QUESTION: Are there any dharmas T’ien-t’ai and Dengyō did not propagate yet?
ANWER: Yes, there are.
QUESTION: What are those True Dharmas?
ANSWER: There are three. They are what the Buddha bequeathed to those in the Latter Age of Degeneration, namely the True Dharmas, which masters such as Kāśyapa, Ānanda, Aśvaghoṣa, Nāgārjuna, T’ien-t’ai, and Dengyō did not yet spread.
QUESTION: What do they consist of?
ANSWER: The first is the Most Venerable One (honzon). All the people in Japan as well as the rest of the whole world should revere the Lord Buddha Śākyamuni of the essential section as the Most Venerable One. That is to say, the Most Venerable One should be the Buddha Śākyamuni and the Buddha of Many Treasures in the Stupa of Treasures. The other Buddhas standing outside the Stupa and four bodhisattvas such as Superior Practice Bodhisattva should be their attendants.
The second is the precept dais based on the doctrine of the essential section of the Lotus Sūtra.
The third is the daimoku (title) of the Lotus Sūtra. All the people in Japan, China, and everyone in the whole world, regardless of being wise or foolish, should chant “Namu Myōhōrengekyō” single-mindedly forgetting everything else.
