Next, one must also understand life and death.
By "life and death" we refer to the way of taking and letting go. 🌱
A dragon vein that stretches a thousand li ultimately converges upon a single plot of ground. If one cannot distinguish life from death as a basis for discernment, on what grounds can a choice be made?
The doctrine of life and death is not limited to a single standard. In broad terms: that which possesses qi is living; that which lacks qi is dead.
[Editor's note: It is incorrect to understand "living qi" (shēngqì) simply as the opposite of "dead qi" (sǐqì).]
Where the mountain vein is agile and vigorous, it is living; where it is rough, rigid, and stiff, it is dead.
[Marginal note: The claim that "rough and stiff equals death" is imprecise.]
When the dragon's momentum pushes leftward, the left is living and the right is dead; when the dragon's momentum pushes rightward, the right is living and the left is dead.
There is also the method of taking flesh amid thinness: withered and barren places are dead; moist and fleshy places are living. And the method of taking hunger amid satiety: places of hunger and lack are living; places of excessive fullness are dead.
And so on — these are matters the student must carefully investigate. What is living, take it; what is dead, discard it. Once taking and discarding are made clear, the method of locating the acupoint can be established; once the acupoint method is established, fortune and misfortune become manifest. If life and death are difficult to distinguish, and taking and discarding are not handled properly, one cannot claim to understand the transformative workings of nature.
[Editor's note: "Take the living, discard the dead" — this is common knowledge. The problem lies in not understanding what "taking hunger amid satiety" means — does it mean that once one has eaten one's fill, one will never eat again? This metaphor is far too strained.]
The central proposition of this chapter is: the essence of feng shui site selection is "distinguishing life from death in order to determine what to take and what to discard."
Though the dragon vein from a thousand li may be magnificent in momentum, what can actually be used is no more than "a single plot of ground." Faced with infinite possibilities within finite space, the geomancer must possess a set of judgment criteria — what constitutes life and what constitutes death — in order to precisely locate the acupoint.
The author presents multiple layers of criteria:
| Criterion | Living (Shēng) | Dead (Sǐ) |
|---|---|---|
| Presence or absence of qi | Has qi | Lacks qi |
| Form of the vein | Agile and lively | Rough and rigid |
| Direction of dragon momentum | The side it pushes toward | The side it pushes away from |
| Terrain fullness | "Taking flesh amid thinness" (moist places) | Withered and barren places |
| Terrain satiety | "Taking hunger amid satiety" (places of lack) | Excessively full places |
Notably, the two editorial notes within the original text constitute corrections and challenges to traditional formulations:
The significance of these three notes lies in the fact that they reveal a living tradition of scholarly critique. The commentator is not blindly annotating but engaging in dialogue with the original text, pointing out its logical flaws. This itself is a practice of the "life and death" worldview — not deferring to authority, daring to take and discard.
"Life and death" is ultimately a problem of effective resource allocation. While modern society no longer practices burial-site selection, this mode of thinking can be transferred to many domains:
The modern meaning of "taking hunger amid satiety" is not the literal "still hungry after eating one's fill," but rather: within a situation that appears complete and saturated, one must precisely seek the position of "lack" — because the place of lack is where vitality resides. Saturation implies rigidity; lack implies possibility. This idea aligns strikingly with the concept of "disruptive innovation" in contemporary innovation theory: when the mainstream market is "full," the real opportunity lies "hungry" in the neglected margins.
Regarding the critique that "rough and stiff equals death — this is incorrect," the modern perspective holds equally true: judging "life or death" cannot rely on surface appearance alone. A rough and stiff land vein may conceal deep vitality (such as hot springs atop granite geology), while an agile vein may be diffuse and rootless. This reminds us: any judgment criterion must be comprehensively weighed against specific circumstances — it cannot be applied dogmatically.
In contemporary decision-making, this chapter can be translated into a "Taking and Discarding Decision Checklist" :
Review method: After each decision, record the "life/death judgment basis" at the time, then revisit it after a period — did the judgment hold? Which criteria failed? This is practicing the ancients' thinking through a methodology of "hypothesis–action–review."
"Life and death" is on the surface a geomantic term, but it essentially engages a profound philosophical question: What constitutes the standard of "aliveness"?
The ancients took "having qi" as the criterion for life. Yet "qi" itself is a highly dialectical concept — it is formless and invisible, yet it can be indirectly apprehended through external features such as "pulse movement," "momentum," and "fullness of form." This resembles Laozi's principle that "being and non-being give rise to each other": life resides not in "being" itself, but in the transformation between "being" and "non-being."
"Taking flesh amid thinness" and "taking hunger amid satiety" further reveal a wisdom of counterintuitive thinking: vitality resides not in the extremes of a thing, but in the turning points of those extremes. Where thinness reaches its limit, there is the opportunity for flesh; where satiety reaches its limit, there is the demand of hunger. This is consistent with the thought in the I Ching that "when things reach their extremity, they change; when they change, they become unobstructed; when unobstructed, they endure."
The editorial note's challenge to "taking hunger amid satiety" also deserves attention. It reminds us that every analogy has its boundaries of applicability. The function of analogy is to illuminate, not to describe precisely. When an analogy is stretched too far, it ends up obscuring the truth. The absurd conclusion of "once full, one never eats again" precisely demonstrates that forcibly mapping a mundane metaphor onto an academic concept leads to logical dead ends. This self-awareness regarding the limits of language is itself a philosophical attitude.
