"At the present time, numerous prayers are offered for the peace and safety of the nation. And yet in the first year of the Shōka era there was a severe earthquake, and in the second year of the same era, torrential rains and violent winds occurred and the rice plants failed to ripen. It would appear to me that there is some evil teaching in this country that is bringing about the destruction of the nation."

Nichiren is connecting Japan's natural disasters to spiritual causes. He's arguing that when people follow incorrect Buddhist teachings, it creates negative effects that manifest in the physical world as earthquakes, storms, and famines. This isn't superstition to him—it's the law of cause and effect operating on a societal level.

"In the Immeasurable Meanings Sutra it is stated: 'But in these more than forty years, I have not yet revealed the truth.' If we find no statements that invalidate this passage, then we should put no faith in what others say about right and wrong."

Nichiren is using the Buddha's own words to establish a hierarchy of teachings. He's saying that according to this sutra, all of Buddha's teachings for over 40 years were preparatory—not the ultimate truth. This passage becomes his key evidence that only the Lotus Sutra represents Buddha's final, complete teaching.

"Some years ago there appeared an eminent priest of erroneous wisdom who, for the sake of the ignorant people of this latter age, cast aside all the doctrinal principles and wrote a work entitled The Nembutsu Chosen above All."

This is Nichiren's pointed criticism of Honen, founder of Pure Land Buddhism in Japan. He's arguing that Honen's approach of focusing solely on chanting Amida Buddha's name actually abandons the complete path to enlightenment. Nichiren sees this as spiritual malpractice that cuts people off from their Buddha nature.

"I have relied solely on the sutras and treatises in determining what is correct and what erroneous, and on the pronouncements of the Buddha in making clear what is trustworthy and what is slanderous. I have not ventured to put forth any private theories of my own."

Nichiren is establishing his scholarly credibility and methodology. He's saying his arguments aren't based on personal opinion but on careful study of Buddhist scriptures. This reflects his confidence that an honest examination of the texts will support his conclusions about the Lotus Sutra's supremacy.

"After I have passed into extinction, in the last five-hundred-year period you must spread it [the Lotus Sutra] abroad widely throughout Jambudvīpa and never allow it to be cut off."

This quote from the Lotus Sutra becomes crucial to Nichiren's mission. He sees himself living in this 'last five-hundred-year period' when the Lotus Sutra must be propagated. It's not just permission but a divine mandate to spread this teaching, even in the face of opposition and persecution.
