Translation: One who can understand others possesses wisdom; one who can understand oneself is truly enlightened.
Analysis: The most widely accepted interpretation. "Wisdom" (智) and "enlightenment" (明) form a progressive hierarchy — understanding others requires only ordinary analytical and judgmental ability (wisdom/智), while understanding oneself demands a deeper level of introspection and awakening (enlightenment/明). Wang Bi's commentary precisely identifies this progressive relationship: "知人者，智而已矣，未若自知者超智之上也" ("One who knows others merely has wisdom; this does not compare to one who knows oneself, who transcends beyond wisdom"). Self-knowledge is not another kind of wisdom, but a higher state that surpasses wisdom altogether. Knowing others is directed outward; knowing oneself is directed inward. The outward faculty is "wisdom" (智, cleverness); the inward faculty is "enlightenment" (明, illuminating awareness).

Translation: Discerning others is merely worldly cleverness; understanding oneself is inner illumination.
Analysis: Here "wisdom" (智) takes the pejorative sense of "cunning cleverness" (Laozi often expresses reservations about 智), while "enlightenment" (明) takes the sense of "inner illumination, a supra-sensory awareness." Heshanggong's commentary states: "人能自知贤与不肖，是为反听无声，内视无形，故为明也" ("One who can know their own merits and deficiencies — this is to listen inwardly to the soundless and to see inwardly the formless, and hence is called enlightened"). In this reading, "wisdom" (智) is not entirely positive — being adept at discerning others may be merely worldly shrewdness. "Enlightenment" (明), by contrast, is a mode of inner contemplation that transcends the senses — a deep awakening achieved by returning to the self. This reading implicitly contains Laozi's subtle critique of "the wisdom that knows others": what truly matters is not understanding others, but understanding oneself.

Translation: Understanding others is a cognitive ability; understanding oneself is a state of awareness.
Analysis: A deeper philosophical analysis: "knowing others" and "knowing oneself" differ not only in direction (outward vs. inward) but in their very nature. Knowing others is the subject's cognition of an object, following the logic of epistemology. Knowing oneself, however, is the subject's awareness of itself — it breaks down the subject-object dichotomy, because the knower and the known are one and the same person. Therefore "self-knowledge" cannot be accomplished through conventional cognitive methods (observation, analysis, judgment), but requires a special mode of introspection — this is what Laozi calls "enlightenment" (明). This interpretation resonates with Socrates' philosophical injunction to "Know thyself."

Translation: One who can overpower others merely has force; one who can overcome oneself is truly strong.
Analysis: The most widely accepted interpretation. Perfectly parallel with the preceding sentence: knowing others/wisdom → knowing oneself/enlightenment; overpowering others/force → overcoming oneself/strength. "Force" (力) and "strength" (强) form a progressive hierarchy — defeating others relies on external force (muscles, weapons, political power), while defeating oneself relies on inner strength (willpower, self-discipline, awakening). Heshanggong's commentary states: "人能自胜己情欲，则天下无有能与己争者，故为强也" ("One who can overcome one's own passions and desires — then nothing under heaven can contend with them, hence they are called strong"). Once one has overcome one's own weaknesses of passion and desire, external opponents no longer pose a threat.
Similar views: Heshanggong: "人能自胜己情欲，则天下无有能与己争者，故为强也" ("One who can overcome one's own passions and desires — then nothing under heaven can contend with them, hence they are called strong").
Translation: Using might to dominate others is merely having brute force; being able to surpass oneself is the highest form of strength.
Analysis: Wang Bi offers an in-depth analysis of the difference between "force" (力) and "strength" (强): "胜人者，有力而已矣，未若自胜者无物以损其力" ("One who overcomes others merely has force; this does not compare to one who overcomes oneself, for whom nothing can diminish their strength"). "Overcoming others" has a fatal weakness: your force can be defeated by a greater force. "Overcoming oneself" has no such weakness, because your opponent is yourself — no external thing can diminish your inner strength. Wang Bi further observes: "用其智于人，未若用其智于己也。用其力于人，未若用其力于己也" ("Applying one's wisdom to others is not as good as applying one's wisdom to oneself. Applying one's force to others is not as good as applying one's force to oneself"). The highest use of both wisdom and strength is directed inward, not outward.
Similar views: Wang Bi: "未若自胜者无物以损其力。用其力于人，未若用其力于己也" ("This does not compare to one who overcomes oneself, for whom nothing can diminish their strength. Applying one's force to others is not as good as applying one's force to oneself").
Translation: One who can subdue others merely possesses external force; one who can master oneself is a truly strong person.
Analysis: An interpretation from the perspective of political ethics: "overcoming others" corresponds to governing others (making people submit through coercive force), while "overcoming oneself" corresponds to governing oneself (perfecting oneself through self-discipline). The truly strong person is not a tyrant who can suppress multitudes, but a self-cultivator who can govern themselves. This reading echoes Chapter 17's description of the highest ruler — "百姓皆谓我自然" ("The people all say 'It happened naturally'") — ruling not by suppressing others, but by elevating oneself.

