The following content provides multi-perspective in-depth analysis of each sentence in this chapter, covering traditional commentaries, philological analysis, philosophical interpretation, and other dimensions. Base text: Wang Bi's Commentary on the Daode Zhenjing, Zhengtong Daozang edition
Each interpretation's "Combination" label follows the format "character + meaning index" (e.g., "dàoC-A"), indicating this interpretation uses meaning C of "dào" and meaning A of "". See the full glossary at the end of this chapter: [Appendix: Key Character Glossary].

[Sentence 1] shìzhījiànmíngyuē;(Look at it and it cannot be seen — it is called Yi.)

Chapter 14 · Sentence 1: shìzhījiànmíngyuē

[Interpretation 1] Traditional · High Confidence

Combination: shìA-zhīA-A-jiànA-míngA-yuēA-B
Translation: Look at it but cannot see it; this state is named "Yi" (colorless).
Analysis: The most mainstream interpretation. The Tao (dào) is formless and colorless, transcending the range of visual perception. Heshanggong's commentary: "yuēyáncǎishìérjiànzhī。" ("That which is colorless is called Yi. It means the One has no color and cannot be seen by looking.") Wang Bi also states: "zhuàngxiàngshēngxiǎngnéngsuǒtōngsuǒwǎng。" ("Without form or image, without sound or echo, therefore it can penetrate everywhere and reach all places.") Here "Yi" specifically refers to the invisibility of the Tao.
Similar views: Heshanggong: "yuēyáncǎishìérjiànzhī。" ("That which is colorless is called Yi. It means the One has no color and cannot be seen by looking.")

[Interpretation 2] Novel · Medium Confidence

Combination: shìB-zhīA-A-jiànA-míngA-yuēA-A
Translation: Scrutinize it carefully but cannot see it; this state is called "Yi" (level/even).
Analysis: "shì" (shì) takes the meaning of "to scrutinize," and "" (yí) takes its original meaning of "level/even." Even with the most careful scrutiny, nothing can be seen — it presents a state of "evenness" (no differentiation, no undulation). "Yi" does not mean "disappeared" but rather "so absolutely uniform and level that vision cannot distinguish it." This interpretation implies that the Tao is not nothingness but absolute uniformity.

Chapter 14 · Sentence 1: shìzhījiànmíngyuē

[Interpretation 3] Novel · Low Confidence

Combination: shìA-zhīA-A-jiànB-míngA-yuēA-B
Translation: Look at it, but it does not manifest itself; this is called "Yi."
Analysis: "jiàn" (xiàn) takes the meaning of "to manifest/appear." It is not that human vision is inadequate, but that the Tao itself chooses not to manifest — it actively conceals itself in formlessness. This interpretation endows the Tao with subjectivity: the Tao is not "unable to be seen" but rather "does not reveal itself."
Similar views: Interpretations that gloss "jiàn" as "xiàn" (to appear/manifest).

[Sentence 2] tīngzhīwénmíngyuē;(Listen to it and it cannot be heard — it is called Xi.)

Chapter 14 · Sentence 2: tīngzhīwénmíngyuē

[Interpretation 1] Traditional · High Confidence

Combination: tīngA-zhīA-A-wénA-míngA-yuēA-B
Translation: Listen to it but cannot hear it; this state is named "Xi" (soundless).
Analysis: Parallel to the preceding sentence "shìzhījiàn" (look at it but cannot see it). The Tao is without sound or echo, transcending the range of auditory perception. Heshanggong's commentary: "shēngyuēyányīnshēngtīngérwénzhī。" ("That which is soundless is called Xi. It means the One has no sound and cannot be heard by listening.") The three terms (Yi, Xi, Wei) respectively correspond to the failure of the three senses: sight, hearing, and touch.
Similar views: Heshanggong: "shēngyuēyányīnshēngtīngérwénzhī。" ("That which is soundless is called Xi. It means the One has no sound and cannot be heard by listening.")
Chapter 14 · Sentence 2: tīngzhīwénmíngyuē

