佛說仁王般若波羅蜜經 2.39

2.39

“Great King! The realm I now transform comprises ten billion Mount Sumerus and ten billion suns and moons, and each Mount Sumeru has four continents. In this southern Jambudvīpa, there are sixteen great states, five hundred medium states, and ten thousand small states. In these states there are seven calamities; when all the kings, on account of these calamities, expound and read the prajñāpāramitā, the seven calamities will instantly be extinguished, the seven blessings will instantly arise, the myriad common folk will be peaceful and happy, and emperors and kings will rejoice.
