Nichiren urges us to earnestly chant Nam-myoho-renge-kyo, even just once or twice, stressing that if we do so we will definitely attain enlightenment. Now some might immediately think: “All right! I’ll just put faith aside and take it easy, then embrace faith seriously a year before I die.” But Nichiren’s words in this instance are meant to spur his followers to devote greater efforts to their Buddhist practice, emphasizing the beneficial power of chanting even a single daimoku. The correct way to read the Gosho is to always interpret Nichiren’s words from the standpoint of strengthening our faith.
