biting Through whose text ends in good fortune, describing a bite through dried gristly meat and metal arrows received. It is also the hardest bite in the hexagram, which is the point: the reward attaches to the line that takes on the obstruction itself.

What does Hexagram 21 change into when the fourth line moves?

When nine in the fourth place moves, Hexagram 21, Biting Through, changes into Hexagram 27, The Corners of the Mouth, also called Nourishment. That fourth line is the object between the teeth, so removing it leaves an open mouth with nothing in it. Hexagram 27 then asks a different question: not what is stuck, but what you choose to feed yourself.

Is Hexagram 21 about punishment or about eating?

Hexagram 21, Biting Through, is about both, and the two are one image. The inner line texts are eating: tender flesh, dried spiced meat, gristle on the bone, dried lean meat. The Judgement and the outer lines are law: stocks on the feet, a cangue on the neck. The Yijing treats a judicial process as a bite, worked at until the resistance gives way and the parts close.
