The Definition of Feng Shui — Qi, Wind, and Water
氣乘風散,界水則止
Original Text 原文
氣乘風則散,界水則止。 古人聚之使不散,行之使有止,故謂之風水。 葬者,乘生氣也。
Translation 譯文
Qi rides the wind and scatters; it is retained at the boundary of water.
The ancients gathered it to prevent scattering; they directed it to make it stop.
Thus it is called Feng Shui (Wind-Water).
Burial means riding upon living Qi.
Key Concepts 核心概念
- 生氣 (Shēng Qì) — Living Qi
- The vital, generative Qi that flows through the earth and produces life, prosperity, and blessings for descendants. Distinguished from dead Qi (死氣), which produces decay and decline. The entire art of Feng Shui is the art of locating, capturing, and benefiting from living Qi.
- 乘風則散 (Chéng Fēng Zé Sàn)
- Qi rides the wind and scatters — wind (moving air) is the primary dispersant of Qi. A site exposed to prevailing winds loses its Qi no matter how good the underlying geological formations. Protection from wind is therefore a minimum requirement of any good site.
- 界水則止 (Jiè Shuǐ Zé Zhǐ)
- Qi is retained at the boundary of water — water acts as a boundary that stops Qi from flowing further. Where water embraces a site, Qi accumulates there. This is why water presence is the primary indicator of good Feng Shui.
Commentary 評注
This opening passage of the Zang Shu is the most famous and most quoted sentence in all of Feng Shui literature. In a single couplet, Guo Pu provides both the definition of Feng Shui as a discipline and its entire theoretical foundation.
The claim that Qi rides the wind and scatters is the origin of the term "Feng" (風 — wind) in Feng Shui. Wind represents all the dispersing forces that prevent Qi from accumulating: literal wind exposure, but also metaphorically the scattering effect of isolation, excessive openness, and lack of protective formations. The genius of the Zang Shu is to identify the problem first — Qi tends to scatter — and then define the entire practice as the solution.
The claim that Qi stops at the boundary of water is the origin of the term "Shui" (水 — water) in Feng Shui. Water marks the boundary of Qi accumulation. This is why classical Feng Shui sites — whether for burial or habitation — always have water in their foreground: the water literally marks the line where the descending mountain Qi stops, concentrates, and becomes accessible.
The definition of burial as "riding upon living Qi" (乘生氣) frames the entire practice of Yin House Feng Shui (陰宅風水) as a technical art, not a superstition. The question is precise: where does living Qi concentrate in this specific landscape? The answer requires reading landform, tracing mountain ridges (dragon veins), identifying water patterns, and locating the specific point where Qi naturally accumulates — the acupoint (穴).
