The Lotus Sūtra Wisdom of Insight Manual by Tripiṭaka Master Amoghavajra is based on the “Appearance of the Stupa of Treasures” chapter [of the Lotus Sūtra], and it regards Śākyamuni Buddha and the Buddha of Many Treasures of the Lotus Sūtra as the honzon, but this idea is not the true intention of the Lotus Sūtra. The daimoku (sacred title) of the Lotus Sūtra is the honzon of Śākyamuni Buddha, the Buddha of Many Treasures and the Buddhas of the worlds throughout the universe. This daimoku should be the honzon for the practicer of the Lotus Sūtra.
