“When the teachings of the Buddha truly become obscured and lost, then people will all let their beards, hair, and fingernails grow long, and the laws of the world will be forgotten and ignored. At that time, loud noises will sound in the air, and the earth will shake; everything in the world will begin to move as though it were a waterwheel. City walls will split and tumble, and all houses and dwellings will collapse. Roots, branches, leaves, petals, and fruits will lose their medicinal properties. With the exception of the heavens of purity, all the regions of the world of desire will become deprived of the seven flavors and the three kinds of vitality, until not a trace of them remains any more. All the good discourses that lead people to emancipation will at this time disappear. The flowers and fruits that grow in the earth will become few and will lose their flavor and sweetness. The wells, springs, and ponds will all go dry, the land everywhere will turn brackish and will crack open and warp into hillocks and gullies. All the mountains will be swept by fire, and the heavenly beings and dragons will no longer send down rain. The seedlings of the crops will all wither and die, all the living plants will perish, and even the weeds will cease to grow any more. Dust will rain down until all is darkness and the sun and moon no longer shed their light.
“All the four directions will be afflicted by drought, and evil omens will appear again and again. The ten evil acts will increase greatly, particularly greed, anger, and foolishness, and people will think no more of their fathers and mothers than does the roe deer. Living beings will decline in numbers, in longevity, physical strength, dignity, and enjoyment. They will become estranged from the delights of the human and heavenly realms, and all will fall into the paths of evil. The wicked rulers and monks who perform these ten evil acts will curse and destroy my correct teaching and make it difficult for those in the human and heavenly realms to stay there. At that time the benevolent deities and heavenly kings, who would ordinarily take pity on living beings, will abandon this impure and evil nation, and all will make their way to other regions.”
