The following are words of Grand Masters T’ien-t’ai and Miao-lê urging ordinary people in the Latter Age of Degeneration to have faith in the Lotus Sūtra. Grand Master T’ien-t’ai states in his Words and Phrases of the Lotus Sūtra, “A tree named kōken-ju has a thirty-three foot long bud in the ground. A bird named kalaviṅka twitters more beautifully than any other bird even when it stays in an eggshell.” This explains the merit of the fiftieth person who rejoices at hearing the Lotus Sūtra transmitted one after another by those who rejoice at hearing the Lotus Sūtra. The Buddha graciously revealed the merit of the fiftieth person in order to preach that the merits of an ignorant person who rejoices at having an opportunity to hear the Lotus Sūtra for even a moment are hundred thousand billion times more valuable than the merit of a great saint who has upheld the expedient practices and teachings expounded in the pre-Lotus sūtras for aeons. This is why Grand Master T’ien-t’ai presented these sayings—to show the heart of this sūtra. The koken-ju tree grows thirty-three feet in height a day. The bird kalaviṅka, even when very young, twitters more beautifully than other birds, large or small. Thus T’ien-t’ai compared the long period necessary to practice the expedient teachings to the slow growth of various plants and trees, and the immediate attainment of Buddhahood through the practice of the Lotus Sūtra to the rapid growth of the koken-ju which grows thirty-three feet a day. He also compared great or minor saints who keep expedient teachings to various birds, and ordinary people who intently keep faith in the Lotus Sūtra to the cry of a kalaviṅka bird in the eggshell which is superior to that of other birds.
