In the presence of the Buddha of Many Treasures and the Buddhas manifested all over the universe, Śākyamuni Buddha clearly explained the difficulty of propagating the Lotus Sūtra in the Latter Age of Degeneration. In response, various bodhisattvas vowed: “Even if we are regularly abused, despised, and banished from our dwellings by those possessed by demons, we will endure all for the sake of propagating the Lotus Sūtra.” Also, it is preached in the Sūtra of the Golden Splendor, in which four Buddhas appeared in four directions verifying the truth of Śākyamuni Buddha’s teaching: “When evil men are respected and good men are punished, the country will be invaded and destroyed by foreign troops.” Consequently, no matter how they despise and mistreat Nichiren Shōnin, the words of Śākyamuni Buddha and the verification of them by the Buddha of Many Treasures and the Buddhas manifested all over the universe will endure, so that the Lotus Sūtra will surely spread.
