QUESTION: As ordinary people who live in the evil latter days, what should we define as the honzon?

ANSWER: We should regard the daimoku of the Lotus Sūtra as the honzon.

QUESTION: According to which sūtra passages or which learned monk’s interpretation?

ANSWER: The “Teacher of the Dharma” chapter of the Lotus Sūtra, fascicle 4, says: “Medicine King! Erect a Stupa of the seven treasures in any place where this sūtra is expounded, read, recited or copied, or in any place where a copy of this sūtra exists! The Stupa should be tall, spacious and adorned. You need not enshrine My relics (śarīras) in the stupa. Why not? It is because this sūtra contains My perfect body.” In the “Nature of the Buddha” chapter of fascicle four of the Nirvana Sūtra it is said: “Kāśyapa. Each Buddha regards the Dharma as master. For that reason the Buddha reveres and makes offerings to the Dharma. Because the Dharma is eternal, each Buddha is also eternal.” Grand Master T’ien t’ai declares in his Lotus Meditation Repentance: “Make a raised seat in the training hall and place the Lotus Sūtra there. There is no need to place a statue of the Buddha or a relic or other sūtras. Only the Lotus Sūtra is needed.”
