Fire over Thunder
Hexagram 21 shows an obstruction lodged between the jaws that must be bitten through decisively before it can be swallowed and resolved.
THE JUDGMENT
噬嗑：亨，利⽤狱。
Jaws Closing: success. It is fruitful to use the courts — to bring a matter to a clear ruling.
THE IMAGE
雷电，噬嗑；先王以明罚敕法。
Thunder and lightning: Jaws Closing. The ancient kings made penalties clear and set the laws in order.
WHAT THIS HEXAGRAM MEANS
Hexagram 21 arrives in the received sequence after Contemplation (Hexagram 20), where watching and being watched has claried what is really going on. Once a situation is seen clearly, something obstructing it often becomes visible too, and Hexagram 21 addresses exactly that: a hard fact wedged between what should otherwise close smoothly.
The Chinese name 噬嗑, romanized without tone marks as Shi Ke (also seen written Shi He), combines 噬, to bite, and 嗑, to close the jaws to-121
gether; read as one phrase it describes the jaws shutting on whatever sits between them. In some editions the hexagram is also translated as Biting Through. The image is the mouth: an open jaw with something lodged inside cannot close, and a mouth that cannot close cannot function. The obstruction has to be met directly — chewed, judged, or worked through
— rather than avoided, and only then does the natural closing motion resume.
Because the obstacle sits inside the jaw itself, this hexagram speaks less to distant threats than to friction that has become part of the situation: a dispute that needs a ruling, a habit that needs breaking, a claim that needs testing. The classical judgment pairs the gure with legal proceed-ings for this reason. Firm, clear-eyed handling of the obstruction is what allows things to come back together.
THE FIGURE
Hexagram 21 joins Fire over Thunder. Thunder below stirs and moves; Fire above illuminates and claries. Together they describe an obstruction that is rst exposed by movement and then judged in the light — the shock of encountering the problem, followed by the clarity needed to deal with it fairly.
In the six-line diagram, counted from the bottom, a solitary yang line sits at the base, two yin lines rise through the middle, a lone yang line crosses the fourth position, then a yin line and a nal yang line complete the top. That single fourth-line yang, wedged among the surrounding yin lines, is read as the very obstruction the hexagram names — the hard thing caught between the jaws.
THE SIX LINES
Read a line only if it came out moving (a 6 or a 9 in the coin method).
122
A light clamp, caught early BOTTOM LINE
初九：屦校灭趾，⽆咎。
A wooden clamp is tted over the foot, covering the toes: no blame.
The bottom line shows a small restraint — a clamp tted over the foot, just enough to cover the toes — applied to a fault caught at its very start. The commentary reads this as correction so mild it prevents worse trouble later: because the offense is minor and dealt with immediately, no real harm follows. The lesson is to address a small wrongdoing the moment it appears, before it hardens into a pattern that would require far harsher handling. When this line changes, the situation moves toward Advance, Hexagram 35: early, proportionate correction clears the way for visible, steady progress rather than repeated relapse.
2
Biting deep into soft resistance SECOND LINE
六⼆：噬肤灭⿐，⽆咎。
The teeth sink through soft esh until it covers the nose: no blame.
At the second line, the obstruction gives way easily, like tender esh under the teeth, yet the bite goes in deep enough to cover the nose. This describes a case where the person holding authority moves with real force against a weaker or more compliant party. Because the resistance was genuinely light and the correction, though strong, was warranted, no blame follows — but the image warns that ease of victory can tempt someone to apply more pressure than the offense actually required. When this line changes, the reading turns toward Opposition, Hexagram 38: overcorrecting a soft target can produce exactly the estrangement or pushback you were trying to avoid.
123
A tainted bite, held rm THIRD LINE
六三：噬腊⾁遇毒，⼩吝⽆咎。
Chewing dried meat, the jaw meets a tainted spot: mild embarrassment, but no blame.
The third line bites into dried meat and meets a spoiled or bitter patch inside it
— a minor, unpleasant surprise rather than a real crisis. Some embarrassment follows, since the timing and position here are not ideal, yet no lasting blame attaches because the person holds their ground rather than abandoning the effort.
This describes encountering an unexpected complication mid-task and choosing to work through the unpleasant part instead of quitting. When this line changes, it points to Fire, Hexagram 30: pressing on through a sour moment brings you to clarity and illumination once the tainted portion has been dealt with.
4
Hard evidence found in the bite FOURTH LINE
九四：噬⼲胏，得⾦⽮，利艰贞吉。
Chewing dried meat still on the bone, a bronze arrowhead is found inside: it is fruitful to hold rm through hardship; good fortune.
At the fourth line, the bite meets dried meat still xed to the bone — genuinely difficult material — and turns up a bronze arrowhead lodged inside: hard, undeniable evidence of the obstruction's true nature. The obstacle can no longer be minimized; this line, isolated among yielding lines above and below, must hold
rm and accept that the case is genuinely hard before it can be settled with good fortune. There is no shortcut through this position, only steady persistence.
When this line changes, the situation resolves into Sustenance, Hexagram 27: having faced the hard evidence, attention shifts to what will properly rebuild afterward.
124
A costly ruling, rightly made FIFTH LINE
六五：噬⼲⾁，得黄⾦，贞厉，⽆咎。
Chewing dried meat, yellow gold is found within: to persevere is dangerous work, yet there is no blame.
The fth line chews dried meat and nds yellow gold within — a valuable dis-covery, but one that comes with real risk, since enforcing this ruling is dangerous work. Positioned at the center of the upper trigram Fire, this line represents a clear-sighted authority who sees the true stakes of a decision and issues it anyway, aware that rmness may provoke resistance from those it corrects. Holding to what is right despite that danger is what keeps the outcome free of blame.
When this line changes, the reading turns toward Genuineness, Hexagram 25: a ruling made honestly opens onto a state where actions and intentions are unforced and true.
6
A heavy, overdue reckoning TOP LINE
上九：何校灭⽿，凶。
A wooden yoke is tted over the neck, covering the ears: misfortune.
The top line shows a heavier restraint than the rst — a wooden yoke tted over the neck, covering the ears — applied to someone who ignored every earlier, milder correction. Because the wrongdoing has compounded past the point where a light clamp would suffice, the outcome here is stated plainly as misfortune. This is the cost of refusing correction while it was still cheap: a problem once small enough for a clamp now needs a harsh measure that may not fully repair the damage. When this line changes, it moves toward Shock, Hexagram 51: the consequence lands like a sudden jolt, an abrupt reckoning that nally breaks the pattern.
