Translation: If one wishes to contract something, one must first temporarily expand it.
Analysis: The most mainstream interpretation. This is a classic expression of Laozi's dialectics: to close, first open; let things reach their extreme, and the pendulum inevitably swings back, producing natural contraction. Wang Bi's commentary: "将欲除之，必固兴之" — "If one wishes to eliminate something, one must first let it flourish." Heshanggong's commentary is similar. This is the philosophical basis for the strategy of "letting the enemy advance in order to capture them."
Similar views: Wang Bi's commentary on this chapter as a whole: the principle that things reverse at their extremes, and that the soft and weak overcome the hard and strong.
Translation: If one wishes to seize something, one must first make it expand.
Analysis: Here 歙 takes the meaning of "seize/collect," and 张 is used causatively. This interpretation emphasizes the strategic level—to harvest something, first help it swell; when it reaches its peak, it can naturally be collected. This carries overtones of political statecraft.
Similar views: Han Feizi cited this chapter in discussing the arts of governance.
Translation: If one wishes to weaken something, one must first temporarily make it strong.
Analysis: Structurally identical to the preceding sentence. What reaches the peak of strength must inevitably decline—to make something weak, first let it become strong; when its strength reaches the extreme, weakness comes of itself. This is a natural law, not human manipulation. Heshanggong's commentary: "先强者后必弱也" — "That which is first strong must later become weak."
Similar views: Heshanggong: "先强者后必弱也" — "That which is first strong must later become weak."
Translation: If one wishes to abolish something, one must first temporarily make it flourish.
Analysis: The same dialectical pattern. When a thing flourishes to its extreme, it naturally moves toward decline and obsolescence. Heshanggong's commentary: "先兴者后必废也" — "That which first flourishes must later fall into disuse."
Similar views: Heshanggong: "先兴者后必废也" — "That which first flourishes must later fall into disuse."
Translation: If one wishes to take from something, one must first temporarily give to it.
Analysis: The culmination of the four parallel sentences. First give, then take—to seize, one must first bestow. Heshanggong's commentary: "先与者后必夺也" — "That which is first given must later be taken away." These four sentences reveal the dialectical law of development: expansion pushed to the extreme leads to contraction; strength pushed to the extreme leads to weakness; flourishing pushed to the extreme leads to abolition; giving pushed to the extreme leads to loss.
Similar views: Heshanggong: "先与者后必夺也" — "That which is first given must later be taken away."
Translation: This is called subtle wisdom.
Analysis: "Subtle illumination" (微明)—a refined perceptiveness. The ability to discern the law by which things pass from flourishing to decline and reverse at their extremes constitutes "subtle illumination." This wisdom is not obvious; it is hidden and exquisite—requiring profound insight to grasp. Heshanggong's commentary: "此三事者天地所为，道之所行，人君宜知之" — "These three matters are the workings of Heaven and Earth, the operations of the Tao (道); rulers should understand them."
Similar views: Resonates with Chapter 52 of the Laozi: "见小曰明" — "To perceive the small is called illumination."
Translation: This is called insight within the imperceptible.
Analysis: Here 微 takes the meaning of "imperceptible/hidden," and 明 takes the meaning of "insight/discernment." To be able to discern the direction of things while they are still in their imperceptible, nascent stage—this is true wisdom. It is like seeing the inevitability of contraction at the very beginning of expansion, and foreseeing the outcome of weakness at the height of strength.
Similar views: Connected to the concept of "knowing the incipient" (知几).
Translation: The soft and weak can overcome the hard and strong.
Analysis: One of the core propositions of Laozi's philosophy. Derived from the four dialectical pairs above: that which is hard and strong, pushed to the extreme, must inevitably decay, while that which is soft and weak, not yet having reached the extreme, can endure. This is the philosophy of water—water is supremely soft yet can wear through stone. Wang Bi's commentary: "柔弱同通，不可穷极" — "The soft and weak are pervasive in their reach and cannot be exhausted."
Similar views: Wang Bi: "柔弱同通，不可穷极" — "The soft and weak are pervasive and cannot be exhausted." Resonates with Chapter 78: "天下莫柔弱于水" — "Nothing in the world is softer or weaker than water."
Translation: Fish must not leave the deep pool; the state's instruments of governance must not be displayed to others.
Analysis: The most mainstream interpretation. A fish that leaves the deep will die—the deep is the fish's foundation; likewise, the instruments of governance must not be lightly revealed, lest they be exploited. Heshanggong's commentary: "利器者，谓权道也。治国之利器，不可以示执事之臣也" — "The 'sharp instruments' refer to the arts of power. The sharp instruments of governance must not be shown to the ministers who carry out affairs." Wang Bi's understanding is similar. This sentence warns rulers to keep their capabilities deeply concealed.
Similar views: Heshanggong: "利器者，谓权道也。不可以示执事之臣也" — "The 'sharp instruments' refer to the arts of power. They must not be shown to the ministers who carry out affairs."
Translation: Fish must not leave the depths; the state's sharp weapons must not be flaunted before others.
Analysis: Here 渊 takes the meaning of "the depths" (a metaphor for one's foundation), 利器 retains its literal meaning of "sharp weapons," and 示 takes the meaning of "flaunt." The Sage (圣人) is like a fish—one must remain in the depths (maintaining gravity and stillness) and must not be frivolous or exposed. A state's military might should likewise not be flaunted or brandished, lest it invite disaster.
Similar views: Consistent with this chapter's principle that "the soft and weak overcome the hard and strong"—concealing one's depths is the way of softness and weakness.

[Core Divergences]
Chapter Thirty-Six is the most concentrated expression of Laozi's dialectics and one of the most debated chapters in history. The first four sentences, in strict parallelism, reveal the cosmic law that things reverse at their extremes: if one wishes to contract, one must first expand; if one wishes to weaken, one must first strengthen; if one wishes to abolish, one must first let flourish; if one wishes to take, one must first give. Laozi calls this insight "subtle illumination" (微明)—the delicate wisdom of perceiving the direction of things at their inception. "The soft and weak overcome the hard and strong" is the chapter's central proposition and one of the most famous theses of the Tao Te Ching. The chapter concludes with "Fish must not leave the deep; the state's sharp instruments must not be displayed to others": true power lies not in displays of strength but in deep concealment. Because its description of dialectical laws closely approaches political realpolitik, this chapter has historically prompted divergent interpretations—is it naïve observation of natural philosophy, or the deliberate application of political wisdom? This divergence runs throughout the entire commentarial tradition of the Tao Te Ching.