Translation: One who knows contentment is (truly) rich.
Analysis: The most widely accepted interpretation. Laozi redefines "wealth" (富): true richness is not how much one possesses, but feeling content with what one has. A contented poor person is inwardly richer than a greedy wealthy person. Wang Bi's commentary states: "知足自不失，故富也" ("One who knows contentment naturally does not lose what they have, hence they are rich"). Knowing contentment means one does not lose what one already possesses (because one does not grasp for more); not losing is possessing, and possessing is wealth. This is succinct and strikes at the essence of "richness."
Similar views: Wang Bi: "知足自不失，故富也" ("One who knows contentment naturally does not lose what they have, hence they are rich"). Chapter 44: "知足不辱，知止不殆，可以长久" ("Knowing contentment avoids disgrace; knowing when to stop avoids peril — thus one can endure").
Translation: One who knows what is "enough" is spiritually abundant and fulfilled.
Analysis: Here "knowing contentment" (知足) takes the deeper sense of "recognizing limits," and "rich" (富) takes the sense of "spiritual fullness." In this reading, "knowing contentment" is not merely an attitude (feeling satisfied) but a form of wisdom (recognizing the boundlessness of desire and the finitude of material things). The richness this wisdom brings is not merely the absence of material want, but spiritual wholeness and abundance. Heshanggong's commentary states: "人能知足，则长保福禄，故为富也" ("One who can know contentment will long preserve their blessings and fortune, hence they are rich"). Knowing contentment not only enriches the heart but also helps preserve the blessings one already has.
Similar views: Heshanggong: "人能知足，则长保福禄，故为富也" ("One who can know contentment will long preserve their blessings and fortune, hence they are rich").
Translation: One who knows contentment is rich — and one who is truly rich also naturally knows contentment.
Analysis: A deeper dialectical reading: "knowing contentment" and "being rich" are not merely a relationship of condition and result, but a mutually reinforcing cycle. Contentment → feeling rich → greater contentment → greater richness... Conversely, discontent → perpetual feeling of poverty → deeper discontent → deeper poverty... This is a self-reinforcing loop. Laozi's chosen entry point is "contentment" — transforming one's perception of the external world through an inner attitudinal adjustment, rather than pursuing satisfaction through the accumulation of material things.
Similar views: Echoes Chapter 46: "祸莫大于不知足" ("No calamity is greater than not knowing contentment").
Translation: One who strives to act with perseverance has resolve.
Analysis: The most widely accepted interpretation. "Striving to act" (强行) means overcoming difficulties and persisting in practice. A person of resolve does not abandon the path because it is arduous, but pushes forward with determination to the end. Wang Bi's commentary states: "勤能行之，其志必获，故曰强行者有志矣" ("One who diligently persists in practice will surely attain their aspiration, hence it is said that one who strives to act has resolve"). Note that "striving to act" (强行) here does not mean "forcing others," but "compelling oneself" — self-motivation and self-discipline.
Similar views: Wang Bi: "勤能行之，其志必获，故曰强行者有志矣" ("One who diligently persists in practice will surely attain their aspiration, hence it is said that one who strives to act has resolve").
Translation: One who resolutely practices the good Way is devoted to the Tao (道).
Analysis: Heshanggong's commentary specifies "acting" (行) as "practicing goodness": "人能强力行善，则为有意于道，道亦有意于人" ("One who can vigorously practice goodness thereby shows devotion to the Tao, and the Tao in turn shows care for that person"). This reading adds an interactive dimension — you show your heart to the Tao, and the Tao responds in kind. Vigorous practice of the good Way is not merely a one-sided effort; the Tao also reciprocates your sincerity. This sympathetic resonance between the individual and the Tao lends "striving to act" an overtone of religious cultivation.
Similar views: Heshanggong: "人能强力行善，则为有意于道，道亦有意于人" ("One who can vigorously practice goodness thereby shows devotion to the Tao, and the Tao in turn shows care for that person").
Translation: One who strives to practice has resolve — this is an action-oriented complement to the "inward cultivation" of the preceding three sentences.
Analysis: The preceding three sentences (knowing oneself → enlightenment; overcoming oneself → strength; knowing contentment → wealth) all emphasize inner qualities and cognition. This sentence, "one who strives to act has resolve," stresses action and persistence — inner enlightenment, strength, and wealth alone are not enough; they must also be externalized as unwavering practice. "Resolve" (志) is the pivot that converts inner qualities into outward action. At this point the chapter shifts from "turning inward" to "acting outward," completing the full path of self-cultivation: first know oneself, overcome oneself, and know contentment (inner preparation), then strive to act (outward practice).