[Interpretation 2] Novel · Medium Confidence

Combination: tīngB-zhīA-A-wénA-míngA-yuēA-A
Translation: Listen attentively yet cannot hear it; this is called "Xi" (rare/scarce).
Analysis: "tīng" (tīng) takes the meaning of "to listen attentively," and "" (xī) takes its original meaning of "rare/scarce." The sound of the Tao is extremely rare and elusive; even attentive listening cannot capture it. Chapter 41 of the Tao Te Ching also states "yīnshēng" ("The greatest sound is rare in sound") — the greatest sound is paradoxically inaudible. In this interpretation, "Xi" does not mean "completely soundless" but "so rare as to be virtually nonexistent."
Similar views: The reasoning of Chapter 41's "yīnshēng" ("The greatest sound is rare in sound").
Chapter 14 · Sentence 2: tīngzhīwénmíngyuē

[Interpretation 3] Novel · Low Confidence

Combination: tīngA-zhīA-A-wénB-míngA-yuēA-C
Translation: Listen to it but cannot apprehend it; this is called "Xi" (subtle).
Analysis: "wén" (wén) takes the meaning of "to apprehend/know," and "" (xī) takes the meaning of "subtle." It is not merely that it cannot be heard audibly, but that it cannot be known cognitively — the sound of the Tao is too subtle, exceeding human cognitive capacity.
Similar views: Epistemological interpretations by a few commentators.

[Sentence 3] zhīmíngyuēwēi。(Grasp at it and it cannot be caught — it is called Wei.)

Chapter 14 · Sentence 3: zhīmíngyuēwēi

[Interpretation 1] Traditional · High Confidence

Combination: A-zhīA-A-A-míngA-yuēA-wēiB
Translation: Grasp at it but cannot catch it; this state is named "Wei" (formless).
Analysis: The last of the three senses — touch. The Tao is without form or body; hands cannot touch or seize it. Heshanggong's commentary: "xíngyuēwēiyánxíngtuánchíérzhī。" ("That which is formless is called Wei. It means the One has no physical form and cannot be grasped or held.") "Look at it but cannot see it" (colorless), "listen to it but cannot hear it" (soundless), "grasp at it but cannot catch it" (formless) — these three together completely negate the possibility of knowing the Tao through human sensory perception.
Similar views: Heshanggong: "xíngyuēwēiyánxíngtuánchíérzhī。" ("That which is formless is called Wei. It means the One has no physical form and cannot be grasped or held.")
Chapter 14 · Sentence 3: zhīmíngyuēwēi

[Interpretation 2] Novel · Medium Confidence

Combination: B-zhīA-A-B-míngA-yuēA-wēiA
Translation: Touch it but cannot perceive it; this is called "Wei" (minute/subtle).
Analysis: "" (bó) takes the meaning of "to touch," and "wēi" (wēi) takes its original meaning of "minute/subtle." The Tao does not fail to exist; it is merely too minute — so subtle that even touch cannot perceive it. This interpretation preserves the reality of the Tao while emphasizing its extreme subtlety.
Similar views: Philological interpretations starting from the original meaning of "wēi."
Chapter 14 · Sentence 3: zhīmíngyuēwēi

[Interpretation 3] Novel · Low Confidence

Combination: A-zhīA-A-A-míngA-yuēA-wēiC
Translation: Try to seize it but cannot catch it; this is called "Wei" (concealed).
Analysis: "wēi" (wēi) takes the meaning of "concealed/hidden." The Tao is not formless but actively conceals itself — it chooses not to be captured by human senses. This echoes the interpretation above where "jiàn" is read as xiàn: the Tao actively hides itself beyond form, sound, and body.
Similar views: Echoes "dàoyǐnmíng" ("The Tao is hidden and has no name") in Chapter 41.

[Sentence 4] sānzhězhìhùnérwèi。(These three cannot be fully fathomed, and so they merge into one.)

Chapter 14 · Sentence 4: sānzhězhìhùnérwèi

[Interpretation 1] Traditional · High Confidence

Combination: zhìA-A-hùnA-A
Translation: These three (Yi, Xi, Wei) cannot be investigated further, and so they merge into one.
Analysis: The most mainstream interpretation. The three sensory characteristics — colorless, soundless, and formless — cannot be separately examined or interrogated, because they all point to the same imperceptible existence: the Tao. "Merge into one" (hùnérwèi) indicates that the Tao is a unity transcending sensory categories. Heshanggong's commentary: "hùnsānmíngzhīwèi。" ("Hun means 'to combine.' Therefore the three names are combined into one.")
Similar views: Heshanggong: "hùnsānmíngzhīwèi。" ("Hun means 'to combine.' Therefore the three names are combined into one.")
Chapter 14 · Sentence 4: sānzhězhìhùnérwèi

