《南華真經義海纂微》Vol. 4

Human life is finite, but there is no limit to what can be known. To chase inexhaustible knowledge with a limited life is bound to leave one worn out. Knowing this yet still pursuing knowledge only leads further into exhaustion. Do good without craving reputation; avoid wrongdoing without bringing punishment upon yourself. Act in accord with the natural, centered way of things—“yuan du” (following the central course)—and you can preserve the body, keep heaven’s endowment intact, support your kin, and live out your full years.

Guo Xiang’s commentary: Human life has its bounds. Whether lifting something heavy or something light, strength has a limit; those who must win, even when their strength nearly breaks their back, still cannot satisfy their desire. That is what it means that knowledge has no end. What people call “knowing” often arises from straying from each thing’s proper share; when one reaches the utmost depth, one is no longer ruled by this discriminating mind. Utmost depth means letting things develop according to their own allotments without adding a hair’s breadth: even bearing a weight of ten thousand jun, one is unaware of the burden; even facing ten thousand affairs, one does not feel them pressing on oneself. That is the gist of nurturing life.

To seek endless knowledge with a finite life—how could one not be trapped? Already trapped, yet trying to remedy it by pursuing more knowledge only harms one’s nature in the name of nurturing life—a real danger. One must forget the distinction between good and evil, rest in the middle way, let all things unfold naturally, and settle peacefully into what is fitting. Then punishment and fame will not entangle the self, and the inner pattern of life can be preserved. If one takes the middle course as one’s constant rule, nothing need fall outside the way of nurturing life. Nurturing life is simply not overstepping one’s portion—keeping heaven’s endowment and completing one’s years.

Lü Huiqing’s commentary: Life, attached to form, has an end; knowledge, chasing externals, has no end. To pursue knowledge with a finite life is only to fall into exhaustion. Knowing this yet still pursuing knowledge ends in nothing but exhaustion.

When everyone knows beauty is beauty, ugliness appears; when everyone knows good is good, “not good” appears. The split between good and evil arises from knowledge—how far apart are they, really? Only those above do not perform Ren and Yi (benevolence and righteousness) to win a name; those below do not do reckless, perverse things and invite punishment. Put down both sides of the good–evil divide and take only what circumstance unavoidably demands as the constant way—that is opening the heart, dropping cleverness, and resting in the way that does not force knowing. For preserving the body, keeping nature, supporting kin, and completing one’s years, what could be better?

Lin Yidu’s commentary: What has form cannot be made endless through yin–yang transformation; what is formless cannot be exhausted by reckoning. Therefore, to chase boundless knowledge with a finite life is inevitably…

When true nature (one’s authentic original nature) splits apart, the distinction between good and evil arises; once good and evil are fixed, fame and punishment follow. To act virtuously without edging toward the pursuit of fame is the true good in the world; to do wrong without edging toward what incurs punishment is the true evil in the world. Only by conforming to the disposition of nature-and-life (xingming), neither harming nor adding to the myriad things, being one with all things without standing apart, neither slandered nor seeking praise, can fame and punishment find nothing to attach to.

The world has names for goodness because some fall short in conduct, and goodness thereby shows; it has names for evil because some go to excess, and evil thereby shows. Some slight life to pursue great righteousness, only to win a moment’s fame; some crave life and chase profit, stray from the right path, and die young. These are what is called good that approaches fame and evil that approaches punishment—not accord with the disposition of nature-and-life, but a turn toward excess.

Chen Xiangdao’s commentary: Those skilled at nurturing life take the self as host and external things as guest; they do not use a limited life to chase what has no limit, and so avoid peril. They act from the heart-mind without violating nature; what one likes and what benefits the present need not be forcibly cast aside, so one is not driven by fame. They follow their nature without going against each thing’s own preferences; reputation after death is not what they seek, so punishment does not come upon them either. They meet things by the right path, act only when they must, and take that as the norm without extremes—then self and externals are at peace: the self does not go against externals, and externals do not harm the self. Thus they can preserve the body, support their kin, preserve life, and complete their natural years.

The Classic of Changes (Yijing) says: “Good that is not accumulated is not enough to establish a name; evil that is not accumulated is not enough to destroy the self.” From this, doing good need not fail to approach fame, nor doing evil fail to approach punishment. Zhuangzi speaks thus because the “good” he means is not apart from the Dao but only holding to one’s proper share; the “evil” he means is not violating righteousness but differing from good. Laozi said Nangong Chu still faintly harbored “evil.” If evil here is understood in this way, then good can be understood in the same way.

