仁王般若經疏 3.137

3.137

「大火燒國，萬姓燒盡。或鬼火、龍火、天火、山神火、人火、樹木火、賊火，如是變怪，亦讀說此經，為三難也。」

"Great fire burning the state, burning up the myriad common people; or ghost fire, dragon fire, heavenly fire, mountain spirit fire, human fire, tree fire, or bandit fire—when such strange portents occur, reading and reciting this sūtra also constitutes [the remedy for] the third calamity."
