仁王護國般若波羅蜜多經疏 3.65

3.65

解曰：劫火洞然，明火災也。《瑜伽》第二說三大災，謂火、水、風相次起故。三中標初，此火災也。大千俱壞者，明一大千同成壞也。下之兩句，九山八海數各百億，滅無餘也。成住壞空相次而起，此明壞劫，餘三准知。《俱舍》十二、《瑜伽》第二皆廣說也。從此第二有情無常。

Exposition: 'The aeon-fire blazes fiercely' explains the calamity of fire. Fascicle two of the *Yogācārabhūmi* explains the three great calamities, which arise in succession as fire, water, and wind. Pointing to the first of the three, this is the fire calamity. 'The great trichiliocosm is destroyed together' clarifies that an entire great trichiliocosm is formed and destroyed together. The lower two lines mean that the nine mountains and eight oceans, each numbering one hundred billion, are destroyed without remainder. Formation, abiding, destruction, and emptiness arise in succession; this clarifies the aeon of destruction, and the other three may be inferred accordingly. Fascicle twelve of the *Abhidharmakośa* and fascicle two of the *Yogācārabhūmi* both explain this extensively. From here, the second part shows the impermanence of sentient beings.
