虚甚则散,涣漫不收。有边无中,其名曰芤。
浮小为濡,绵浮水面。(绵一作帛。)濡甚则微,不任寻按。

泛泛欲上之势,如水中漂木,虽按之使沉,亦必随手而起,《脉经》所谓举之有余,

The floating pulse (Fumai, Floating Pulse) models Heaven; it can be felt with light pressure. It floats superficially, like wood drifting on water.
If the floating pulse is forceful and surging (Hongmai, Surging Pulse), the arrival is vigorous while the departure is leisurely. If it is weak and deficient in size, it is slow and soft.
When deficiency is extreme, it becomes a Scattered pulse (Sanmai, Scattered Pulse), dissipating and loose without gathering. When there is palpation at the edges but emptiness in the center, it is named the Knotted pulse (Koumai, Knotted Pulse).
Floating and small is the Soggy pulse (Rumai, Soggy Pulse), like silk floating on water. ("Mian" is alternatively written as "Bo".) When the Soggy pulse is extreme, it becomes the Micro pulse (Weimai, Micro Pulse), which cannot withstand searching with heavy pressure.
Heaven covers from above; this is Yang. The floating pulse resembles this, hence it is said to model Heaven. Its position responds at the level of skin and hair, accessible with light touch. Upon pressing, there remains a tendency to float upward, like wood drifting in water; even if pressed down to sink, it rises immediately upon release. This corresponds to what the *Mai Jing* (Classic of Pulse Diagnosis) describes as "abundant when lifted, insufficient when pressed." If the floating pulse is accompanied by surging and large qualities, with vigorous arrival and leisurely departure, it is a forceful floating pulse, also called a Large-floating pulse. If the floating pulse is accompanied by deficient largeness, being slow and soft, it is a weak floating pulse, also called a Deficient-large pulse. If the floating and deficient-large quality becomes extreme, it dissipates and spreads, lacking consolidation and solidity, named the Scattered pulse. This corresponds to the *Mai Jing*'s description: "Qi is excess, Blood is deficient; there is exterior but no interior." If there is palpation on all four sides but emptiness in the center, it is named the Knotted pulse. "Kou" refers to hollow grass, shaped like a scallion stalk. This corresponds to the *Mai Jing*: "Floating, large, and soft; empty in the center when pressed, solid on both sides." If it is floating and small, it is named the Soggy pulse. Like silk floating on water, it feels soft and thin upon pressure, completely lacking force. If the floating and soggy quality becomes extreme, it becomes extremely deficient and extremely small, named the Micro pulse. It cannot bear heavy searching pressure. This corresponds to the *Mai Jing*: "As if present or absent, or nearly disappearing."
The Deep pulse (Chenmai, Deep Pulse) models Earth, lying close to tendons and bones. It lies deeply within; when sinking to the extreme, it becomes the Hidden pulse (Fumai, Hidden Pulse).
If deep and forceful, it is the Firm pulse (Laomai, Firm Pulse): solid, large, wiry, and long. When the Firm pulse is extreme, it becomes the Solid pulse (Shimai, Solid Pulse), hard and strong.
If deep and weak, it is the Weak pulse (Ruomai, Weak Pulse): soft and small like cotton. When the Weak pulse is extreme, it becomes the Fine pulse (Ximai, Fine Pulse), like a spider's thread.
Earth carries from below; this is Yin. The deep pulse resembles this, hence it is said to model Earth. Its position is near the tendons and bones, obtainable only with heavy pressure, possessing a deeply sinking tendency. This corresponds to the *Mai Jing*: "Insufficient when lifted, abundant when pressed." If it sinks to the extreme, appearing attached to tendons and bones, it is named the Hidden pulse. This corresponds to the *Mai Jing*: "Obtainable only with extreme heavy pressure." If it is deep and forceful, presenting as solid, large, wiry, and long: "Wiry" implies tension and urgency; being large and solid implies firmness and stability, the meaning of which can be inferred. The *Mai Jing* mentions the Drum-taut pulse (Gemai, Drum-taut Pulse) but not the Firm pulse; one must know that the Firm pulse is essentially the Drum-taut pulse. The Drum-taut pulse feels like pressing a drumhead, also implying tension, urgency, and firmness, representing excess on the exterior. If the Firm pulse becomes extreme, both interior and exterior are solid, hard and strong, like having a root. If it is deep and weak, being small and soft, it is named the Weak pulse. This corresponds to the *Mai Jing*: "Extremely soft, deep, and fine; upon pressing, it seems to disappear under the fingers." When the Weak pulse becomes extreme, it becomes even softer and smaller, as if present or absent, lingering like a spider's thread, named the Fine pulse. It is not far removed from the Micro pulse.
