Although I am unworthy, I am a practicer of the Lotus Sūtra. When subjects of the ruler and people of Japan all slight me, the terrestrial deities, who pledged to protect the practicer at the lecture meeting of the Lotus Sūtra, tremble with rage and the heavenly gods shine a light that threatens this country. No matter how many times they admonish this country, their admonition is not heeded at all. Therefore, in the end the terrestrial deities and heavenly gods enter the people, causing the domestic disturbance and foreign invasion.
