[T]he eleventh chapter of the Lotus Sūtra, “Appearance of the Stupa of Treasures,” states: “Those who uphold the teaching of this sūtra are deemed to serve Me, Śākyamuni, and the Buddha of Many Treasures. They also serve Buddhas in manifestation here who adorn and glorify their respective worlds.” This means that Śākyamuni Buddha, the Buddha of Many Treasures, and all the Buddhas in manifestation are in our minds, and that we, upholders of the Lotus Sūtra, will follow their steps and inherit all the merits of those Buddhas.
This is the meaning of the passage in the tenth chapter of the Lotus Sūtra, “The Teacher of the Dharma,” which reads: “Those who hear of this Lotus Sūtra even for a moment, will instantly attain Perfect Enlightenment.”
