The Symbolism of Hexagram 18

Hexagram 蠱 (Gǔ) describes a condition of accumulated disorder—something that has been left unattended and has deteriorated over time. It requires deliberate intervention to restore proper structure.

Hexagram 18 Judgment

The Judgment reads:
Original Chinese:
蠱，元亨，利涉大川。先甲三日，後甲三日。
(Gǔ, yuán hēng, lì shè dà chuān. Xiān jiǎ sān rì, hòu jiǎ sān rì.)
English Translation:
"Correction of decay. Origin and smooth progress. It is favorable to undertake a major transition. Three days before, three days after."

This describes a situation requiring active correction of what has been allowed to degrade. Movement is possible, but only through deliberate effort.

The reference to time indicates preparation and follow-through. Repair is not instantaneous—it requires understanding what led to the condition and sustaining the correction beyond the initial change.

Hexagram 18 Image

The Image reads:
Original Chinese:
風行山上，蠱。君子以振民育德。
(Fēng xíng shān shàng, gǔ. Jūn zǐ yǐ zhèn mín yù dé.)
English Translation:
"Wind moves along the mountain: correction of decay. The superior person stirs what is stagnant and cultivates what sustains."

The image shows penetration beneath stillness—movement entering what has become fixed. This reveals underlying disorder.

The response is to activate what has become dormant and rebuild what supports continuity. Correction requires both disruption and renewal.

Line 1 Changing

This line reads:
Original Chinese:
干父之蠱，有子，考无咎，厉终吉。
(Gàn fù zhī gǔ, yǒu zǐ, kǎo wú jiù, lì zhōng jí.)
English Translation:
"Correcting what was handed down. With continuation, there is no error. Risk present. Ending in a favorable outcome."

This line addresses inherited conditions. What has been passed down contains flaws that must be corrected.

The process is demanding, but taking responsibility for repair leads to a favorable outcome.

Line 2 Changing

This line reads:
Original Chinese:
干母之蠱，不可贞。
(Gàn mǔ zhī gǔ, bù kě zhēn.)
English Translation:
"Correcting what was shaped through nurture. It is not favorable to apply rigid persistence."

This line concerns conditions formed through support or care. Correction here requires sensitivity.

Rigid insistence disrupts rather than repairs. Flexibility is necessary to restore balance.

Line 3 Changing

This line reads:
Original Chinese:
干父之蠱，小有悔，无大咎。
(Gàn fù zhī gǔ, xiǎo yǒu huǐ, wú dà jiù.)
English Translation:
"Correcting what was handed down. Regret arises, but no major fault."

Efforts to repair inherited disorder may involve missteps. Not all adjustments are clean.

However, as long as the correction continues, the overall outcome remains sound.

Line 4 Changing

This line reads:
Original Chinese:
裕父之蠱，往见吝。
(Yù fù zhī gǔ, wǎng jiàn lìn.)
English Translation:
"Allowing the inherited disorder to remain. Moving forward brings a constrained outcome."

Failure to correct the condition allows it to persist and deepen.

Continuing without intervention leads to increasing constraint and regret.

21. Biting Through (噬嗑 Shì Kè)

☲ Lí (Fire) — 火 · Radiance

☳ Zhèn (Thunder) — 雷 · Arousing

The Symbolism of Hexagram 21

Hexagram 噬嗑 (Shì Kè) describes removing what obstructs by forceful resolution. It involves judgment, enforcement, and the imposition of consequences to restore order.

Hexagram 21 Judgment

The Judgment reads:
Original Chinese:
噬嗑，亨。利用狱。
(Shì kè, hēng. Lì yòng yù.)
English Translation:
"Biting through. Origin and smooth progress. It is favorable to apply formal judgment."

An obstruction is present that cannot be negotiated away. It must be broken through.

This requires the use of formal judgment and consequence. When enforcement is applied correctly, resolution is achieved.

Hexagram 21 Image

The Image reads:
Original Chinese:
雷電噬嗑。先王以明罰勑法。
(Léi diàn shì kè. Xiān wáng yǐ míng fá chì fǎ.)
English Translation:
"Thunder and lightning meet: biting through. The superior person clarifies penalties and establishes order."

Thunder initiates, lightning illuminates. Together they represent action combined with clarity.

Punishment is not arbitrary—it must be visible, defined, and consistently applied in order to restore structure.

Peace and wisdom on your journey!
