The pulse can be excessive, deficient, yin-yang multiplied, overflowing, submerged, obstructed, or blocked. What does this mean? Well: before the gate, it is the movement of yang, and the pulse should appear nine parts and floating.

• If it exceeds, it is called excessive;
• if it is reduced, it is called deficient;
• if it rises to the fish border, it is called overflowing, which is Waiguan (TE5) internal obstruction, and this is the pulse of yin multiplying.

• If it exceeds, it is called excessive;
• if it is reduced, it is called deficient;
• if it sinks into the chi, it is called submerged, which is Neiguan (PC6) external obstruction, and this is the pulse of yang multiplying.

bubble_chart Note

1. Excessive and deficient are disease pulses. Anuria and vomiting, submerged and overflowing, are death pulses.
2. The theory of anuria and vomiting, Suwen-Liujie Cangxiang Lun and Lingshu Chapter 9 and Chapter 49, both dominant qi at Renying (ST9), as yang meridians are determined by Renying (ST9), and yin meridians are determined by the qi opening. Now, Yue Ren uses the front and back of the gate to speak, taking the inch as yang and the chi as yin.
3. The front of the gate is yang, the position where the inch moves, and the pulse appears nine parts and floating. Nine is the yang number, and the inch position is floating, so the yang pulse is its normal state. Excessive means exceeding the original position, exceeding the normal pulse, and deficient means deficient in the original position, deficient in the normal pulse, both are disease pulses.
4. Sui means to go straight ahead without turning back. Xie's theory of sui means straight up and down, with no intention of turning back, which is meaningful.
5. The classic says: when yin qi is too strong, yang qi cannot interact with it. Because yang qi cannot interact with yin, yin rises and overflows at Yuji (LU10), which is Waiguan (TE5) internal obstruction. Waiguan (TE5) internal obstruction means yang is closed externally and does not descend, while yin follows and emerges internally to block it. This is the pulse of yin multiplying yang.
6. After the gate is yin, the position where the chi pulse moves, and the pulse appears one inch and sinking. One inch is the yin number, and the chi position is sinking, so the yin pulse is its normal state. Excessive means exceeding the original position, exceeding the normal pulse, and deficient means deficient in the original position, deficient in the normal pulse, both are disease pulses.
7. The classic says: when yang qi is too strong, yin qi cannot interact with it. Because yin qi cannot interact with yang, yang sinks and submerges at the chi, which is Neiguan (PC6) external obstruction. Neiguan (PC6) external obstruction means yin is closed internally and does not ascend, while yang follows and enters externally to block it. This is the pulse of yang multiplying yin.
8. Submerged is like something being submerged, falling from above to below. Overflowing is like water overflowing, emerging from inside to outside. The submerged and overflowing pulses are the diagnosis of solitary yin Duyin, separated above and below, so it is called the true visceral pulse, meaning there is no stomach qi to harmonize it. Anyone who gets this pulse will die even without illness.
9. This chapter discusses the excessive and deficient of yin-yang, which are disease pulses but not yet critical. If it rises to the fish border or sinks into the chi, becoming submerged or overflowing, then it is a death pulse. The word sui here is crucial, as it connects the previous and following key points. Otherwise, excessive, deficient, yin-yang multiplied, anuria and vomiting, submerged and overflowing would all be mixed into one meaning without distinction.
10. Someone asked about the difference between the yin-yang multiplied in this chapter and the theory in Chapter 20. It is said: this chapter is about the extreme of yin-yang multiplied leading to submerged and overflowing, while Chapter 20 is about yin-yang alternately multiplied and hidden. The difference between the powder on a quarter of a coin in Chapter 20 and the word sui in this chapter is significant. Geng means alternately, while sui means directly. Submerged and overflowing are death pulses, while hidden is a disease pulse, so they cannot be discussed in the same context.
