Grand Master Dengyō has said in his Outstanding Principles of the Lotus Sūtra: “You should know this. As basic canons of other schools are not the supreme sūtras, those who uphold those sūtras are not enlightened above all the people. The basic canon of the Tendai Lotus School is the supreme sūtra, so those who uphold it are enlightened above all the people. These are the words of the Buddha. How can this be self-conceit?” When a mite riding on the tail of a dragon-horse, which can run 1,000 ri a day boasts that it (mite) can run 1,000 ri a day, or when a follower of the Wheel-turning Noble King claims to run around the world in a second, who would blame or suspect him? We should remember by heart: “How can this be self-conceit?” If so, since those who uphold the Lotus Sūtra exactly as it is are above the King of the Brahma Heaven and Indra, they should be able to have Mt. Sumeru carried by asura demons and a great ocean swallowed up by dragons.