Chen Bixu’s commentary: Long life and early death are different conditions within life’s limit; broad learning and thorough mastery are knowledge without end. The principle heaven gives humans is too deep to see through; what humans force is laborious and full of defects. Therefore the key to nurturing life lies in skillful preservation. To crave fame and chase profit without knowing rest only adds hypocrisy, vainly drains life, and ends in danger. The good that can preserve the self—its principle does not lie near seeking fame; that is, holding to simplicity and making few changes…

Han-yin literati are people of this kind: they harm themselves and go against the way things work, and they are not far from punishment. Those sunk in obsessive pursuits—people like Gongsun Chao and Duke Mu—also belong in this situation.

Neither deliberately doing good nor deliberately doing evil, but following the upright path and taking it as one's constant rule—that is the sage's middle way. In this way one can preserve the body and preserve life, support one's parents, and live out one's natural years. This is the root of nurturing life.

Zhao Xuzhai's note: From youth to prime, from prime to old age, and from old age toward death—this is the limited side of life. Affairs crisscross in every direction, running through past and present and seeming inexhaustible—this is the boundless side of knowledge. If one does not understand true principle, one spends a whole life busily chasing knowledge—a truly perilous course. Life has an end and knowledge can be exhausted; when the body declines, the heart changes with it—is that not lamentable?

Living in the world, doing good may win endless praise, doing evil may draw endless slander. Boyi died for reputation, Robber Zhi died for gain; though the causes of death differ, harming life and injuring one's nature are the same. Evils must not be done, yet good need not be done on purpose either, for deliberate action already involves scheming. One should only go along with the central, balanced course of how things run and make that one's constant rule. "Du" (督) here means the principle of centrality and balance. Before joy, anger, sorrow, and pleasure have stirred, the inner self responds to things and reacts; if what appears outwardly is entirely the natural outpouring of one's original nature, then what shows on the outside is just this state of centrality. This is the meaning of "following one's nature is called the Dao" and "taking the central course as one's constant rule." Among the extraordinary meridians spoken of in Daoism, there is also one called the Governing Vessel (dumai).

Lin's Yanzai kouyi says: Using a limited body to chase boundless thought—scrambling in disorder, when will it ever stop? "Dai yi" means the situation is perilous enough to worry one; while still in danger one keeps calculating and fancying oneself knowledgeable, yet in the end one remains only in peril.

From "in doing good, do not crave fame" through the following lines is precisely the art of nurturing life, and the doctrine Zhuangzi himself practiced. If we speak of doing good, there is nothing close to seeking fame to praise; if we speak of doing evil, there is nothing close to inviting punishment to point at. This matches what the Pianmu chapter says: not deliberately holding to benevolence and righteousness, yet not daring to let oneself go into depravity. Respond when things press close; in responding, harbor no deliberate intent, and take that as constant—then one can preserve the body and preserve life, support one's parents, and live out one's natural years. This is also what Mencius meant: do not change one's resolve because of length or brevity of life; cultivate the self and await what fate brings.

Chu's Guanjian says: The Inner Chapters begin with "Xiaoyaoyou," which treats the learning of fully realizing one's nature and is used to clarify the Dao; next comes "Qiwulun" to discuss exhausting the principles of things….

The previous discussion addressed adapting to change; what follows concerns “Nourishing Life” in theZhuangzi: the crux of sustaining life and cultivating the person is not to spend a finite life in pursuit of what has no limit. Let life unfold in its natural course, free from premature cut-off or obstruction; let knowing return to not-knowing, until one settles into a dim, unfathomable depth. Once the harm that afflicts oneself is removed, what danger remains to fear?

If one can truly do this, one may go along with what people under Heaven call good and go along with what they call bad. Even when one acts, how could one be entangled by the chase for reputation or by punishment?

In living among others, there are indeed times when some good ought to be done and some evil ought to be stopped. Sages who bear the burden of ordering the world must uphold the patterns of the age and help the people toward the good; when they meet with good and evil, they especially have matters they cannot refuse to address: rewarding one person so that all under Heaven are encouraged; punishing one person so that all under Heaven take warning. They reward and punish according to what people under Heaven approve and disapprove, much as Heaven and Earth run the four seasons: in spring and summer things grow, yet this is not treated as a favor; in autumn and winter things wither, yet no resentment is incurred for it. Heaven and Earth show no partiality; cold and heat alternate of themselves; things grow and decline by the season alone—it is simply how the time is, unrelated to favor or grudge.

