Question: Why is it that some illnesses are resolved through sweating after a battle? Answer: When the pulse is floating and tight, but upon pressing it feels hollow, this indicates a fundamental deficiency. Therefore, sweating after a battle is expected. The person is fundamentally deficient, hence the battle occurs; because the pulse is floating, sweating is expected to resolve the illness. If the pulse is floating and rapid, and upon pressing it does not feel hollow, this person is not fundamentally deficient. If they wish to resolve the illness on their own, they will only sweat, without engaging in a battle. Question: Why is it that some illnesses are resolved without a battle and through sweating? Answer: When the pulse is large, floating, and rapid, it is understood that the illness will be resolved through sweating without a battle. Question: Why is it that some illnesses are resolved without a battle or sweating? Answer: The pulse naturally becomes faint, indicating that there has been previous sweating, vomiting, purging, or loss of blood, leading to a lack of body fluids internally. This results in the spontaneous harmonization of yin and yang, and the illness will resolve on its own without a battle or sweating.

• A floating and tight pulse indicates an excess of pathogenic factors; pressing it and finding it hollow indicates a deficiency of vital energy. When vital energy is deficient and pathogenic factors are in excess, the struggle between them causes sweating after a battle, resolving the illness.
• A floating and rapid pulse indicates that the pathogenic factors are not in excess; pressing it and finding it not hollow indicates that the vital energy is not deficient. When vital energy is not deficient and pathogenic factors are not in excess, the pathogenic factors cannot struggle with the vital energy, hence the illness is resolved through sweating without a battle.
• If the pulse is not hollow, it is understood that there will be no battle; if the pulse is not floating, it is understood that there will be no sweating; if the pulse naturally becomes faint, it is understood that there has been previous sweating, vomiting, purging, or loss of blood. Due to the lack of body fluids internally, both pathogenic factors and vital energy decline, leading to the spontaneous harmonization of yin and yang, hence the illness is resolved without a battle or sweating.
