Climate arriving in due season is peaceful; the correct transformation (Zheng Hua) follows Heaven's mandate and does not act recklessly. Excessive Qi overflows and arrives prematurely, insulting and punishing those that control it, while exploiting those it controls. Deficient Qi is urgent and arrives late; the element it controls acts recklessly, punishing the element it generates; the generated element suffers punishment and becomes diseased, and the element that controls it also exploits it.

[Note] "Arriving in due season" refers to the days and times when the Five Movements and Six Qi change. If the climate arrives exactly on these days and times, it is called "Correct Transformation and Balanced Qi" (Zheng Hua Ping Qi), obeying Heaven's command without reckless action. If the climate arrives before the season, with surplus Qi, it is termed "Excessive," named "Qi Yin" (Qi Overflow/Indulgence), which is also known as pathogenic transformation. "Punishing me" refers to the element that controls me; "I punish" refers to the element I control. For instance, if Wood Qi is excessive, Metal (which controls Wood) cannot restrain it; instead, Metal suffers Wood's insult. Consequently, Wood becomes prosperous, and Earth (controlled by Wood) must inevitably suffer suppression. In that year, Liver disease represents a direct pathogen (Zheng Xie), Lung disease represents a slight pathogen (Wei Xie), and Spleen disease represents a robbing pathogen (Zei Xie). The same logic applies to others. If the season has arrived but the climate has not, with deficient Qi, it is termed "Deficient," named "Qi Po" (Qi Urgency/Constraint), which is also pathogenic transformation. "What I control" refers to the element I overcome. "What generates me" refers to the element that produces me. "What I cannot control" refers to the element that controls me. For example, if Wood Qi is deficient, Earth (which I control) acts recklessly without fear, causing Water (which generates me) to become diseased; as Wood declines, Metal exploits this decline to punish Wood, causing disease. In that year, Kidney disease represents an excess pathogen (Shi Xie), Heart disease represents a deficiency pathogen (Xu Xie), and Lung disease represents a robbing pathogen (Zei Xie). The same logic applies to others. From this, one can deduce the principles of concurrent diseases involving two or three meridians.

When the movements and qi reach extremity (Kang), they all cause harm. Fearing the restraint of the offspring element, how dare one not accept it? Because there is acceptance and restraint, there is generation and transformation; if extreme without restraint, disease arises. After the victorious phase, the offspring avenges the mother, leading to recurrence; if suppressed and屈伏 (subdued), stagnation (Yu) forms disease. Stagnation erupts only when the offspring is weak, waiting for the proper time and position to inflict self-harm.

[Note] When the Five Movements and Six Qi are excessive to the extreme, it is called "Kang" (Extremity). Extremity inevitably harms the element it controls. For instance, if Wood reaches extremity, it inevitably harms Earth (its controlled element). The offspring of Earth, Metal, rises to restrain Wood. Wood fears accepting this restraint and dares not recklessly punish its mother (Wood itself in the context of the cycle, or rather, the text implies Wood's aggression towards Earth stops due to Metal's check). With this principle of acceptance and restraint among the Five Elements, harmony prevails, and generation/transformation occurs without disease. If Wood is excessively strong without restraint, it inevitably produces a "Victorious Disease" (Sheng Bing); the victim of the victorious disease is the Liver, and the suffering organ is the Spleen, resulting in concurrent disease of both meridians. Where there is victory, there must be revenge; where there is prosperity, there must be decline—this is the natural way. After Wood prospers, it must decline. The offspring of Earth, Metal, exploits Wood's decline to avenge its mother, thereby generating a "Revenge Disease" (Fu Bing); the organ of the revenge disease is the Lung, and the suffering organ is the Liver, resulting in concurrent disease of both meridians. The same applies to other organs. If Wood is deficient, it is suppressed by Metal, becoming subdued and unable to extend, giving rise to Wood Stagnation (Mu Yu) disease. However, the reason why stagnation erupts only after reaching extremity is that deficient Wood Qi cannot make the Fire element (its offspring) prosperous, thus it cannot take revenge. Therefore, it must wait until it attains its proper position/time to erupt. Although it erupts, it does not harm other organs but causes self-inflicted disaster/disease, due to the weakness of its own Qi. Thus, before eruption, it resembles the victorious disease: the victorious disease affects the Lung, and the stagnation disease affects the Liver. After eruption, it no longer affects the Lung but only affects the Liver. The same applies to other organs. The above text uses "excess" to explain "victory" and "deficiency" to explain "stagnation disease." This does not refer to the overall excess or deficiency of a single year, but rather indicates that when the governing Qi lacks victory, revenge, or stagnation dynamics.

All cases where excess recklessly harms others and causes disease are "Victorious Diseases" (Sheng Bing). Cases where the harmed offspring ultimately fails to take revenge, leading to stagnation and disease, are "Stagnation Diseases" (Yu Bing). Cases where deficiency leads to suppression and disease are also "Stagnation Diseases." Cases where one is stagnant, waiting for the offspring to avenge the mother, leading to disease, are "Revenge Diseases" (Fu Bing). By deducing from this, the rest can be understood.