Hou Yi was skilled at hitting the mark, but not skilled at concealing his reputation; such a pursuit of fame through “good” conduct easily invites punishment. If one could be like a tile that happens to strike someone—after the event, no one bears a grudge—one would not invite punishment. The phrase “establishing De as if it were stolen” (jian de ru tou) comes from theDaodejing: to build up virtue so that it seems slight, inconspicuous.

Some commentators cite “if good is not accumulated, it is insufficient to make a name; if evil is not accumulated, it is insufficient to destroy the person,” holding that doing good may attract reputation and doing evil may attract disaster. Others cite “dare not perform acts of benevolence and righteousness, dare not perform depraved acts,” holding that by not doing these things one will not attract reputation or punishment. The two readings are close in wording but not quite the same in meaning.

This passage is roughly saying: what ordinary people call good and evil often springs from private motive and leaves obvious traces—it is the mark of narrow vision. What sages call good and evil proceeds from the public heart and does not draw a small circle; they act from non-attachment (wu suo zhi), and how could those of shallow insight see through it? Emperor Yao removed the Four Evils; Shang Tang and King Wu of Zhou banished Jie and King Zhou; Confucius executed Shaozheng Mao—all of this shows what sages mean by good and evil. Doing good or evil and thereby attracting reputation or punishment, or refraining from such acts and thereby not attracting reputation or punishment, are simply how affairs stand. The present section is explaining: to act, yet not attract reputation….

People treat fame and punishment—reputation and the executioner’s blade—as the reward and retribution for good and evil; the hearts of sages and worthies simply follow the middle way and accord with heaven’s principle and naturalness. Thus gain and loss cannot disturb them; that is where De (Virtue/Power) finds its home.

The character “督” is glossed as “中” (the center). Here “center” means the state before joy, anger, sorrow, and pleasure have yet to arise—not merely a midpoint between good and evil. If, while the seven emotions (joy, anger, sorrow, fear, love, hatred, desire) have not yet stirred, one can go along with this state and make it a constant path, the mind becomes empty, still, clear, and unobstructed, not bound by being or non-being, and merges with Taiji (the Supreme Ultimate). How could one then fail to know that the body can be preserved, life can be fulfilled, parents can be supported, and one’s natural span of years can be enjoyed?

Guo Xiang explained “督” by “center” but did not spell out the reasoning. Later, Xuzhai cited this aptly: the human body has the governing vessel (督脉), the channel that runs straight up and down along the spine, and the conception vessel (任脉), its paired channel—they are where the root of life is tied. Without deep skill in nurturing life, few can probe this layer. Hence the seam down the center of the back of a garment is also called “督,” as the note on the “Deep Garment” in the Book of Rites shows.

Cook Ding was carving an ox for Lord Wenhui. Where his hand touched, where his shoulder leaned, where his foot stepped, and where his knee pressed—all sounded with a crisp rhythm; when the blade fell, there was a clean, open resonance. Not one move was out of tune, as if matching the beat of the “Sanglin” dance and the measure of the “Jingshou” music.

Lord Wenhui said, “Ah, excellent! Can your skill really have reached such a height?”

Cook Ding laid down his knife and replied, “What I love is the Dao (the Way)—it has long surpassed mere technique. At first, when I carved an ox, all I saw was a whole ox. After three years, I no longer saw the ox as a whole. Now I meet the ox with my spirit, not with my eyes; sense perception stops, and spirit moves as it should. I follow the natural grain of the ox, open the great gaps between tendon and bone, guide the knife into the hollows between joints, and cut along the structure the ox was born with. I never touch where tendon and vein meet or flesh and bone cluster—still less the great bones.

A good cook changes his knife every year, because he hacks at meat; an ordinary cook changes his every month, because he chops bone. My knife has been in use nineteen years; I have carved thousands of oxen, yet the edge is still like fresh from the whetstone. The joints of the ox have space between them, and the blade has no thickness; putting what has no thickness into where there is space, the blade always has room to play. So after nineteen years, the edge is still like new.