[Interpretation 2] Traditional · High Confidence

Combination: zhìA-A-hùnB-B
Translation: These three cannot be investigated further, and so they form an undifferentiated whole — that is, the Tao (the One).
Analysis: "hùn" (hùn) takes the meaning of "undifferentiated/primordial" (interchangeable with "hún"), and "" (yī) takes the ontological concept of "the Tao." The emphasis is not that the three are "combined" (passive), but that they are inherently an undifferentiated whole (their natural state). In Heshanggong's system, "the One" () is another name for the Tao.
Similar views: Heshanggong's system, which uses "the One" () as an alternative name for the Tao.
Chapter 14 · Sentence 4: sānzhězhìhùnérwèi

[Interpretation 3] Novel · Medium Confidence

Combination: zhìB-B-hùnA-A
Translation: These three cannot be known through inquiry, and so they blend into a single whole.
Analysis: "zhì" (zhì) takes the meaning of "to obtain," and "" (jié) takes the meaning of "to interrogate/investigate." It is not that they "cannot be investigated to the end" (cognitive limit), but that "answers cannot be obtained through inquiry" (methodological limitation) — using the analytical method of inquiry is incapable of knowing the Tao; one must employ a different, holistic mode of intuition. This interpretation contains epistemological reflection.
Similar views: Heshanggong: "dāngshòuzhījìngqiúzhīshénwènérzhī。" ("One must receive it in stillness, seek it with spirit; it cannot be obtained through questioning.")

[Sentence 5] shàngjiǎoxiàmèi。(Its rising brings no light; its sinking brings no darkness.)

Chapter 14 · Sentence 5: shàngjiǎoxiàmèi

[Interpretation 1] Traditional · High Confidence

Combination: shàngA-jiǎoA-xiàA-mèiA
Translation: Its upper aspect is not bright; its lower aspect is not dark.
Analysis: The Tao transcends the binary opposition of light and darkness. Above, it does not appear bright because of being above; below, it does not appear dark because of being below — it is unaffected by spatial position and does not fall into any category of opposites. Heshanggong's commentary: "yánzàitiānshàngjiǎo。" ("The One in Heaven above is not bright.") "yánzàitiānxiàmèi。" ("The One below Heaven is not dark.")
Similar views: Heshanggong: "yánzàitiānshàngjiǎo。" ("The One in Heaven above is not bright.") "yánzàitiānxiàmèi。" ("The One below Heaven is not dark.")
Chapter 14 · Sentence 5: shàngjiǎoxiàmèi

[Interpretation 2] Novel · Medium Confidence

Combination: shàngB-jiǎoB-xiàB-mèiB
Translation: At its highest it is not clearly discernible; at its lowest it is not obscure or benighted.
Analysis: "jiǎo" (jiǎo) takes the meaning of "clear and distinct," and "mèi" (mèi) takes the meaning of "benighted/ignorant." The Tao is neither completely clear and knowable (not clearly discernible even at its highest) nor completely unknowable (not obscure even at its lowest). It exists in an intermediate state between "knowable" and "unknowable," precisely like "huǎng" (huǎnghū — dimly visible, vaguely present).
Similar views: Wang Bi's dialectical reasoning: "yánxiééryóuchéngyányǒuxiéérjiànxíng" ("If one wishes to call it nothing, yet things come into being through it; if one wishes to call it something, yet its form cannot be seen").

[Sentence 6] shéngshéngmíngguī。(Endless and unnameable, it reverts to nothingness.)

Chapter 14 · Sentence 6: shéngshéngmíngguī

[Interpretation 1] Traditional · High Confidence

Combination: shéngshéngA-míngA-B-guīA-A-A
Translation: (The Tao) stretches on ceaselessly and cannot be named; ultimately it reverts to the state of "no-thing."
Analysis: The most prevalent interpretation. The Tao extends endlessly and inexhaustibly, yet cannot be designated by any name. It ultimately reverts to a state of "no-thing" () that transcends all concrete objects. Heshanggong's commentary: "zhìdāngguīzhīzhì。" ("Wu means substance. It must ultimately revert to the substanceless.")
Similar views: Heshanggong: "shéngshéngzhědòngxíngqióng。" ("Shengsheng means moving and acting without limit.") "dāngguīzhīzhì。" ("It must ultimately revert to the substanceless.")
Chapter 14 · Sentence 6: shéngshéngmíngguī

