Hexagram 27—頤YíNourishment

Nourishment is the hexagram of structural reflexivity. The shape is the image: two firm lines at the top and bottom enclosing four yielding lines in the middle — the open mouth in profile. Thunder (Zhen) below, Mountain (Gen) above; the Xiang commentary names the picture directly: 山下有雷，頤 — thunder beneath the mountain. The lower trigram churns; the upper trigram holds still. The hexagram’s whole working image is what happens when restless activity below is contained inside a stable ceiling above, and asks you what you are letting through the jaw between them.

The hexagram statement is unusually self-referential. 觀頤，自求口實 — observe how nourishment proceeds; self-seek the mouthful. The instruction is not to act on the world; the instruction is to examine your own intake. The Tuan commentary widens the scope from the personal to the cosmic: 天地養萬物，聖人養賢以及萬民 — heaven and earth nourish the ten thousand things; the sage nourishes the worthies, and through them all the people. Nourishment is not optional even at the highest level of responsibility. Every result is fed by something that was chosen or left unchosen upstream. The hexagram’s discipline is rigorous choice of what you feed on, because what anyone produces will not exceed the quality of what fed it. For decisions this is the hexagram of the working day’s first hour, the reading you do, the small circle of people whose judgement you trust enough to absorb. The hexagram statement’s 貞吉 — firm correctness fortunate — is conditioned on examining and selecting what passes the jaw, then holding that selection with discipline over time.

The dominant trap is the line-1 picture: leaving the efficacious tortoise. You already have working self-nourishing capacity — a craft, a method, a discipline you actually own — and you abandon it to watch someone else’s mouth. The line is unsparing: 凶, evil. The cost is not hunger; the cost is that the working capacity is forgotten in the act of looking elsewhere for the same thing. The second way it goes wrong is the line-3 trap: 貞凶 — firm-correctness is evil — maintaining a wrong intake with discipline and consistency. A feed that confirms a wrong picture; a circle of advisers chosen for agreement rather than friction; a daily diet of news that exaggerates one particular fear. The steadier the regime, the deeper the damage. The hexagram’s prescription at line 3 is severe and unusual: stop for ten years rather than optimise the broken intake. Both failures share a root: you are not producing a wrong result; you are consuming a wrong input, and the result only looks bad downstream of a source that was never examined.

A note on the question shape this hexagram answers best. Nourishment rewards questions framed around what enters your decisions rather than what leaves them. Reading lists, the people you take counsel from, news intake, social feeds, the morning routine, the team that feeds work upward, the partner whose mood you absorb. It is less useful for questions about how to push harder on a result that its inputs cannot support. For that, re-read with Hexagram 26 — Great Restraint — which addresses the discipline of storing accumulated strength before deploying it. Nourishment presumes the result has already revealed the intake problem. The hexagram is the instruction layer for fixing what feeds the work rather than punishing the work.

The canonical adjacent reading is Hexagram 28 — Great Exceeding (大過) — the self-symmetric pair that follows Nourishment in the King Wen sequence. Where 27 puts firm above and below with yielding in the middle, 28 inverts the configuration: yielding above and below with firm in the middle. The structural rhyme is deliberate. 27 names the discipline of what you take in; 28 names the moment when the load placed on a structure exceeds what the structure can carry — the ridgepole bending under its own weight. Read together the pair tells a clean story: when the intake is wrong (27, line 3), the result will eventually present as Hexagram 28’s critical overload; when the load is critical (28), the cheapest correction is often upstream in 27’s nourishment regime rather than downstream in further effort. The two hexagrams together form the canonical intake-and-load diagnostic for major decisions.

The hexagram’s real lever is intake. Most people try to solve their hardest problems by applying more force at the output — longer hours, harder pushes, more finished work. Nourishment is explicit that this is the wrong end of the system. The result is downstream of what you have been consuming for months; the leverage is in editing the consumption, not in punishing the production. In practice this means auditing the four or five people whose judgement you absorb each week and dropping the ones who consistently feed a wrong picture. It means auditing the news and feeds that are shaping your fears and removing the sources that exaggerate one appetite or dread. For anyone who writes, it means auditing what you read in the months before you write rather than the days before you publish. The line-1 instruction is the same in every domain: stop watching someone else’s mouth and return to the efficacious tortoise already in your possession.

Each Western line of reading approaches Nourishment from a different angle. James Legge transliterates 頤 as “Δ and frames the hexagram within his Confucian moral lens — firm correctness, the proper aliment, the exercise of thought to seek what is right. Richard Wilhelm’s symbolic-philosophical posture reads 27 as “The Corners of the Mouth” or “Providing Nourishment” — the great image of the mouth as the gate through which both speech and food pass, and the discipline of moderating what enters and what leaves. A reading in the lineage of Carl Jung’s 1949 foreword would treat 27 as a marker of the psyche’s intake — what symbolic content the unconscious is being fed — with the open-mouth image as the canonical figure of how the inner life is shaped by what it consumes. Bradford Hatcher’s linguistic project (below) abandons all three framings and returns to the semantic field of 頤 itself — appetites, hungers, nutrition as a science, selecting the input for the output. None of these readings is quoted on this page; the synthesis is YiGram Editorial’s characterization of each tradition’s posture, written so a reader can triangulate the field without us reproducing copyrighted text.

The Western reception of the I Ching has two main lines. The first is James Legge’s 1882 missionary translation in the Sacred Books of the East series — methodical, Victorian, framed around Confucian moral readings. It is the public-domain anchor reproduced above. The second is Richard Wilhelm’s 1923 German translation, prepared in Qingdao in collaboration with Lao Naixuan — sympathetic, philosophical, closer to Daoist intuitions. Cary F. Baynes rendered Wilhelm into English in 1950, with a foreword by Carl Jung that introduced the book to Western psychology as a window onto synchronicity and the unconscious.

