sata-varsa hy anavrstir
bhavisyaty ulbana bhuvi
lokams trin pratapisyati
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As cosmic annihilation approaches, a terrible drought takes place on earth for one hundred years. For one hundred years the heat of the sun gradually increases, and its blazing heat begins to torment the three worlds.