[Interpretation 2] Novel · Medium Confidence

Combination: shéngshéngA-míngB-A-guīA-B-A
Translation: Stretching on ceaselessly and indescribable, it resolves into the space between "Non-being" () and "things" ().
Analysis: "míng" (míng) takes the meaning of "to describe," and "" (wú) takes the ontological concept. The Tao cannot be described in language; what it resolves into is not simply "nothing" (the absence of things), but the space between "Non-being" (the ontological void) and "things" (concrete objects) — the Tao is neither substantial existence nor absolute nothingness.
Similar views: Wang Bi's dialectical reasoning: "yánxiééryóuchéngyányǒuxiéérjiànxíng" ("If one wishes to call it nothing, yet things come into being through it; if one wishes to call it something, yet its form cannot be seen").

[Sentence 7] shìwèizhuàngzhīzhuàngzhīxiàngshìwèihuǎng。(This is called the form of the formless, the image of the imageless — this is called the dimly visible.)

Chapter 14 · Sentence 7: shìwèizhuàngzhīzhuàngzhīxiàngshìwèihuǎng

[Interpretation 1] Traditional · High Confidence

Combination: A-zhuàngA-zhīA-zhuàngA-A-A-zhīA-xiàngA-A-huǎngA
Translation: This is called the form of the formless, the image of the thingless — this is called the dimly visible (huǎnghū).
Analysis: Although the Tao is without form or image, it is not absolute "nothingness" — it possesses "the form of the formless" (a form transcending all forms) and "the image of the thingless" (an image transcending all material things). "Huǎnghū" (huǎng, or huǎng) is the specialized term describing this mode of existence that seems to exist yet seems not to, seems real yet seems illusory. Wang Bi's commentary: "yánxiééryóuchéngyányǒuxiéérjiànxíngyuēzhuàngzhīzhuàngzhīxiàng。" ("If one wishes to call it nothing, yet things come into being through it. If one wishes to call it something, yet its form cannot be seen — therefore it is called the form of the formless, the image of the thingless.") Heshanggong's commentary: "huǎnghuǎngzhěruòcúnruòwáng。" ("The One is dimly, vaguely present, as if existing yet as if not.")
Similar views: Wang Bi: "yánxiééryóuchéngyányǒuxiéérjiànxíng。" ("If one wishes to call it nothing, yet things come into being through it. If one wishes to call it something, yet its form cannot be seen.")
Chapter 14 · Sentence 7: shìwèizhuàngzhīzhuàngzhīxiàngshìwèihuǎng

[Interpretation 2] Novel · Medium Confidence

Combination: A-zhuàngB-zhīA-zhuàngB-A-A-zhīA-xiàngB-A-huǎngA
Translation: This is a state without a definite condition, a symbol without a concrete thing — called the dimly visible (huǎnghū).
Analysis: "zhuàng" (zhuàng) takes the meaning of "state/condition," and "xiàng" (xiàng) takes the meaning of "symbol." The Tao has no determinate condition yet forms the foundation of all conditions; it has no concrete image yet becomes the symbol of all things. "Huǎnghū" is not chaotic ignorance but infinite possibility that transcends determinacy.
Similar views: Heshanggong: "yánxíngzhuàngérnéngwèiwànzuòxíngzhuàng。" ("The One has no form or shape, yet it can create form and shape for the ten thousand things.")

[Sentence 8] yíngzhījiànshǒusuízhījiànhòu。(Approach it and you cannot see its head; follow it and you cannot see its rear.)

Chapter 14 · Sentence 8: yíngzhījiànshǒusuízhījiànhòu

[Interpretation 1] Traditional · High Confidence

Combination: yíngA-shǒuA-suíA-hòuA
Translation: Approach it from the front and you cannot see its head; follow it from behind and you cannot see its tail.
Analysis: The most prevalent interpretation. The Tao has no beginning and no end, transcending space and time. Go toward it, and it has no front (one cannot tell where it comes from); follow after it, and it has no rear (one cannot tell where it goes). Heshanggong's commentary: "duāndài。" ("The One has neither beginning nor end; one cannot anticipate it.")
Similar views: Heshanggong: "duāndài。" ("The One has neither beginning nor end; one cannot anticipate it.") "yányǐngérkàn。" ("The One leaves no shadow or trace and cannot be observed.")
Chapter 14 · Sentence 8: yíngzhījiànshǒusuízhījiànhòu

