At first only I, Nichiren, started chanting the daimoku, Namu Myōhō Renge Kyō, but then two, three, then one hundred people, gradually began chanting it. This will continue in the future. Isn’t this what emerging from the earth means? When an innumerable number of people emerge from the earth and this Wonderful Dharma spreads extensively, there will be no mistake, just as a shooting arrow never misses the earth, Japan will be filled with people chanting Namu Myōhō Renge Kyō. You should therefore establish your fame as the practicer of the Lotus Sūtra and devote your life to it.
