How does the mirror of the Lotus Sūtra reflect on those who put faith in the Lotus Sūtra during the Latter Age of Degeneration as stated in the sūtra? Śākyamuni Buddha unmistakably declares that they are the ones who made offering to ten trillion Buddhas in the past (in the “Teacher of the Dharma” chapter).
Concerned that ordinary people in the Latter Age of Degeneration might not believe in the words uttered by just one Buddha, the Buddha of Many Treasures in the Treasure Purity World to the east far away beyond many countries took the trouble of making a trip to this world in order to see Śākyamuni Buddha and testify that the Lotus Sūtra contains nothing but the truth.
Could there be any doubt unresolved after this? Nevertheless, perhaps because ordinary people in the Latter Age of Degeneration may not be wholly convinced, numerous Buddhas were summoned throughout the universe to stretch their long and wide tongues, which told nothing but the truth from incalculable kalpa (aeons) ago till today, upward high in the sky like Mt. Sumeru. This was indeed an event of great significance.
Therefore, if an ordinary person in the Latter Age of Degeneration believes in even one or two words of the Lotus Sūtra, it is equivalent to embracing the truth set forth by the tongues (dharmas) of Buddhas throughout the universe.
