[I]t is preached in the Lotus Sūtra, fascicle 5, chapter 14 on the “Peaceful Practices”: “Various gods always protect the practicer for the sake of the dharma day and night.” This means that the great King of the Brahma Heaven, Indra, the sun and moon, the Four Heavenly Kings and others will never fail to protect those who say “Namu Myōhō Renge Kyō.”
Kangyō Hachiman-shō, Remonstration with Bodhisattva Hachiman
It is said that the merit of all the Buddhist scriptures (except the Lotus Sūtra) is found in the promise that men can become Buddhas after they have done good deeds, which means the attainment of Buddhahood is not certain. In the case of the Lotus Sūtra, however, when one touches it, one’s hands immediately become Buddhas, and when one chants it, one’s mouth instantly becomes a Buddha.
Ueno-dono Gozen Gohenji, Reply to My Lady, the Nun of Ueno
Is there anything which is brighter than the sun and the moon? Is there anything which is more pure than the lotus blossom? The Lotus Sutra is the sun and the moon and the lotus flower. Therefore, it is called the Sutra of the Lotus Flower of the Wonderful Law. I, Nichiren, am also like the sun and moon and the lotus flower.
Letter to the Wife of Shijō Kingo, Shijō Kingo Nyōbō Gosho
The Lotus Sūtra is named the “Wonderful Dharma” because it expounds that each of the Ten Realms mutually possesses the characteristics of the other nine realms, which means that all of the Ten Realms are equipped with the realm of Buddhas. In the mutual possession of the Ten Realms, each realm includes the other nine realms. As a result the Ten Realms have other Ten Realms, consisting of the hundred realms of all phenomena. The second fascicle of the Profound Meaning of the Lotus Sūtra says, “The one realm of all phenomena equipped with the other nine realms of all phenomena means the hundred realms of all phenomena.” It is not only in the Lotus Sūtra that the Ten Realms are mentioned. The cause and effect of the Ten Realms is revealed in the pre-Lotus sūtras as well. The reason why the Lotus Sūtra is regarded as the Wonderful Dharma is because the sūtra expounds the mutual possession of the cause and effect of the Ten Realms.
Ichidai Shōgyō Tai-I, Outline of All the Holy Teachings of the Buddha
Regarding the Chinese character “myō (wonderful),” the Lotus Sūtra states in chapter 10, “The Teacher of the Dharma,” that this sūtra opens the gate to the expedient teachings expounded in various sūtras and reveals the seal of the truth. Grand Master Chang-an interprets this in the “Preface” in the first fascicle of the Profound Meaning of the Lotus Sūtra that the Buddha opened up the door to the storehouse to disclose the valuables hoarded up in it, which was called myō. Grand Master Miao-lê further explains this in the first fascicle of his Commentary on the Profound Meaning of the Lotus Sūtra that to disclose means to open up. Contemplating on them, I should say, ” myō” means to “open up.”
Hokke Daimoku Shō, Treatise on the Daimoku of the Lotus Sūtra
You should consider that the Lotus Sūtra is like the king, parents, sun and moon, great ocean, Mt. Sumeru and heaven and earth while other sūtras are like regents, ministers, court nobles, or all the people in the country, various stars, rivers, mountains, trees and plants. We are the ignorant in the Latter Age of Degeneration committing sins and are not capable of accepting the Dharma. The king helps the people rather than his retainers; parents have compassion on their own children more so than unrelated persons; and the light of the sun and the moon is brighter than stars. Likewise, if the Lotus Sūtra is unsuitable to save the ignorant with inferior capacity in the Latter Age of Degeneration, you should realize there is no other sūtra.
Shō Hokke Daimoku-shō, Treastise on Chanting the Daimoku of the Lotus Sūtra
I received your letter, in which you said that you used to chant one chapter of the Lotus Sūtra each day, taking twenty-eight days to finish chanting it once; and that recently, however, you chant only the “Previous Life of the Medicine-King Bodhisattva” chapter each day. Then you asked: “Should I chant each chapter each day as I used to?”
You may chant the whole twenty-eight chapters, one chapter, one paragraph, one sentence or even one character of the Lotus Sūtra a day. Or, you may chant the daimoku, “Namu Myōhō Renge Kyō,” just once in a day or once in your whole life. Even if you may never chant the daimoku yourself, you may rejoice at hearing others chant it just once in your whole life. Or you may rejoice with others who rejoice at hearing a voice chanting the daimoku.
Gassui Gasho, A Letter on Menstruation, Nyonin Gosho
Of many illnesses, slandering the Lotus Sūtra is the most serious. Of many medicines, “Namu Myōhō Renge Kyō” is the most wonderful medicine.
Hokke Shuyō Shō, Treatise on the Essence of the Lotus Sūtra
Though my understanding of the sūtra is not profound, as I contemplate the spirit of the Lotus Sūtra and the Nirvana Sūtra, as well as their interpretations by T’ien-t’ai and Miao-lê, it seems to me that those who possess even the slightest belief in the Lotus Sūtra without holding any enmity against its teaching will not fall into the evil realms even if they commit evil deeds.
Shō Hokke Daimoku-shō, Treastise on Chanting the Daimoku of the Lotus Sūtra
You should know that the merit of the Lotus Sūtra is the same whether you chant the whole eight scrolls or just one scroll, one chapter, one stanza, one phrase, one character, or the daimoku. For instance, a drop of ocean water contains the water of numerous rivers, large and small, while a wish-fulfilling gem produces numerous treasures. In this sense, a drop of ocean water is the same as numerous drops and a gem is the same as numerous gems. One character of the Lotus Sutra is like this one drop of ocean water or one wishfulfilling gem. Numerous characters of the sutra are like numerous drops of ocean water or numerous wish -fulfilling gems.
