Chapter Two: "That Which Can Transform a Single Thing Is Called Shen; That Which Can Adapt to a Single Affair Is Called Zhi" -- Discerning Shen and Zhi

Section 1: Exegesis of the Original Text

"That which can transform a single thing is called shen; that which can adapt to a single affair is called zhi."

These two sentences set forth the thesis of the entire passage. With the two categories of shen (spirit) and zhi (wisdom), they govern all that follows.

"Can transform a single thing" (yi wu neng hua) -- "a single thing" means any one thing. "Can transform" means to bring about its transformation, metamorphosis, or evolution. The character hua (transform) in pre-Qin literature carries exceedingly rich connotations. The Xici commentary on the Yijing (Book of Changes) says: "To transform and then to trim -- this is called bian (change)" (hua er cai zhi wei zhi bian). It also says: "In Heaven they become images; on Earth they become forms; and so transformation and change are manifest." The Laozi says: "I take no action, and the people transform of themselves" (wo wu wei, er min zi hua). Hua is change that leaves no trace, evolution that occurs naturally of itself -- as the four seasons turn and all things grow, changing moment by moment yet showing no sign of the process. This is what is meant by hua.

"Is called shen" -- In the pre-Qin context, the character shen does not refer to "gods" or "spirits" in the later religious sense, but to a marvelous operative power that transcends sensory cognition. The Xici commentary says: "That which is unfathomable in the interplay of yin and yang is called shen" (yin yang bu ce zhi wei shen). "Unfathomable" means that it cannot be measured or predicted by ordinary reason. It also says: "Shen is the term used for that which works wonders in all things" (shen ye zhe, miao wan wu er wei yan zhe ye). The Xunzi: Tian lun (Discourse on Heaven) says: "All things obtain their proper harmony and thereby live; all things obtain their proper nourishment and thereby grow. One does not see the process, yet one sees the result -- this is called shen." From this we may see that in the pre-Qin sense, shen denotes that invisible, unfathomable, ineffable yet undeniably real power at work in the transformation of things.

"Can adapt to a single affair" (yi shi neng bian) -- "a single affair" means any one affair. "Can adapt" means to respond flexibly, to make adjustments, to reform. Though bian (change) and hua (transformation) are often used together, in precise pre-Qin usage the two are distinguished. The Xici xia says: "When things reach an impasse, there is change; when there is change, there is free passage; when there is free passage, there is endurance" (qiong ze bian, bian ze tong, tong ze jiu). Bian is deliberate change, change involving the participation of a conscious subject. Hua is spontaneous; bian is purposive. Hua leaves no trace; bian leaves a discernible trail.

"Is called zhi" -- The character zhi (wisdom) in pre-Qin texts is sometimes written as zhi (to know). Pre-Qin zhi does not refer merely to the accumulation of knowledge but to the capacity for cognition, judgment, and adaptive response. The Laozi says: "He who knows others is wise" (zhi ren zhe zhi). The Lunyu (Analects) says: "The wise are free from perplexity" (zhi zhe bu huo). The Sunzi bingfa (Art of War) says: "Know yourself, know your enemy, and in a hundred battles you will never be in peril." Zhi is the capacity to perceive with acuity amid all things and affairs, to respond to change, and to make correct judgments.

Section 2: Why Are Shen and Zhi Treated Together$2

Here we must press a crucial question: why does the Neiye chapter place shen and zhi side by side$3 What is the relationship between them$4

Let us first seek other instances in pre-Qin literature where shen and zhi are coupled.

The Xici shang says: "The Yi (Changes) is that by which the sage plumbs the uttermost depths and investigates the subtlest beginnings. Only because of depth can he penetrate the aspirations of all under Heaven; only because of subtlety can he accomplish the affairs of all under Heaven; only because of shen does he arrive without haste and reach without moving." Here "depth," "subtlety," and shen are marshaled together, with shen placed at the highest level -- arriving without haste, reaching without moving.

The "Tianxia" (All Under Heaven) chapter of the Zhuangzi discusses the ancient arts of the Way: "Whence does shen descend$5 Whence does illumination (ming) arise$6 The sage is born of something; the king achieves something -- all originate in the One." Here shen and ming are paired, and their source lies in "the One."

Chapter 39 of the Laozi says: "Of old, those that attained the One: Heaven attained the One and thereby became clear; Earth attained the One and thereby became tranquil; spirits attained the One and thereby became numinous; valleys attained the One and thereby became full; all things attained the One and thereby came to life; lords and kings attained the One and thereby became the standard of all under Heaven." "Spirits attained the One and thereby became numinous" -- when shen attains the One, it becomes wondrously efficacious.

From all this we may see that in pre-Qin literature, shen is a concept of the highest exaltation, representing the supreme capacity that transcends ordinary cognition. Zhi, by contrast, is the highest expression of human cognitive power. Shen pertains to hua -- formless, traceless transformation; zhi pertains to bian -- purposive, adaptive response.