We cite these two lines by name to credit the reception history and to help search systems and readers resolve the entities; the Wilhelm/Baynes text itself and Jung’s foreword remain in copyright and are not quoted on this page. A more recent academic-linguistic line is represented by Bradford Hatcher’s Yijing project (1990s–2010s), which appears in the next section under his explicit redistribution permission.

Hatcher organizes each hexagram around six short clusters of keywords that sketch the field of decision and association the Chinese name opens onto. For Hexagram 27 頤, his clusters are:

Appetites, hungers, drives; sustenance, nutrition, nurture, provision, nourishment Meeting needs, furnishing necessities, self-reliance, self-assertion, competence Choices of menu, diet, good taste, selecting the input for output, fostering health Finding the genuine & productive appetites, starving the false; potential energy Appetite and its gratification, nutrition as a science, fostering growth and the true Nutrient and energy cycles, raw material and fuel; hungering properly; G.I.G.O.

Hatcher’s framing is vocabulary-centred rather than narrative — the reader is invited to feel the semantic shape of the Chinese name through the spread of English fragments. For his longer notes and the full glossary entry, read the complete passage on hermetica.info.

Read across the four Chinese traditions, Hexagram 27 names a working posture of structural reflexivity: an actor whose output problems are rooted in intake problems, and whose corrective discipline is to examine and select what passes the jaw before attempting anything else. The Wings give the canonical reading: the open mouth in profile, thunder beneath the mountain, the noble person careful in speech and moderate in eating and drinking. Wang Bi sharpens the structural reading: the four yielding lines in the middle of the hexagram are entirely dependent on the two firm lines at top and bottom, and the moral charge of each yielding line is determined by which firm source it correctly draws from. Zhu Xi reframes the hexagram around the moral arithmetic of nourishment — what is nourished and how — and reads the貞吉 opening as conditional on the correctness of both the diet and the diner. The divinatory manual Bushi Zhengzong sits in the practical najia tradition; YiGram, following it, reads 27 as a marker for questions about intake regimes: health, study, diet, circle of associates, information sources, dependencies. The unified posture across all four sources is the same: Nourishment is a discipline for recognising that the lever on a stuck output is almost always upstream in the input pipeline, and for rebuilding that pipeline with rigorous selection rather than habitual consumption.

The Ten Wings are the canonical Confucian commentary stratum embedded in the received Yijing. For Hexagram 27 the two most directly relevant Wings are the Tuan Zhuan (彖傳, the Judgement Commentary) and the Xiang Zhuan (象傳, the Image Commentary).

Tuan 彖傳: 頤，貞吉，養正則吉也。觀頤，觀其所養也。自求口實，觀其自養也。天地養萬物，聖人養賢以及萬民，頤之時大矣哉。

Nourishment, firm correctness fortunate — nourishing what is correct is fortunate. “Observe Nourishment” — observe what is being nourished. “Self-seek the mouthful” — observe how one nourishes oneself. Heaven and earth nourish the ten thousand things; the sage nourishes the worthies, and through them all the people. Vast is the timeliness of Nourishment.

Xiang 象傳: 山下有雷，頤。君子以慎言語，節飲食。

Thunder beneath the mountain — Nourishment. The noble person accordingly is careful in speech and moderate in eating and drinking.

The Tuan does the structural work: the hexagram statement’s 貞吉 is unpacked as 養正則吉 — nourishing what is correct is fortunate — making clear that the verdict is conditional on the correctness of the intake, not on the act of nourishment itself. The double-observation clause then teaches the reflexive method: examine what is being nourished, and examine how the actor nourishes themselves. The Xiang compresses the whole hexagram into a four-character ethical instruction: 慎言語，節飲食 — careful in speech, moderate in eating and drinking — treating both the outgoing (speech) and incoming (food) passages of the mouth as the same discipline.

Wang Bi (Zhouyi Zhu, 3rd century) reads Hexagram 27 primarily as a structural problem of dependence. The four yielding lines in the middle of the hexagram cannot nourish themselves; they must draw from one of the two firm lines at top or bottom. The moral arithmetic of each line is the correctness of its source: line 2 fails because it reaches in both wrong directions; line 4 succeeds because its downward-looking dependence is structurally appropriate. For Wang Bi the line-3 貞凶 is the hexagram’s most diagnostically important warning — firmness in a wrongly-organised dependence does not produce fortune; it deepens the misallocation.

Zhu Xi (Zhouyi Benyi, 1188) reframes the hexagram around the moral arithmetic of what is nourished. For Zhu Xi the hexagram statement’s instruction to observe is the whole working method: a reading practice that asks the actor to examine both the object of nourishment (what is being grown) and the means (what is being consumed). The hexagram does not resolve into a single recommended diet; it resolves into a disciplined practice of selecting and re-selecting the diet against the actor’s actual purposes. The line-6 由頤 is read as the moral apex of the hexagram: the actor whose nourishment regime is so soundly organised that everyone downstream is fed correctly from it.

The Bushi Zhengzong (Qing-dynasty divinatory manual, 1709) is a practical najia handbook: it casts a hexagram against a concrete question rather than expounding it philosophically. In that spirit YiGram reads 27 for questions about an intake regime — health, diet, study programme, advisory circle, information sources, the people whose judgement the actor absorbs — and treats it as the canonical marker that the question presented, whatever its surface, is actually about what is being consumed rather than what is being produced. The practical recommendation tracks the line position the question lands at: stop watching at line 1; refuse both wrong directions at line 2; suspend action at line 3; focus the tiger glare at line 4; reside in firm-correctness at line 5; lead the crossing from line 6.
