俱舍論頌疏論本 12.40

12.40

釋曰：三災火水風者，此大三災逼有情類，令捨下地，集上天宮。初火災興由七日現，次水災起由雨霖霔，後風災生由風相擊。此三災力壞器世間，乃至極微亦無餘在。

The commentary explains: 'The three calamities are fire, water, and wind': these three major calamities press upon the classes of sentient beings, causing them to abandon the lower realms and gather in the upper celestial palaces. The calamity of fire first arises through the appearance of seven suns; the calamity of water next arises through pouring rain; the calamity of wind arises later through winds crashing against one another. The power of these three calamities destroys the physical world, so that not even an atom remains.