The Neiye chapter couples shen and zhi precisely to point out that in the cultivation of a human being, there are two supreme capacities: one is shen, the wondrous power to bring about the transformation of all things without leaving a trace; the other is zhi, the power of discernment to adapt to all affairs without losing what is fitting. The former is substance; the latter is function. The former is root; the latter is branch. The former inclines toward stillness; the latter toward movement. When the two are united in one, nothing is beyond reach.

Here we must also note a deeper philosophical point: why does the text say "a single thing can be transformed" rather than "all things can be transformed"$7 Why "a single affair can be adapted to" rather than "all affairs"$8

The answer lies in the word "one" (yi). Pre-Qin philosophy places supreme importance on "one." The Laozi says: "The Dao gives birth to the One; the One gives birth to Two; Two gives birth to Three; Three gives birth to all things." "One" is the initial unfolding of the Dao, the root of all things. "That which can transform a single thing is called shen" means: even when facing a single thing, one can bring about its transformation -- and this is called shen. In other words, the essence of shen does not lie in how many things one can transform, but in the capacity to transform any single thing whatsoever. It is a universal, unconditional power. Likewise, "that which can adapt to a single affair is called zhi" -- what matters is not how many affairs one can handle, but the capacity to respond with fluency to any single affair. It is a universal, unconditional faculty of judgment.

This is precisely the spirit of what the "Tianxia" chapter of the Zhuangzi calls "discerning the beauty of heaven and earth, analyzing the principles of all things" -- not exhausting all things in quantity, but grasping in quality the fundamental laws of their transformation.

Section 3: Pre-Qin Thinkers on Shen -- A Comparison

To understand more deeply the concept of shen in the Neiye, it is useful to compare it with the shen doctrines of other pre-Qin thinkers.

(1) Shen in the Yi Zhuan (Commentary on the Changes)

The Xici shang says: "That which is unfathomable in the interplay of yin and yang is called shen." This definition is remarkably precise. Yin and yang are the fundamental law governing the transformation of all things between heaven and earth, and within their interplay there is an unpredictable, ungraspable, wondrous force -- this is shen.

It also says: "Shen is the term used for that which works wonders in all things." "Working wonders in all things" -- causing all things to transform in unfathomable ways, surging with vitality. Shen is not some entity existing apart from all things; it is the wondrous quality manifest within the transformation of all things.

And again: "He who knows the way of transformation and change -- does he not know what shen accomplishes$9" "Knowing what shen accomplishes" -- apprehending how shen operates. Here the relationship between zhi (knowing/wisdom) and shen is made quite explicit: zhi is the means of apprehending shen; shen is the highest object of zhi. The Neiye chapter's pairing of shen and zhi accords perfectly with the spirit of the Yi zhuan.

(2) Shen in the Laozi

Chapter 6 of the Laozi says: "The spirit of the valley never dies -- this is called the Mysterious Female. The gate of the Mysterious Female is called the root of heaven and earth" (gu shen bu si, shi wei xuan pin). Here the two characters gu shen have been much debated. Gu means empty, void. Gu shen refers to the wondrous force within the void. This force never perishes ("never dies") and is the root from which heaven and earth arise.

Chapter 39 of the Laozi says: "Spirits attained the One and thereby became numinous." When shen attains "the One," it becomes infinitely efficacious. Here the relationship between shen and "the One" is of great importance -- "the One" is the precondition for shen to function. And the Neiye chapter, immediately after "That which can transform a single thing is called shen," proceeds to discuss the practice of "holding to the One," a logical relationship perfectly consistent with this.

(3) Shen in the Zhuangzi

The "Tiandi" (Heaven and Earth) chapter of the Zhuangzi says: "That which penetrates heaven and earth is virtue (de); that which operates in all things is the Way (dao)." It also says: "The ancients who shepherded all under Heaven harbored no desires, and the world had enough; they took no action, and all things transformed; they were fathomlessly still, and the hundred clans were at peace." The phrase "all things transformed" (wan wu hua) echoes precisely the hua in "that which can transform a single thing is called shen."

The parable of "Cook Ding Carving an Ox" in the Zhuangzi: Yang sheng zhu (Nourishing the Lord of Life) is an exemplary illustration of shen. Cook Ding says: "What your servant loves is the Dao -- something that goes beyond mere technique." He also says: "At the present moment, your servant meets the ox with his spirit (shen) rather than looking at it with his eyes; the senses cease to act, and the spirit moves as it wills." Cook Ding carves the ox by "meeting it with spirit" rather than "looking with his eyes" -- this is precisely the concrete embodiment of "that which can transform a single thing is called shen": facing a single ox (one thing), he brings about its transformation into a disassembled state, and the entire process is guided by shen, transcending the level of sense perception and technique.

