The five characters of Myō, Hō, Ren, Ge, and Kyō are the precious doctrine preached by Śākyamuni Buddha when He entered the Stupa of Treasures sitting by the Buddha of Many Treasures. Buddhas in Manifestation gathered together from all over the universe. The Buddha then invoked bodhisattvas from underground, chose the essence of the Lotus Sūtra and expounded on it for us people in the Latter Age of Degeneration. There should be no doubt about its merit in this world.