[Interpretation 2] Traditional · High Confidence

Combination: yíngB-shǒuB-suíA-hòuB
Translation: Face it and you cannot see its beginning; follow it and you cannot see its end.
Analysis: "shǒu" (shǒu) takes the meaning of "beginning/origin," and "hòu" (hòu) takes the meaning of "end/conclusion." Understanding from the temporal dimension: the Tao has no starting point and no endpoint; it is eternally infinite. This interpretation transforms a spatial description (front and back) into a temporal philosophical reflection (beginning and end), linking it to the temporal theme of "zhízhīdào" (holding fast to the Tao of antiquity) in the following sentence.
Similar views: Echoes Chapter 25: "érgǎizhōuxíngérdài" ("It stands alone and does not change; it moves in a cycle and is never exhausted") in its theme of eternality.
Chapter 14 · Sentence 8: yíngzhījiànshǒusuízhījiànhòu

[Interpretation 3] Traditional · Medium Confidence

Combination: yíngA-shǒuA-suíA-hòuA
Translation: Welcome it and you cannot see its head; follow it and you cannot see its rear.
Analysis: Heshanggong interprets from the perspective of self-cultivation: the Tao cannot be obtained through active pursuit; it can only return naturally through "eliminating passions and removing desires." Both "welcoming" (yíng) and "following" (suí) are active behaviors, yet the Tao precisely cannot be attained through active pursuit. Heshanggong's commentary: "chúqíngguīzhī。" ("Eliminate passions and remove desires, and the One will naturally return to you.")
Similar views: Heshanggong: "chúqíngguīzhī。" ("Eliminate passions and remove desires, and the One will naturally return to you.")

[Sentence 9] zhízhīdàojīnzhīyǒu。(Hold fast to the Tao of antiquity to master the affairs of the present.)

Chapter 14 · Sentence 9: zhízhīdàojīnzhīyǒu

[Interpretation 1] Traditional · High Confidence

Combination: zhíA-A-dàoA-A-B-jīnA-yǒuA
Translation: Hold fast to the Tao that has existed since antiquity, and use it to govern the affairs of the present.
Analysis: The most prevalent interpretation. Although the Tao is ancient and eternal, it can be used to guide present reality. Wang Bi's commentary: "yǒuyǒushì。" ("'You' (yǒu) means 'the affairs at hand.'") The ancient Tao is not an outdated relic but a timeless eternal principle — precisely because it is "formless and nameless," it is not constrained by the changes of time. This sentence is the critical turning point in the chapter, shifting from abstract description (the Tao's imperceptibility) to practical application.
Similar views: Wang Bi: "suījīntóngshíyóuchéngzhìzhě。" ("Although past and present differ and times and customs change, there is nothing that does not proceed from this [Tao] to achieve good governance.")
Chapter 14 · Sentence 9: zhízhīdàojīnzhīyǒu

[Interpretation 2] Novel · Medium Confidence

Combination: zhíA-B-dàoA-B-C-jīnA-yǒuA
Translation: By grasping the eternal Tao, one can respond to all things and affairs of the present.
Analysis: "" (gǔ) takes the meaning of "eternal" (not specifically referring to the past, but transcending time), and "" (yù) takes the meaning of "to respond to/handle." This interpretation shifts the emphasis from "governing the state" to the individual — anyone who grasps the eternal Tao can calmly respond to all present affairs and changes.
Similar views: Heshanggong: "shèngrénzhíshǒudàoshēng。" ("The Sage holds fast to the ancient Tao and brings forth the One to master all things.")
Chapter 14 · Sentence 9: zhízhīdàojīnzhīyǒu

[Interpretation 3] Novel · Medium Confidence

Combination: zhíB-A-dàoB-A-A-jīnA-yǒuB
Translation: Follow the principles of antiquity to steer the "Being" (yǒu) of the present — the realm of existence.
Analysis: "zhí" (zhí) takes the meaning of "to follow/practice," "dào" (dào) takes the meaning of "principle/reason," and "yǒu" (yǒu) takes the ontological concept. "Being" (yǒu) is understood as a philosophical ontological concept — the totality of all existents in the phenomenal world. The Sage follows the ancient Tao to steer this phenomenal realm, using "Non-being" (, the essence of the Tao) to master "Being" (yǒu, the existence of all things).
Similar views: Echoes Chapter 1: "míngtiānzhīshǐyǒumíngwànzhī" ("The nameless is the beginning of Heaven and Earth; the named is the mother of the ten thousand things") in its relationship between Being and Non-being.