Even so, whenever I come to a tangle of sinew and bone where it is hard to proceed, I know it will be difficult. I steady my gaze, slow my motion, and make the stroke light and fine. At one clear sound of parting, the ox falls apart like clods of earth on the ground.”

(Cook Ding) stood holding his knife, looked all around, at ease and content, then wiped the blade and put the knife away. Duke Wen of Wei said: “Excellent! Having heard Cook Ding’s words, I understand the principle of nurturing life.”

Guo Xiang’s commentary says: From “where his hand touched” down to “where it met the junctures of the vessels,” this describes how Cook Ding followed the ox’s grain in applying his skill, so that every move went smoothly. He both conformed to the ox’s structure and matched the rhythm of the music. Cook Ding merely used the craft of butchering as a vehicle for the Great Dao; what he truly cherished was not the craft itself.

At first what met his eyes was nothing but the ox—he had not yet discerned the inner pattern of the ox’s body. Later, he no longer saw the whole ox as one lump; he saw only its patterns and gaps. He met the ox with his spirit, not with his eyes—that is, he was not bound by sensory appearance but aligned directly with the inner rationale of things. “Sensory knowing came to a halt, and the activity of spirit took over” means the observing senses stepped back and let the mind-heart move according to the thing’s own principle.

Cook Ding placed his blade along natural structure, never hacking across or forcing through. Where bone met bone in a joint, he used the knife to split along the gap, opening the joint and revealing the void; then he guided the blade through the space so flesh and bone parted. He followed the ox’s native construction and did not cut at random; the blade moved in the gaps and never struck the slightest obstruction. Thus after nineteen years the edge was still like one fresh from the grindstone.

Whenever he came to a place where sinew and bone crossed and clustered, he focused his attention, slowed his motion, and made the cut very light and gradual. At a single “splash” the ox fell apart. Because he parted along the grain, the blade left almost no mark, and the carcass seemed to fall apart like crumbling earth. When the work was done, he was calm and satisfied, wiped the blade, and put it away. The knife was preserved through proper use; likewise, a person can preserve himself through skillful nurturing of life.

Lü Huiqing’s commentary says: Things hinder one another because they have form; the Dao is unobstructed because it is empty. Before one has heard the Dao, what one sees is nothing but particular things; after hearing the Dao, what one sees everywhere is the Dao. “Meeting with spirit, not looking with the eyes” means one who has heard the Dao understands with the heart-mind, not merely through knowledge and hearsay. When sensory knowing stops and spirit acts on its own, following natural principle—this is the highest reach.

Therefore Cook Ding did not truly fail to see the whole ox; rather, he no longer saw the ox only as a single block. Nothing in the world fails to contain the Dao, and no place is impassable—the principle is just this. “What met his eyes was nothing but the ox,” and the analogy of changing knives harming life, mean that the blade after nineteen years was still like newly sharpened and was not worn down by butchering.

The living body is not a fixed, solid entity to begin with—is that not like the gaps between an ox’s joints? Life too is not something eternally unchanged—is that not like a blade thin and sharp, moving freely in the gaps? The blade finding ample room within the ox—is that not like one who has realized the Dao moving at ease among the myriad things?

Still, whenever Cook Ding met a place where sinew and bone clustered, he also found it hard to manage. This shows that what people fear must not be treated carelessly. So he gathered his spirit and stayed alert, focused his attention, slowed his motion, striving to reach the utmost good….

When putting the knife away, if one remains as cautious as at the beginning, nothing will be spoiled.

The Yidu Commentary says: The ox is a metaphor for the principle of xing and ming (nature and life); the knife is a metaphor for life. Following the principle of xing and ming without acting rashly, life will not be harmed; following the ox’s bodily structure when cutting, without relying on brute force, the knife will not be harmed. Thus Cook Ding’s hand touches and foot steps, and in the rhythm of fast and slow, advance and pause, he always accords with the ox’s inherent structure and natural pattern. This is what is meant by “matching the five tones and responding to music and dance”: Cook Ding lodges subtle principle in the coarse craft of butchering; what he delights in is not the craft itself.

