Then treatment can be effective; ("Ping" [flat/peaceful] means quiet. "Mi" [secret/tight] means firm or consolidated. What human life relies upon is only Jing [Essence] and Shen [Spirit]. Jing is generated by Yin, and Shen transforms through Yang. Therefore, when Yin is peaceful and Yang is consolidated, the Spirit and Essence are regulated.) If Yin and Yang separate and break apart, Jing Qi [Essence and Vital Energy] will cease. ("Jue" [decide/sever] and "Jue" [cut off/extinguish] mean the same. Having Yang without Yin leads to the exhaustion of Jing; having Yin without Yang leads to the exhaustion of Qi. The mutual separation and rupture of the two implies either illness or death, which precisely demonstrates that Yin and Yang cannot be neglected.) Due to exposure to wind, chills and fever arise. (The preceding text discussed Wind Malaria [Feng Nüe] and Wind pathogen lodging to disrupt Zheng Qi [Upright Energy], but did not fully elucidate the nature of Wind. Thus, it reiterates this point and extends to the pathogens of the four seasons. Being exposed to wind allows Cold pathogen to invade externally while Yang Qi resists internally; Yin and Yang press against each other in conflict, thus generating chills and fever.) Injury by Wind in Spring, with pathogenic factors lingering, results in severe diarrhea; (Injury by Wind in Spring indicates an excess of Wood pathogen. After lingering for a long time, it overacts on Spleen Earth, thus causing severe diarrhea.) Injury by Summerheat in Summer, leading to Malaria [Nüe] in Autumn; (Injury by Summerheat pathogen in Summer, if not manifesting as immediate illness...)
