Because it is lamentable to see the possibility of our land and ourselves destroyed, I have determined to point this out even at the cost of my life. If the ruler of the land wishes to maintain peace, he should have begun to wonder and investigate what I have said. Believing in only the words of slanderers, on the contrary, he is persecuting me, Nichiren. The King of the Brahma Heaven, Indra, the sun, the moon, the Four Heavenly Kings, and the terrestrial gods, whose duty it is to protect the Lotus Sūtra, regarded slanderers of the True Dharma as outrageous in the past. However, when nobody pointed out such slanderers, these deities sometimes ignored them just as parents overlook the mischief of their sole child, although at other times they punished him with as little as a warning. Today, however, the ruler not only appoints slanderers of the True Dharma to official positions but also persecutes the man who happened to remonstrate him, not just for one or two days, one or two months, and one or two years, but for many years. Nichiren has been persecuted more severely than Never-Despising Bodhisattva, who was beaten with sticks and pieces of wood, and Monk Virtue Consciousness, who was about to be murdered, upholding the True Dharma in the past. Therefore, the King of the Brahma Heaven, Indra, the sun, the moon, the Four Heavenly Kings, the stars, and the terrestrial gods all are angry with the ruler and warn him often by sending strange phenomena in the sky and natural calamities on earth. Since he does not perceive their warnings and only intensifies the persecution of the man who remonstrates, they order the sagacious ruler of a neighboring land to chastise the ruler of Japan and send demons into his land to deceive the people and cause internal disruption.
Great events, regardless if they are good or bad, are foreshadowed by great omens. We saw the largest comet we have ever seen in 2,230 years or so since the death of the Buddha and experienced the severest earthquake we have ever had in history. They foretell the destruction of Japan, at the same time they are omens of the appearance of the true practicer of the Lotus Sūtra in Japan. There have been many sages endowed with wisdom and talent in China and Japan, but none has ever believed in the Lotus Sūtra as firmly as I, Nichiren, nor has anyone had as many strong enemies in the land as I do. From these facts, you should recognize Nichiren to be the prime practicer of the Lotus Sūtra in the world.
