仁王護國般若波羅蜜多經疏 3.500

3.500

解曰：文中有五。言龍火者，礔礰起火。言鬼火者，能為疾疫。言人火者，世五通者遇現違緣，意願起火。言樹火者，亢陽過時，樹木起火。大火四起者，不善業熟，隨處火起。皆為難也。從此第四時候改變難。

Commentary: There are five items in the text. "Dragon fire" refers to fire arising from lightning and thunder. "Ghost fire" can cause pestilence. "Human fire" refers to worldly persons with five supernormal powers who, encountering adverse conditions in the present, ignite fire by their intention. "Tree fire" refers to excessive drought and heat causing trees to catch fire. "Great fires erupt on all sides" means that unwholesome karma has ripened, and fires break out everywhere. All of these constitute calamities. Next is the fourth [calamity], the calamity of unseasonable changes.
