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.

There are two ways of meditating on the doctrine of “3,000 existences contained in one thought.” One is the “theoretical” way, and the other is the “actual” way. Grand Masters T’ien-t’ai and Dengyō practiced the former. I, Nichiren, now practice the latter. As my method of practicing meditation is superior, difficulties befalling me are harder to bear. What T’ien-t’ai and Dengyō propagated was based on the doctrine of “3,000 existences contained in one thought” expounded in the theoretical section [of the Lotus Sūtra], while what I, Nichiren, propagate is based on the doctrine of “3,000 existences contained in one thought” in the essential section. The difference between the two is as great as the difference between heaven and earth. Remember this especially at the time of the last moment of life. Have an unwavering faith in the Lotus Sūtra and continue chanting the daimoku, which is the right way of meditation based on the “actual” doctrine of “3,000 existences contained in one thought. ”

Śākyamuni Buddha declared that, although the scriptures preached during the first forty years or so are as numerous as sands of the Ganges River, they did not reveal the truth, which would be explained in the Lotus Sūtra during the following eight years. At the moment the Buddha of Many Treasures emerged from the earth and attested it all to the truth. Then various Buddhas in manifestation (funjin) came crowding together from various worlds in the universe attesting it to be true and rejoicing by touching the Brahma Heaven with their long, wide tongues. The meaning of these words in the Lotus Sūtra is shiningly clear – brighter than the sun in the blue sky and the full moon at midnight. Look up and put your faith in it. Prostrate yourself before it and think hard about it.

In the Annotations on the Words and Phrases of the Lotus Sūtra, Miao-lê writes: “The single moment of understanding by faith is foremost of the practices in the essential section.” The first of the four depths of faith in the time when the sūtra was taught is the single moment of understanding by faith and the first of the five stages of practice after the Buddha’s passing away is the stage of rejoicing. Within these two can be found all 100 realms, 1,000 aspects, and 3,000 modes of existences as if in a treasure chest. They are the gate out of which all the Buddhas of all time and space emerge.

T’ien-t’ai’s interpretation makes it clear that even great bodhisattvas who have thoroughly studied Mahāyāna sūtras such as the Flower Garland Sūtra, Hōdō sūtras and the Wisdom Sūtra and reached the rank next only to the Buddha is incomparably inferior to those who merely listened to the Lotus Sūtra and had a connection with it, namely ordinary people in the Latter Age of Degeneration who were unable to eliminate the evil passions and master even one supernatural power.

On the palm of a man named Mahānāma a pebble changed to a precious stone. King Konzoku is said to have been able to transform sand into gold. The Lotus Sūtra enables even insentient beings such as grass and trees to attain Buddhahood, not to speak of sentient beings that possess minds such as humans. The Lotus Sūtra enables the Two Vehicles whose seed of Buddhahood has been burned to attain Buddhahood, how much more so with people whose seed of Buddhahood is still alive! Moreover, the Lotus Sūtra enables even the icchantika who has no religious belief to attain Buddhahood, how much more it will lead those with religious faith.

Once upon a time, a man who had offered a “rice cake” made from mud to a Buddha ascended the throne in a kingdom due to this virtuous act. As the Lotus Sūtra is the dharma superior to a Buddha, those who make donations to the sūtra will inevitably gain blessings in this life and attain Buddhahood in the future lives, will they not?