When he first began butchering oxen, what he saw was nothing but a whole ox; after a long time, he no longer saw a whole ox before him, but used spirit-shen to apprehend the ox’s structure. Now he relies solely on spirit-shen to apprehend, no longer looking closely with the eyes; the layout within sinew and bone, between skin and flesh, is already clear in his mind. What Laozi calls “cutting off sageliness and discarding knowledge” means here letting the senses and consciousness cease clinging; what the Yijing calls “swift without haste” means spirit-shen moving freely. He follows natural grain: where there is a large gap he splits apart, where there is a large hollow he guides the blade through. All of this accords with the ox’s original structure—where is there need to show off personal cleverness?

Since that is so, even fine obstacles where sinew and bone interweave and are hard to handle he has never encountered, still less tangled, confused great bones. The good cook and the clan cook, though years in the trade differ in length and knives are replaced fast or slow, suffer the same damage to the blade. “Clan” means many people; “good” means few people; Cook Ding alone may be called a cook whose craft reaches spirit. Using a blade with no thickness to enter where there is space, therefore after nineteen years the edge is still as sharp as if freshly honed on a whetstone.

Where the clan cook cuts is often where flesh and bone bind tight; knowing the blade is hard to wield there, one must be vigilant—focus the spirit, hold still, and slow the movement. This metaphorizes the finest points of xing and ming, hardest to nourish. Cook Ding lifts the knife, looks all around, and is content; the ox is already dismembered, and nothing remains to be done. Wiping the knife clean and putting it away shows that the perfected person (zhiren) deals with affairs only when unavoidable, then withdraws and hides in seclusion.

The Xiangdao Commentary says: With the eyes one sees only the surface of things, not the principle within, so what the eye sees is nothing but an ox; with spirit-shen one apprehends principle and no longer clings to concrete things, and thus one no longer sees a whole ox. What is seen is nothing but the li (principle) of things; therefore one can use a blade with no thickness to enter where there is space and wield the blade freely. Is the way of nourishing life not the same? Store the heart in emptiness and stillness, not…

Align your intention with the inherent patterns of things, and respond with a calm, accommodating attitude that goes with the flow rather than fighting how things naturally change. Where a matter is easy to handle, act in step with the situation without hesitation, so that each move hits the right measure. Where it is difficult, treat it with care and keep watchful awareness. As something nears completion, look closely and weigh the outcome, and finish with caution. When it is done, preserve yourself and withdraw—as Pao Ding (the ancient butcher) properly sheathed his knife. One who is skilled at butchering has cut apart many oxen yet the blade stays unmarred; one who is skilled at meeting affairs may face countless situations yet life is not harmed.

Bi Xu’s commentary says: Only when insight is clear can one penetrate how things work; only when craft is refined can one match the right measure. Pao Ding was originally learning the way of nourishing life; he only used the skill of butchering an ox to grasp it. At first he saw only the whole ox and not the lines within it; later he saw those lines and no longer took the ox as a single lump. He met the ox through spiritual responsiveness, not by relying on the eyes alone. This is the practice of cultivating the inner and setting aside outer distraction: when sensory knowing stops, the work of spirit opens up. Pao Ding followed the ox’s natural grain, grasped its inherent channels, slipped the blade into the gaps between sinew and bone and turned it in the hollows between joints—never striking where sinew and bone cross, still less the thick bones. Thus after nineteen years his edge was still as if freshly honed.

His cuts were so light that the carcass fell open at once, and the ox did not even know it was dead. The butcher reads where the hollows lie and lets the blade turn and travel there, and so displays consummate skill. Can someone who nurtures life not likewise avoid calamity, stay hidden and self-contained, keep the body from harm, and thereby preserve innate nature?

Li Shibiao remarks: Things have no fixed, unchanging substance of their own; their forms naturally part. The Dao is nowhere blocked—why must one deliberately “cut apart” anything? What Zhuangzi calls butchering an ox is leaving fixation on externals so mind merges with the Dao; riding the gaps and following the grain, one never truly hacks with the blade. That is accomplishing “cutting apart” without deliberately cutting apart.

Pao Ding butchered oxen for nineteen years—the span was long; he handled thousands of oxen and countless changes, yet the blade stayed as if newly sharpened. Clinging to surface signs, things shift in an instant; holding to the root, one aligns with the constant Dao. The human body is empty from the start—what blade could be truly real and dependable? All things are likewise empty—what ox has a fixed, unchanging substance? When self and things are forgotten, cutter and what is cut vanish together. Then he need not chop on purpose—broad gaps show themselves; need not guide on purpose—wide openings stand open. When the blade fell, the body split apart without the fatigue of wrestling externals; when he laid the knife down, his heart bore no burden of clinging to things. Finally sheathing the knife was returning to a state of Wuwei (non-action) and non-attachment. From the Dao’s view, butchering an ox never required deliberate doing in the first place.

