It is said in the Lotus Sūtra, fascicle 7 (chapter 23), “It will spread throughout the world in the fifth 500-year period after the death of the Buddha lest it should be lost.” It means that the Lotus Sūtra will spread in the period after the destruction of the pure dharma predicted in the Sūtra of the Great Assembly. The Lotus Sūtra also makes such references as : “those who uphold it in the evil world during the Latter Age of Degeneration” (fascicle 6: chapter 17); “at the time when the dharma is about to disappear in the future latter age” (fascicle 5: chapter 14): “even during the time of the Buddha much hatred and jealousy is raised against this Sūtra; how much more after His death!” (fascicle 4: chapter 10); and “much hate exists toward this Sūtra in the world, making it difficult to uphold it” (fascicle 5: chapter 14). Speaking of the fifth 500-year period after the death of the Buddha, namely, the period of increasing disagreements and quarrels, the Lotus Sūtra in its seventh fascicle (chapter 23) declares: “Devils, devils’ subjects, dragons, yakṣa demons, and kumbhāṇḍa devils will be trying to take advantage.” It is stated in the Sūtra of the Great Assembly: “Disputes and quarrels will arise within Buddhism itself.” And in the Lotus Sūtra, fascicle 5 (chapter 13): “Monks in the evil world will be cunning, flattering, and arrogant;” “some monks will live in monasteries and appear to be practicing the true ways;” and “devils will enter the bodies of those monks and cause them to abuse those who uphold the True Dharma.”
These citations meant to say that a large number of great monks will be haunted by a devil’s spirit all over the country in the fifth 500-year period. Suppose a wise man appears then. Those high priests haunted by a devil’s spirit would induce the king and his ministers and populace into speaking ill of him, abusing him, beating him with sticks or pieces of wood, throwing stones or tiles at him, and banishing or even executing him. Then Śākyamuni Buddha, the Buddha of Many Treasures and Buddhas in all the worlds in ten directions would order the great bodhisattvas appearing from underground, who in turn would order the King of the Brahma Heaven, Indra, the sun, the moon, and the Four Heavenly Kings to inflict strange phenomena in the sky and natural calamities on earth. If those kings do not heed the divine punishments, their neighboring countries would be ordered to chastise those evil kings and monks, resulting in the most terrible war the world has ever had.
Then all the people in the world living under the sun and moon, desirous of the welfare of their countries or of themselves, would pray in vain to all Buddhas and bodhisattvas. Finally, believing in the poor monk whom they have hated, an incalculable number of high priests, 80,000 great kings, and all the people would bow low with their heads touching the ground and holding their hands together in reverence, reciting “Namu Myōhō Renge Kyō.” It would be just as when the Buddha revealed the eighth of His ten supernatural powers in the “Divine Powers of the Buddha” of the (21st) chapter of the Lotus Sūtra that all the people without exception in all the worlds throughout the universe faced this Sahā World, resoundingly reciting in unison “Homage to Śākyamuni Buddha! Homage to Śākyamuni Buddha! Homage to the Lotus Sūtra! Homage to the Lotus Sūtra!”