Translation: One who does not lose the foundation on which they stand will endure.
Analysis: The most widely accepted interpretation. "Their foundation" (其所) refers to the basis on which one establishes oneself — one's proper place, one's essential duty, one's original aspiration. By not being swayed by external temptations and not deviating from one's fundamental ground, one can endure through time. Wang Bi's commentary states: "以明自察，量力而行，不失其所，必获久长矣" ("By using enlightenment to examine oneself, measuring one's strength in action, and not losing one's foundation, one will surely attain endurance"). This sentence follows from the preceding "knowing oneself — overcoming oneself — knowing contentment — striving to act," indicating that holding fast to these inner qualities constitutes "not losing one's foundation."
Similar views: Wang Bi: "以明自察，量力而行，不失其所，必获久长矣" ("By using enlightenment to examine oneself, measuring one's strength in action, and not losing one's foundation, one will surely attain endurance").
Translation: One who does not lose the vital essence bestowed by Heaven will endure.
Analysis: Heshanggong's interpretation from the perspective of Daoist health cultivation: "人能自节养，不失其所受天之精气，则可以长久" ("One who can practice self-restraint and nourishment, not losing the vital essence and Qi (气) received from Heaven, can endure long"). This reading understands "their foundation" (其所) as the vital essence one receives at birth — a share of Heaven-and-Earth's essential Qi (气). Through moderation and health cultivation, one preserves this essence and prevents it from dissipating, thereby attaining longevity. This interpretation carries a strong Daoist health-cultivation flavor, consistent with Heshanggong's characteristic commentary style.
Similar views: Heshanggong: "人能自节养，不失其所受天之精气，则可以长久" ("One who can practice self-restraint and nourishment, not losing the vital essence and Qi received from Heaven, can endure long").
Translation: One who does not betray the Way they uphold will endure.
Analysis: Here "their foundation" (其所) takes the meaning of "the Tao and principles one adheres to." This interpretation emphasizes not position or vital essence, but conviction and principle — no matter what vicissitudes one encounters, as long as one does not abandon one's Tao and principles, one can achieve spiritual endurance. Even as the body ages and status is lost, as long as the heart of the Tao remains unchanged, one has "not lost one's foundation." This reading connects most seamlessly with the following sentence, "死而不亡者寿" — one who holds to the Way endures even beyond death.
Similar views: Directly linked to the following sentence: "死而不亡者寿" ("One who dies but does not perish has longevity").
Translation: One whose body dies but whose spirit is immortal — that is true longevity.
Analysis: The most profound and most widely accepted interpretation. Laozi here transcends the concept of physical life: true "longevity" (寿) is not how many years one lives, but the eternity of one's spirit and influence. Those who influence posterity through their virtue and thought — though their physical body has perished, their spirit lives forever in the world — this is the supreme state of "longevity." This sentence is the culmination and conclusion of the entire chapter, pushing the progressive sequence of "knowing — overcoming — contentment — action — endurance" toward its ultimate expression: "longevity" (寿).
Similar views: The Zuo Zhuan's "Three Imperishables" (三不朽): "太上有立德，其次有立功，其次有立言，虽久不废，此之谓不朽" ("The highest is to establish virtue; next is to establish achievement; next is to establish words. When these persist unfading through time, this is called imperishability").
Translation: One whose body perishes but whose Tao (道) continues — that is true longevity.
Analysis: Wang Bi's commentary states: "虽死而以为生之道，不亡乃得全其寿，身没而道犹存，况身存而道不卒乎" ("Though dead, because the Way of life does not perish, one fully attains longevity. The body perishes but the Tao endures — how much more so when the body still lives and the Tao has not ceased!"). This reading defines "not perishing" (不亡) through the continuation of the Tao — a person's body will decay, but the Tao they upheld and transmitted will not. Even more brilliantly, Wang Bi argues by reverse inference: "身没而道犹存，况身存而道不卒乎?" ("If the body perishes but the Tao still endures, how much more so when the body still lives and the Tao has not ceased!"). This provides a direction for cultivation in the present: to maintain the ceaseless transmission of the Tao while alive is to accumulate "longevity."