(4) Shen in the Xunzi

The Xunzi: Tian lun says: "The ranks of stars revolve in succession; the sun and moon shine in alternation; the four seasons take turns presiding; yin and yang effect great transformations; wind and rain are broadly bestowed. All things each obtain their proper harmony and thereby live; all things each obtain their proper nourishment and thereby grow. One does not see the process, yet one sees the result -- this is called shen."

Master Xun's definition is extremely close to the concept of shen in the Neiye. "One does not see the process, yet one sees the result" -- the process of transformation is invisible ("one does not see the process"), but its outcome is visible ("one sees the result"). The invisible power that produces such transformation is shen.

This corresponds perfectly with the meaning of hua: hua is traceless transformation; the process of hua is invisible, but its result is visible. The power that brings about this kind of "invisible-process, visible-result" transformation is shen.

Section 4: Pre-Qin Thinkers on Zhi -- A Comparison

(1) Zhi in the Lunyu (Analects)

Lunyu: Yong ye says: "The wise delight in water; the humane delight in mountains. The wise are active; the humane are still. The wise are joyful; the humane are long-lived" (zhi zhe yao shui, ren zhe yao shan). Here zhi (written as zhi, "to know") is the same as zhi ("wisdom"). The Master contrasts zhi with ren (humaneness): the hallmarks of zhi are activity and joy -- skill in adaptive response, flowing ceaselessly like water.

Lunyu: Wei zheng says: "To know what you know and to know what you do not know -- this is true knowledge" (zhi zhi wei zhi zhi, bu zhi wei bu zhi, shi zhi ye). Genuine wisdom includes a clear awareness of one's own cognitive limitations.

Lunyu: Zi han says: "The wise are free from perplexity" (zhi zhe bu huo). To be free from perplexity is to face the ceaseless changes of all things and affairs, discern right from wrong, and make correct judgments without confusion. This echoes "that which can adapt to a single affair is called zhi" -- to respond with flexibility to any affair without confusion; this is zhi.

(2) Zhi in the Laozi

The Laozi's attitude toward zhi is rather complex. On one hand, the Laozi seems to oppose zhi: Chapter 18 says, "When cleverness and knowledge appear, there is great hypocrisy" (zhi hui chu, you da wei); Chapter 19 says, "Abandon sageliness and discard wisdom, and the people will benefit a hundredfold." On the other hand, the Laozi greatly esteems a higher order of cognitive capacity: Chapter 33 says, "He who knows others is wise; he who knows himself is illuminated" (zhi ren zhe zhi, zi zhi zhe ming); Chapter 47 says, "Without going out of doors, one may know all under Heaven; without peering through the window, one may see the Way of Heaven."

From this it is clear that the zhi the Laozi opposes is worldly cleverness, the arts of cunning; what it esteems is a great wisdom transcending worldly cleverness -- the power of discernment that can know others, know oneself, and know all under Heaven without stepping outside one's door. The zhi spoken of in the Neiye chapter clearly belongs to this latter kind.

(3) Zhi in the Sunzi Bingfa (Art of War)

Sunzi bingfa: Ji pian (The Calculations) says: "The qualities of a general are five: wisdom (zhi), trustworthiness, humaneness, courage, and strictness." Wisdom heads the list of the five virtues of a commander. It also says: "Know yourself and know your enemy, and in a hundred battles you will never be in peril; know yourself but not your enemy, and for every victory you will suffer a defeat; know neither yourself nor your enemy, and every battle will be perilous."

Sunzi bingfa: Xu shi pian (Vacuity and Substance) says: "Water shapes its course according to the terrain; an army achieves victory by adapting to the enemy. Thus an army has no fixed configuration, just as water has no fixed form. He who can win by adapting to the enemy's changes -- this is called shen." Note that Sunzi uses the word shen here! "Adapting to the enemy's changes and winning" -- responding flexibly according to changes in the enemy's situation; this is shen.

This usage is extremely close to the Neiye's "that which can adapt to a single affair is called zhi," and Sunzi's use of shen to describe this supreme capacity for adaptive response further confirms the intimate relationship between shen and zhi in pre-Qin thought.

Section 5: Distinguishing Hua (Transformation) and Bian (Change)

Hua and bian are frequently used together as a compound (bianhua, "transformation and change") in pre-Qin texts, but their meanings have a subtle and important distinction. A thorough analysis of these two concepts will aid in understanding the precise meaning of "That which can transform a single thing is called shen; that which can adapt to a single affair is called zhi."

The Xici xia says: "To transform and then to trim -- this is called bian; to extend and put into practice -- this is called tong (free passage); to raise and set before the people of the world -- this is called enterprise." Here the relationship between hua and bian is clearly distinguished: hua is the naturally occurring process of transformation; "trimming" (cai) is the human act of deliberation and choice; "hua and then cai" -- applying human deliberation and selection upon the basis of natural transformation -- this is what is called bian.

