Hexagram 31. Resonance (咸 Xián)

Trigrams

Above

☱ Duì (Lake) — 澤 · Open

Below

☶ Gèn (Mountain) — 山 · Stillness

Symbolic Meaning

咸 (Xián) describes resonance—how one system responds to another through sensitivity and internal alignment. Influence here is not applied force, but the natural transmission of signal between receptive structures.

The mountain below provides stability, while the lake above allows openness and exchange. Together, they form a system where stillness enables accurate reception, and openness allows response. This hexagram models how connection forms through responsiveness rather than control.

Judgment

Original Chinese:
咸，亨，利貞。取女吉。
(Xián, hēng, lì zhēn. Qǔ nǚ jí.)

"Resonance brings smooth progress. It is favorable to remain correctly aligned. Forming a union brings favorable outcome."

This describes a state where mutual responsiveness allows connection to form naturally. Stability is required so that influence is not distorted or forced.

When alignment is genuine, union emerges without friction. The system holds together because its components respond to one another accurately.

Original Chinese:
山上有澤，咸。君子以虛受人。
(Shān shàng yǒu zé, xián. Jūn zǐ yǐ xū shòu rén.)

"The lake rests upon the mountain: resonance. The superior person remains inwardly open and receives others."

The mountain holds still while the lake responds to what it encounters. This pairing creates a system capable of sensing and responding without distortion.

Openness is not passivity, but clarity of reception. By remaining unfilled, one can register external influence accurately and respond appropriately.

Line 1

Original Chinese:
咸其拇。
(Xián qí mǔ.)

"Resonance begins in the toes."

The initial signal is minimal and localized. Influence has begun, but it has not yet developed into meaningful movement.

At this stage, response should remain contained. Premature expansion would distort the signal.

Line 2

Original Chinese:
咸其腓，凶，居吉。
(Xián qí féi, xiōng, jū jí.)

"Resonance reaches the calves. Unfavorable outcome. Remaining still brings favorable outcome."

The signal is spreading, but acting on it too early leads to instability. The system is not yet fully aligned.

Holding position preserves coherence. Movement at this stage introduces error.

Line 3

Original Chinese:
咸其股，執其隨，往吝。
(Xián qí gǔ, zhí qí suí, wǎng lìn.)

"Resonance reaches the thighs. Grasping what follows brings regret. Moving forward leads to a constrained outcome."

Influence has expanded, but attachment begins to interfere with natural response. Control replaces sensitivity.

Forcing continuation breaks alignment. The system becomes reactive rather than responsive.

Line 4

Original Chinese:
貞吉，悔亡。憧憧往來，朋從爾思。
(Zhēn jí, huǐ wáng. Chōng chōng wǎng lái, péng cóng ěr sī.)

"Correct alignment leads to a favorable outcome. Regret resolves. In ongoing exchange, others align with your pattern."

Here, resonance stabilizes and becomes continuous. Signals move back and forth without obstruction.

Because the system remains consistent, others naturally synchronize with it. Alignment spreads without force.

Line 5

Original Chinese:
咸其脢，无悔。
(Xián qí méi, wú huǐ.)

"Resonance reaches the back. No regret."

Influence is now internalized and no longer dependent on surface reaction. It is held within the structure.

Because it is stable and not reactive, there is no error. The system maintains coherence without effort.

Line 6

Original Chinese:
咸其輔頰舌。
(Xián qí fǔ jiá shé.)

"Resonance reaches the jaw, cheeks, and tongue."

Influence has moved into expression—speech and outward signaling. The system now transmits rather than receives.

At this stage, there is risk of distortion. Expression can amplify or misrepresent the original signal if not grounded in prior alignment.