To free yourself from hindrances, you cannot cling to the two sides of “being hindered” and “removing hindrance.” If you still take yourself to be in the act of removing hindrance, you remain bound by hindrance. Conversely, if you only see hindrance and do not know how to dissolve it, hindrance is still there. Only when you release both the thought of hindrance and the thought of removing it, and let the mind return to emptiness and stillness, are you truly at ease. Roaming in this way beyond the myriad things, what could still obstruct you?

Zhao’s commentary says that when Cook Ding butchered an ox, his advances, retreats, and turns all matched the beat. The channels of the ox’s body meet at the head; cutting from those junctions, each part came apart at once. That is why Lord Wenhui marveled when he heard him. Cook Ding also said that the fineness of his art came from having moved from technique into the Dao. Where it was difficult, he was always wary and restrained: spirit gathered, gaze fixed, movement slowed, the blade hesitant—afraid of the slightest harm. So his knife after nineteen years was still like one just sharpened; others’ knives wear out in a few years or even snap. That is the way of skillful nourishing of life.

Yizhai Oral Explications says that “playing the knife” means the stroke and sound fall in time; “Sanglin” and “Jingshou” are names of tunes. When Cook Ding says he “never saw a whole ox,” he means that looking at the ox he no longer saw one intact animal but saw clearly where the blade could go. “Meeting in spirit” is the spirit-mind’s grasp; “the officials’ knowing stops” means sight and hearing no longer lead, and the unspeaking spirit-mind understands on its own. Cook Ding followed the natural grain of sinew, the gaps between joints, and the hollows—structures already there—and only separated along them, never forcing the knife into tangled sinew and bone or striking large bone.

Even skilled and ordinary cooks differ only in how many years before they change knives; in the end the blade is damaged. That his knife after nineteen years was still as if freshly honed shows almost no harm. He sent a thin edge into the body’s spaces and let the knife run freely without snag. The point is that everything in the world has its natural pattern; follow it and the heart stays settled and is less hurt by things.

The closing turn matters too. Life is not always smooth; in hard times people often panic. Then one should respond gently and go with events, not letting the mind stir rashly; when it is over, do not cling, as if it never happened. That is truly knowing how to nourish life.

The chapter on Cook Ding states the essentials of nourishing life with unusual clarity.

The butcher Ding mastered the measure of his movements and retreats in every moment of walking, standing, sitting, and lying down, never leaving it for an instant. The art of painting does not go beyond this principle either. Affairs great and small in the world all have inner patterns.

When Ding the butcher understood the ox’s patterns, he no longer saw a whole ox before his eyes, and his knife always found gaps where it could move freely. If cultivating life means grasping such patterns, body and mind can be at ease, and effort need not be wasted. When Ding wielded his knife in time with the music, he was following the thing’s pattern; when he set down the knife and answered Lord Wenhui, he had let go of fixation on life and understood the way of nurturing life.

If the mind merely copes with outer things, the eye sees only the ox’s form; if one embodies the Dao and merges with things, one no longer treats the whole ox as a single hard lump. Spirit meets the ox rather than relying on the eye alone, so the blade follows natural grain, using a vacant, still mind—without depending on deliberate knowledge or discrimination. Nineteen years passed, yet the knife was still as sharp as when freshly honed on the whetstone: meaning that when person and thing meet without conflict, life is not harmed; one who knows how to nurture spirit does not decline for long.

Yet whenever he came to tangled sinew and bone, Ding grew especially wary, cautious and careful, until the cut was done. The word “clan” (族) here likens worldly affairs: when matters are tangled and situations knotty, caution matters all the more; only when one has first settled oneself can one respond fittingly.

People chase fine food, fine clothes, fine houses, high rank, and the pleasures of sound and color, thinking this is nurturing life. The more they pursue these, the easier it is to lose life’s root. This is exactly what the text means: tending the body alone is not enough to preserve life.