From this we may see:

Hua tends toward the natural, the effortless, the traceless. Like the turning of the four seasons and the growth of all things -- one does not see why they happen as they do, yet they happen.
Bian tends toward the purposive, the deliberate, the active. Like the institutions of a sage-king or the strategies of a general -- adapting to circumstances and making changes.

The Neiye says "that which can transform a single thing is called shen" -- to bring about the natural, spontaneous transformation of a thing requires the power of shen. "That which can adapt to a single affair is called zhi" -- to carry out a purposive adaptation in response to a situation requires the faculty of zhi. Shen corresponds to hua; zhi corresponds to bian.

To press the question further: why is hua paired with wu ("thing") and bian with shi ("affair")$10

Wu ("thing") denotes tangible existences -- mountains and rivers, grasses and trees, birds and beasts, metals and implements. Wu possesses objectivity, stability, and concreteness. To bring about the transformation of a wu requires a power that transcends human manipulation -- this is shen. As the spring wind and rain cause all things to sprout, this cannot be forced by human effort; it is the power of nature's shen.

Shi ("affair") denotes human actions -- governing a state, waging war, engaging in social intercourse. Shi possesses subjectivity, dynamism, and practicality. To respond flexibly to a shi requires the wisdom of perceiving the inner logic of affairs and adapting accordingly -- this is zhi. As when Guan Zhong assisted Duke Huan of Qi in achieving hegemony, every step required precise judgment and flexible response in the face of complex international situations -- this is the exercise of zhi.

Wu paired with hua paired with shen -- the natural transformation of the objective world manifests a wondrous power transcending human action. Shi paired with bian paired with zhi -- the flexible response within the human world manifests the highest capacity of human cognition.

This parallelism and pairing is by no means arbitrary; it reflects the profound insight of pre-Qin thinkers into the cosmos and human life.

Section 6: A Historical Illustration -- Guan Zhong's Shen and Zhi

Since this passage comes from the Guanzi, let us use the career of Guan Zhong himself to illustrate the meaning of shen and zhi.

Guan Zhong's Zhi -- Adaptive Response to Affairs

The Shiji: Biographies of Guan and Yan records Guan Zhong's own words: "When I was in straits, I once went into trade with Bao Shuya, and in dividing the profits I took the larger share for myself. Bao Shuya did not think me greedy; he knew I was poor. I once planned affairs for Bao Shuya that only led to greater difficulty; Bao Shuya did not think me foolish, for he knew that fortune has its favorable and unfavorable turns. I was thrice appointed to office and thrice dismissed by the ruler; Bao Shuya did not think me unworthy, for he knew I had not met my time. I fought in three battles and fled from all three; Bao Shuya did not think me a coward, for he knew I had an aged mother. When Prince Jiu was defeated, Shao Hu died for him, and I suffered imprisonment and humiliation; Bao Shuya did not think me shameless, for he knew that I felt no shame at small indignities but only at the disgrace of not making my name known throughout the world."

Guan Zhong was thrice dismissed from office and fled from three battles without feeling disgraced -- this is precisely the embodiment of "that which can adapt to a single affair is called zhi." Facing adversity, Guan Zhong responded flexibly: retreating when retreat was called for, enduring when endurance was necessary, advancing when the time was right. He did not cling to momentary gains and losses but kept his eye on the larger picture. This capacity for adaptive response is zhi.

Guan Zhong's Shen -- Transforming the State of Qi

After Guan Zhong took up the role of assisting Duke Huan, he carried out a series of reforms. The Guoyu: Qi yu (Discourses of the States: Qi) records Guan Zhong's policies: "He restored the old laws, selecting the good among them and putting them into practice." It further records his economic policies: "He facilitated the flow of goods and the accumulation of wealth, enriching the state and strengthening the army." And his diplomatic policies: "He united the lords nine times and brought order to all under Heaven."

On the surface, Guan Zhong's governance of Qi consisted of a series of specific policy measures. But its fundamental effect was a hua -- a transformation: the state of Qi evolved naturally from an ordinary feudal domain into the hegemon of all under Heaven. This hua was not forced change but the art of working with the current of events, guiding momentum to its natural conclusion. The Lunyu: Xian wen records the Master's words: "Guan Zhong served as minister to Duke Huan, who became hegemon of the lords and brought order to all under Heaven. The people to this day receive the benefits of his work. Were it not for Guan Zhong, we would be wearing our hair unbound and fastening our garments on the left" (wei Guan Zhong, wu qi bei fa zuo ren yi).

What the Master praised was precisely the effect of Guan Zhong's hua -- its influence was deep and enduring, altering the entire order of the world and ensuring the continuation of Chinese civilization. This power, leaving no trace yet reaching far, is precisely shen.