[Sentence 10] néngzhīshǐshìwèidào。(To be able to know the primordial beginning — this is called the thread of the Tao.)

Chapter 14 · Sentence 10: néngzhīshǐshìwèidào

[Interpretation 1] Traditional · High Confidence

Combination: zhīA-A-shǐA-dàoA-A
Translation: To be able to understand the primordial origin — this is called the guiding principle () of the Tao.
Analysis: The most prevalent interpretation. To be able to trace back to the primordial state of the cosmos is to grasp the fundamental law of the Tao. "Dao ji" (dào) means the essential outline of the Tao, the overarching principle that governs all knowledge and practice. Wang Bi's commentary: "xíngmíngzhěwànzhīzōng。" ("That which is without form or name is the ancestor of the ten thousand things.") "suīzàijīnzhīshǐ。" ("Therefore, even in the present one can know the primordial beginning.") Heshanggong's commentary: "rénnéngzhīshàngběnshǐyǒushìwèizhīdàogāng。" ("One who can know that in high antiquity the primordial beginning was the One — this is called knowing the guiding principle of the Tao.")
Similar views: Wang Bi: "xíngmíngzhěwànzhīzōng。" ("That which is without form or name is the ancestor of the ten thousand things.") Heshanggong: "rénnéngzhīshàngběnshǐyǒushìwèizhīdàogāng。" ("One who can know that in high antiquity the primordial beginning was the One — this is called knowing the guiding principle of the Tao.")
Chapter 14 · Sentence 10: néngzhīshǐshìwèidào

[Interpretation 2] Novel · Medium Confidence

Combination: zhīA-B-shǐB-dàoA-B
Translation: To be able to know the primordial source — this is called the thread () of the Tao.
Analysis: "shǐ" (gǔshǐ) takes the meaning of "primordial source," and "" (jì) takes its original meaning of "thread/clue" (the starting end of a silk thread). Although the Tao is "dimly visible" (huǎng) and "unnameable" (míng), there is still a "thread" () to be found — this thread is "the primordial source" (shǐ, the origin of all things). Seize the source, and you have seized the starting thread for understanding the Tao.
Similar views: Philological interpretations starting from the original meaning of "" (the starting end of a silk thread).
Chapter 14 · Sentence 10: néngzhīshǐshìwèidào

[Interpretation 3] Novel · Low Confidence

Combination: zhīB-A-shǐA-dàoA-A
Translation: To possess the wisdom to discern the ancient beginning — this is the guiding principle of the Tao.
Analysis: "zhī" (zhī) is read as interchangeable with "zhì" (zhì, wisdom). It is not ordinary "knowing" but a special form of wisdom needed to discern the primordial origin — this wisdom itself constitutes the guiding principle of the Tao. This interpretation implies that understanding "the ancient beginning" (shǐ) is not the accumulation of historical knowledge but a transcendent intuitive wisdom.
Similar views: Related to the philological tradition of reading "zhī" as interchangeable with "zhì" (wisdom).

Chapter Summary

This chapter contains 27 interpretation combinations.

[Core Divergences]

Chapter 14 is the most systematic passage in the Tao Te Ching describing the imperceptibility of the Tao. The chapter is elegantly structured: the first three sentences (seeing/hearing/grasping) establish the Tao's supra-sensory nature by negating sight, hearing, and touch; the middle section (merging into one → huǎnghū) uses paradoxical expressions such as "the form of the formless" and "the image of the thingless" to show that the Tao is neither substantial existence nor absolute nothingness, but exists in the "dimly visible" (huǎng) state between the two; the final two sentences (holding to the ancient Tao → the thread of the Tao) shift from cognition to practice — although the Tao is imperceptible, it can still be "held" (zhí) and "employed" (). Wang Bi's commentary reveals the core dialectic: "yánxiééryóuchéngyányǒuxiéérjiànxíng" — one cannot call the Tao "nothing," because all things come into being through it; one cannot call it "something," because its form cannot be seen. Heshanggong threads throughout a self-cultivation interpretation centered on "the One" (, an alias for the Tao): the Tao = the One, colorless, soundless, formless, and can only be apprehended through "receiving it in stillness, seeking it with spirit" (shòuzhījìngqiúzhīshén). Though the two commentarial paths differ, they point to the same conclusion: the method of knowing the Tao must transcend sensory analysis and return to a holistic intuitive grasp.