Translation: One who is not forgotten after death has true longevity.
Analysis: Here "not perishing" (不亡) takes the meaning of "not being forgotten." This interpretation emphasizes the dimension of social influence — when a person's body has perished, but their thought, achievements, and virtue are still remembered and celebrated by later generations, they spiritually coexist with posterity. Laozi himself is the finest example: his physical body vanished long ago, yet the five thousand characters of the Tao Te Ching have been transmitted for over two thousand years, influencing hundreds of millions of people. This reading aligns with the Zuo Zhuan's concept of the "Three Imperishables" (establishing virtue, establishing achievement, establishing words).
Similar views: Shares the same spirit as the Zuo Zhuan's "Three Imperishables" (三不朽).
Translation: (One who lives according to the proper Way and avoids premature death) has longevity.
Analysis: Heshanggong interprets from the perspective of health cultivation: "目不妄视，耳不妄听，口不妄言，则无怨恶于天下，故长寿" ("When the eyes do not gaze recklessly, the ears do not listen recklessly, and the mouth does not speak recklessly, then one incurs no enmity or hatred in the world, hence one has longevity"). This reading understands "dying but not perishing" as "not dying prematurely due to reckless conduct" — if a person is careful in word and deed and does not provoke enmity, they will not meet a violent end and can naturally live out their allotted years. While this reading lacks the profundity of the preceding interpretations, it is more practical and contains genuine health-cultivation wisdom — "not perishing" here means not the immortality of the spirit, but the body not dying a premature death.
Similar views: Heshanggong: "目不妄视，耳不妄听，口不妄言，则无怨恶于天下，故长寿" ("When the eyes do not gaze recklessly, the ears do not listen recklessly, and the mouth does not speak recklessly, then one incurs no enmity or hatred in the world, hence one has longevity").
Translation: "死" (to die) is the termination of the body; "亡" (to perish) is the vanishing of existence — when the body terminates but existence does not vanish, that is longevity.
Analysis: A philological analysis: "死" (to die) and "亡" (to perish) carry subtle differences in Classical Chinese. "死" refers predominantly to the biological cessation of life (heartbeat stops, breathing stops); "亡" refers predominantly to the ontological vanishing of existence (disappearing completely from the world, ceasing to exist). Laozi precisely distinguishes between these two concepts: a person may "die" (physical termination) but need not "perish" (their spiritual existence does not vanish). The exquisite juxtaposition of these two characters allows merely six characters to bear an extraordinary philosophical weight.

[Core Divergences]
Chapter 33 is one of the most aphoristic chapters of the Tao Te Ching, constructing a complete system of life cultivation in six sentences. The first four sentences form two precisely paired contrasts: "knowing others / knowing oneself" contrasts the direction of cognition (outward vs. inward), and "overcoming others / overcoming oneself" contrasts the application of strength (conquest vs. self-discipline). "One who knows contentment is rich" and "One who strives to act has resolve" then supplement the content of cultivation from the perspectives of attitude and action. The final two sentences, "不失其所者久，死而不亡者寿" ("One who does not lose their foundation endures; one who dies but does not perish has longevity"), drive the chapter toward its ultimate destination — from "endurance" (久, persistence through time) to "longevity" (寿, eternity beyond death), completing the leap from self-knowledge to spiritual immortality. Wang Bi's commentary contributes by precisely revealing the progressive relationship within each pair — wisdom does not match enlightenment ("transcending beyond wisdom"), force does not match strength ("nothing can diminish their strength") — and by pointing out the core meaning of "dying but not perishing" with "身没而道犹存" ("the body perishes but the Tao endures"). Heshanggong, for his part, approaches from the concrete perspective of self-cultivation and health cultivation — knowing oneself is "listening inwardly to the soundless, seeing inwardly the formless"; overcoming oneself is conquering one's passions and desires; knowing contentment is preserving one's blessings; striving to act is practicing goodness — lending the abstract philosophy a practical manual for cultivation. The chapter's most profound sentence, "死而不亡者寿" ("One who dies but does not perish has longevity"), is philologically exquisite: "死" (to die) denotes the termination of the body, while "亡" (to perish) denotes the vanishing of existence — one can die but need not perish. These six characters contain the Daoist ultimate understanding of life, and they serve as the finest footnote to Laozi's own state of "dying but not perishing."
