A respiration cycle with six pulses is slightly rapid, termed *Shu Mai* (Rapid Pulse). Only children are uniquely at ease (Children consider six beats per respiration as a normal pulse; anything else indicates Fire.) Floating, sinking, solid, rapid, scattered, and clear (Floating and rapid with force indicates Excess Fire in the exterior, suitable for dispersing; Sinking and rapid with force indicates Excess Fire in the interior, suitable for clearing.) Weakness indicates deficiency, requiring tonifying herbs (Rapid but weak indicates Deficient Fire, suitable for tonifying Qi or benefiting the origin of Fire.) The Cun position indicates pain in the throat and tongue, vomiting, coughing, irritability, and thirst (The stomach opening corresponds to the heart center, also governed by the Cun position. Stomach Fire causes vomiting; Fire forcing the Lung causes coughing and irritability; Lung Metal being scorched causes thirst.) The Guan position relates to digestion and easy hunger (Stomach having excess leads to consuming food easily and feeling hungry quickly.) The Chi position indicates aversion to cold and strangury (The *Mai Jing* states that a rapid Chi pulse indicates aversion to cold and yellow-red urine. It also says a rapid Shaoyin pulse in men indicates Qi Strangury. Since the Kidney is Yin and belongs to Water, Yin deficiency allows Yang to converge, causing internal heat and thus external aversion to cold. Fire hidden in water causes yellow-red urine. In severe cases, Bladder Qi fails to transform, leading to difficult urination, pain, and strangury.)
(The *Mai Jing* records Bian Que's words: A pulse that has an exterior but no interior portends death. The classic calls this *Jie Mai* (Knotted Pulse). What is Jie? Under the fingers, it feels like moving hemp seeds. Pressing lightly makes it scatter chaotically; pressing heavily makes it disappear. Thus, it is said to have an exterior but no interior, indicating Kidney exhaustion. This differs from the Knotted Pulse characterized by occasional pauses.)
Occasional pauses are called *Jie Mai* (Knotted Pulse). Yin excess and Yang deficiency cause Qi and Blood stagnation (Qi warms and moves Blood. Qi deficiency fails to warm Blood, causing Blood Cold; Qi deficiency fails to move Blood, causing Blood Stasis. Cold and Stagnant Blood forms knots; when Blood knots, Qi also knots.) Floating indicates painful accumulations attacking from the exterior. Sinking indicates painful accumulations pressing from the interior.
A rapid pulse with occasional pauses is called *Cu Mai* (Hasty Pulse). Yang is excessive, Yin is insufficient, Phlegm-Fire cauterizes, leading to wheezing/coughing or macules/toxins (Internal red-purple abundance constitutes macules. Black macules are hard to treat. Carbuncles and sores are all toxins.)
Movement stops midway and cannot return immediately. If the pause has a constant rhythm, it is named *Dai Mai* (Intermittent Pulse). This is not necessarily frequent palpitations due to Taiyang Disease. It may involve abdominal pain, diarrhea, and dysentery causing harm. Chronic illness is indeed ominous (Bian Que said: A pulse stopping once after five beats, without further change, or once after seven beats, without further change, is named Dai Mai in the classics, portending death.) Even in healthy people, it indicates organ failure (*Ling Shu* states: One day consists of fifty circuits of Ying Qi, nourishing the essence of the Five Zang organs. To count these fifty circuits, hold the pulse point and count the beats. Fifty beats without a Dai pulse mean all Five Zang organs receive Qi. Forty beats with one Dai pulse mean one Zang lacks Qi. Thirty beats with one Dai pulse mean two Zangs lack Qi. Twenty beats with one Dai pulse mean three Zangs lack Qi. Ten beats with one Dai pulse mean five Zangs lack Qi, granting a short lifespan. According to the *Mai Jing*, forty beats with one stop indicate death within four years; thirty beats with one stop, three years; twenty beats, two years; ten beats, within one year; five beats, within five days. This is a general statement and should not be applied rigidly.) In women, during pregnancy beyond three months, seeing this pulse is not an obstruction (Old texts state that at three months of pregnancy, the pulse is Dai. However, Dai pulses can occur at five or seven months. It should be assessed at both Chi positions. For example, nine beats followed by one pause, returning after a long time, or nine to ten beats with one pause, returning after a long time—this is what is meant by "constant number." Again, nine to ten beats without pause, or twelve to fifteen beats with one pause, as long as there is a constant number, it is a Dai pulse. The constant pause of Dai reflects trustfulness (Xin), which Earth governs. This is the arrival of Spleen-Stomach Qi. It emerges as the vital Qi of all things. The Spleen and Stomach are the vital Qi of the Five Zang organs. When vital Qi arrives, pregnancy occurs. Heaven generates Water first, then Fire, Wood, Metal, and Earth, completing the Five Elements. The initial formation of the fetus is Heavenly One Water. Then Fire, Wood, Metal, and Earth generate, making the Qi of the Five Zang organs complete. With complete Zang Qi, the pulse becomes Dai. Why is Dai considered a death pulse? From the perspective of generation numbers, complete Zang Qi corresponds to the number of Earth generating five, hence the pulse is Dai. From a superficial view, after form is established, Ying and Wei Qi circulate with heaven and earth fluids without any pause per breath. If the Five Zangs lack Qi but only Stomach Qi remains, the pulse is still Dai. However, this Stomach Qi is like a lamp running out of oil, so death will soon follow.)
Pulses are distinguished not by floating/sinking or rate, but by shape. *Xian Mai* (Wiry Pulse) is straight and long, like pressing a bowstring. *Jin Mai* (Tight Pulse) is forceful in both directions, snapping against the hand like a turning rope. *Chang Mai* (Long Pulse) extends far and naturally, like the tip of a raised pole. *Duan Mai* (Short Pulse) does not fill the position, shrinking at both ends. *Xi Mai* (Fine/Thready Pulse) is straight and responds to the finger like a silk thread. *Se Mai* (Choppy Pulse) is fine and difficult to flow, responding like a light knife scraping bamboo. *Hua Mai* (Slippery Pulse) moves forward and backward, smooth like pearls. *Dong Mai* (Moving Pulse) is large like a bean, quivering and shaking. These are eight pulses.
