The Symbolism of Hexagram 27

Hexagram 頤 (Yí) concerns what is taken in and what is expressed. It describes the system of intake, processing, and output that sustains life and action.

Hexagram 27 Judgment

The Judgment reads:
Original Chinese:
頤，貞吉。觀頤，自求口實。
(Yí, zhēn jí. Guān yí, zì qiú kǒu shí.)
English Translation:
"Nourishment. Correct alignment leads to a favorable outcome. Observe nourishment, and seek what fills the mouth for yourself."

This hexagram directs attention to both intake and source. What is taken in must be examined, and its origin understood.

Sustenance must ultimately be secured by oneself, not passively received or misdirected.

Hexagram 27 Image

The Image reads:
Original Chinese:
山下有雷，頤。君子以慎言語，節飲食。
(Shān xià yǒu léi, yí. Jūn zǐ yǐ shèn yán yǔ, jié yǐn shí.)
English Translation:
"Thunder stirs beneath the mountain: nourishment. The superior person is careful in speech and measured in food and drink."

Thunder initiates movement; the mountain contains it. This reflects controlled intake and controlled expression.

Speech and consumption are parallel systems—both must be governed to maintain balance.

Line 4 Changing

This line reads:
Original Chinese:
顛頤，吉。虎視眈眈，其欲逐逐，无咎。
(Diān yí, jí. Hǔ shì dān dān, qí yù zhú zhú, wú jiù.)
English Translation:
"Disturbed nourishment. Favorable outcome. Focused attention like a hunting tiger. No error."

Nourishment is corrected through precise attention. The tiger image reflects disciplined focus.

When intake is properly directed, balance is restored.

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!