What Ding loved was the Dao, so he moved freely among things. Even when fortune and misfortune alternated and changes piled up, he could still handle things well, as if dust passed before his eyes. This was because he nourished life’s root: inwardly filled with far-reaching De (virtue/power), outwardly aligned with nature’s vitality. Toward self and things alike he was just right; when the task was done, he returned to empty stillness and Wuwei (non-action). It is like one skilled with a knife who puts the knife away—how could the edge need sharpening every month?

The True Person (真人) worried that later students of nurturing life would drown in silent Wuwei until they could not meet the world or abandon human affairs. If so, few could truly stand in the Way. So the author used the craft of butchering to clarify the teaching; whether the ox was “released” in the end is not the point.

Looking again at “whenever he came to the clan,” it seems that at knotted sinew and bone Ding saw difficulty and immediately grew alert and guarded; yet he still finished properly and never truly got stuck. Li Shibiao’s reading agrees. The punctuation from “xiuran wei jie” onward follows Zhao’s edition.

Even if one adopts another reading, the argument can still hold; only the final three characters “the knife is exceedingly slight” do not read quite smoothly.

When Gongsun Xuansi saw Zuoshi, he was startled and asked, “What sort of person is this? How does he have only one foot?”

Zuoshi replied, “Is this Heaven’s doing, or human doing? It is Heaven’s doing, not human doing. Heaven gave birth to me and made me with only one foot. Human forms differ from the outset; from this one can know that it is Heaven’s doing, not human doing.”

A marsh pheasant takes ten steps to peck one mouthful of food and a hundred steps to drink once; it does not seek to be kept in a cage. Even if a caged pheasant is full of spirit, it still does not relish such a life.

Guo Xiang’s commentary: “Jie” (介) is a term for lameness or having a foot cut off. Zuoshi understood that this was the inescapable decree of fate; to insist on going against what one clearly knows would be human contrivance. Here “du” (独) means that the foot is defective. With Zuoshi’s degree of wisdom, he still could not make both feet whole; since wisdom cannot remedy this, why must one force both feet to be intact? To demand full feet because Zuoshi had wisdom would only trap the mind and harm the body. The consequence of that would be far worse than lameness alone.

When both feet can walk together, that is called “having a pair” (youyu). People with two feet usually do not doubt that this is Heaven’s decree; if having two feet is taken as Heaven’s decree, then one should also know that having a single foot is not something one can decide for oneself. To rest content in the situation that suits oneself is the subtle point of nurturing life—why insist on entering a cage and being fed by others? This passage means: the marsh pheasant, spirited and at ease, lives freely in open country and does not even find anything specially precious in what is called “good.”

Lü Huiqing’s commentary: Zuoshi looked like a man outwardly, but what he received was from Heaven; he stood on a single foot, so when Gongsun Xuansi saw him, he doubted he was an ordinary person. “Heaven gave birth to me and made me with only one foot” means that what he received from nature and fate was originally thus. Those who meet the outer world and whose forms match ordinary people are simply common folk. The marsh pheasant drinking and foraging at ease in the marsh, its mind in accord with Heaven and its fate following its own nature and life, is an analogy; it does not seek to be shut in a cage, showing that even if a caged pheasant is full of spirit, it does not like being controlled and unable to roam freely. No matter how well one is fed in a cage, it cannot compare with the pheasant in the marsh drinking, pecking, and being self-sufficient.

Yidu’s commentary: Heaven gave birth to this person and made him with only one foot, while human forms usually have two. The point is that nurturing life does not lie in preserving the outer form; the key is to keep the spirit vigorous. Thus the marsh pheasant, though it eats and drinks little, does not harm its spirit; abundant food in a cage only becomes a burden on the body. The crux of nurturing the spirit is to follow one’s innate nature. So the ancients lived in a small room, ate one bowl of rice and drank one ladle of water, and took that as enough…

Yuezhengzi (a figure in the Zhuangzi) made this principle clear. The Xiangdao commentary says: "Jie" refers to a one-legged person, someone who cannot connect with outside things and is solitary, with no companion. This is what the Right Master (a Song state official title, here referring to a man who had lost a foot) received from Heaven. His appearance differed from that of ordinary people, which is why Gongwen Xuan made his remarks. The pheasant forages freely in the marsh, but once shut in a cage it grows anxious and haggard. While foraging in the marsh its spirit (Shen) may be called vigorous; in the cage its spirit is still vigorous, yet it is not at ease. In general, those who live in the world and deal with external things cannot be without guardedness, whereas those who leave human affairs and return to the Dao of Heaven are always content. The Right Master was regarded with astonishment by others, yet his spirit remained vigorous and his mind at peace, as we can tell from this. The pheasant's spirit is vigorous but it is not at peace, and from this we know it has been disturbed by people.

