[A letter of explanation written by Nichiren Shōnin on behalf of Shijō Yorimoto on the 25th of the sixth month in the third year of the Kenji Period (1277) and submitted to the lord of the Ema Family.]

“Master Shan-tao of the Pure Land Sect in China said that ten out of ten or 100 out of 100 of those who practice the nembutsu will be able to be reborn in the Pure Land through the power of the original vow of Amitābha Buddha, but not even one out of one thousand persons who practice the holy way gate such as the Lotus Sūtra will be able to attain Buddhahood. Priest Hōnen of the Pure Land Sect in Japan urged his followers to abandon, close, set aside, and cast away the Lotus Sūtra, the holy way gate, calling the practicers of the holy way gate a school of bandits. Zen Sect insists that Śākyamuni Buddha’s enlightenment is transmitted to practicers only through the mind (special transmission without scriptures or preachings) and therefore sūtras are needless.

“The Buddha Śākyamuni, however, states in the Lotus Sūtra: ‘I will reveal the Truth after an extensive period of preaching.’ The Buddha of Many Treasures also verified that ‘The Sūtra of the Lotus Flower of the Wonderful Dharma is entirely true,’ and the Buddhas manifested in the worlds throughout the universe also testify to the truth of the Lotus Sūtra. Which should we believe between the two: Śākyamuni Buddha, the Buddha of Many Treasures and the Buddhas manifested in the worlds throughout the universe who prove the truth of the Lotus Sūtra, or Grand Master Kōbō of Japan who says that the Lotus Sūtra is a sūtra of no merit? Śākyamuni Buddha, the Buddha of Many Treasures, and the Buddhas manifested in the worlds throughout the universe preach that all without exception will attain Buddhahood through the Lotus Sūtra, but Master Shan-tao and Priest Hōnen said that no one could attain Buddhahood through the Lotus Sūtra, which we should abandon, close, set aside, and cast away. The teachings of Śākyamuni Buddha, the Buddha of Many Treasures, and the Buddhas in manifestation and those uttered by Master Shan-tao and Priest Hōnen are as different as fire and water or clouds and mud. Which should we put faith in? Which should we discard? …

To this question put forth by Sammi-kō, Ryūzō-bō replied: “How can I have any doubts about such senior masters as Shan-tao and Hōnen? The only thing that ordinary monks like myself can do is to pay respect and venerate them.”

Then, Sammi-kō asked again: “Such an answer does not sound like your teaching. Although everybody respects their senior masters or men of virtue, it is willed in the Nirvana Sūtra, preached last by the Buddha, ‘Rely on the dharma, not on masters.’ This means that since masters may have made mistakes, one should depend upon the sūtras the Buddha expounded.
