[I]f the Lotus Sūtra is the true teaching and the protective deities of the Lotus Sūtra such as the sun and moon do not abandon me, I strongly believe that one day I will be able to return to my homeland and visit my parents’ grave. I wonder what has happened to the King of the Brahma Heaven, Indra, the sun and moon, and the Four Heavenly Kings. Do Goddess Amaterasu and Great Bodhisattva Hachiman not exist in Japan? Did they break their vows to the Buddha to protect the practicers of the Lotus Sūtra and have thus abandoned the practicers? I am not troubled by what may happen to me as a result of not being protected by the heavenly beings. But if you, heavenly beings, who made vows to protect the practicers of the Lotus Sūtra before Śākyamuni Buddha and the Buddha of Many Treasures as well as the many Buddhas from all the worlds in the universe, break your vows and do not protect me now, you will be making a great lie out of the Lotus Sūtra, in which the Buddha has stated in the “Parable” chapter, “I wholeheartedly discard the provisional teachings.” The fault of deceiving Buddhas of entire worlds throughout the universe in the past, present, and future is more fatal and profound than Devadatta’s false words and Honorable Kokālika’s lies. Although the Great King of the Brahma Heaven lives on the top of the region of form and Indra lives on the top of Mt. Sumeru, if they abandon me, Nichiren, their transgressions will become firewood that fuels the flames in the Avici Hell, where they will suffer continuously and never be released from this hell.