The Bixu commentary says: Being born with a defect is the decree of Heaven and cannot be avoided, whereas suffering punishment for wrongdoing is something people bring upon themselves. "Youyu" means "being together with others." This one-legged man suffered misfortune from Heaven. Even if he broke the law, it was because he received a dull and ignorant nature, not because of anything done by human effort. Ordinary people, whose bodies are whole, walk together in company, and it is naturally hard for them to envy him; he has long since forgotten his own ugliness. People do not understand why the changes of worldly affairs arise. When something happens, they are confused about its cause, and once confused they are harmed by external things. If one understands the cause, one simply follows what is natural, the heart holds no fear, and so one is spared repeated harm.

The Zhao commentary says: The Right Master was blind, and "jie" refers to someone who made a living by reading faces. Everyone has eyes and I alone have none; Heaven made me this way, and it is not something human power could bring about. He therefore used the pheasant to console himself. In the marsh, the pheasant walks ten paces before pecking at a bite of food and a hundred paces before taking a sip of water. It cannot forget its scheming mind, because its eyes can see and it fears that outside things will harm it. Guarding against trouble in this way, how could it foresee being shut in a cage and kept by people? This shows that the brightness of one's eyes is not enough to rely on, hence the saying, "its spirit is vigorous, yet it is not at ease." When the spirit rests in the eyes and its radiance shows outwardly, this is called "wang" (vigor). The meaning is that relying on the eyes to guard against trouble still cannot spare one from misfortune, so one is better off like the blind man, who entrusts everything to Heaven.

Yuzhai (the sobriquet of Lin Xiyi) says: The Right Master was a man whose foot had already been cut off, and he held the office of Right Master. "Jie" means "single," referring to having only one foot left after the amputation. The phrase "Is it Heaven, or is it man?" asks whether he was born this way or whether the foot was cut off. This was plainly the work of people, yet he says that Heaven caused him to have only one foot. His meaning is that human bodies all stand and walk on two feet, whereas this man has only one, which is why he differs from ordinary people.

Guo Xiang’s reading of the classics is not a matter of “synchronicity” in the sense of events happening at the same time, but of a shared interpretive horizon: the same text can be understood in more than one way, and the meaning that emerges depends on how one reads it. The passage about the marsh pheasant is not mainly about whether the bird’s body is whole or broken; it is about how the spirit illuminates and how inner De (virtue) is preserved. The discussion of water, wood, and yin-yang is not a lesson in natural science; it is a way of saying that a person of cultivation should not be judged by outward appearance alone. The sage, in harmony with Heaven and Earth, is born of yang qi (vital yang energy)—that is the level at which the argument is meant to work.

The marsh pheasant is not a symbol of a severed foot or of bodily deformity. It stands for a life that follows its own nature: even when finding food and water is hard, it would rather endure that than accept comfortable captivity. “Preserving what is intact” means keeping one’s original nature and inner De from being damaged or lost; it does not mean clinging to an unblemished physical form. The text uses the contrast between freedom and the cage to show that true sufficiency lies in being true to one’s nature, not in external abundance. A severed foot is only an extreme instance of difference in bodily form; what matters for human beings is whether they can, amid such differences, hold fast to the De that belongs to their nature. That is why the discussion turns from the pheasant to the gentleman and the sage: outward appearance is not the standard; what counts is whether one’s way of life accords with the Dao (the Way).

The line that the gentleman “is born of the yang qi of Heaven and Earth” should not be read as a claim about physical birth. It means that the sage’s spirit and conduct are in tune with the creative, yang aspect of the cosmos—aligned with the Dao’s movement of growth and transformation, not trapped in rigid form. On this reading, the chapter’s thread is clear: from the pheasant’s choice, to the warning not to judge by appearance, to the image of the sage born of yang qi—all of it serves the idea that preserving inner nature and De matters more than preserving the body intact. Guo Xiang’s commentary is meant to lift the reader from the literal level to this concern with spirit, De, and alignment with Heaven and Earth; that is the “synchronicity” his reading seeks with the original text—not sameness of wording, but resonance at the level of meaning.
