Except for bodhisattvas such as Superior Practice and Limitless Practice, highest-ranking leaders of the bodhisattvas who emerged from the earth, no one is allowed to appear in the 500-year period at the beginning of the Latter Age of Degeneration and to spread the five letters of myō, hō, ren, ge, and kyō, which is the substance of all existing things. Furthermore, no one else can form the Most Venerable One (honzon) with the two Buddhas, Śākyamuni and Many Treasures, seated side by side inside the Stupa of Treasures. This is because these (daimoku and honzon) are the gist of the “actual three thousand existences contained in one thought” doctrine expounded in the “Life Span of the Buddha” chapter in the essential section of the Lotus Sūtra, and it should be spread by bodhisattva disciples of the Original Buddha.
