[R]egarding the daily practices, the daimoku of the Lotus Sūtra should be chanted, “Namu Myōhō Renge Kyō.” If possible, a verse or phrase of the Lotus Sūtra should respectfully be read. As an auxiliary practice one may say a prayer to Śākyamuni Buddha, the Buddha of Many Treasures, the numerous Buddhas throughout the universe, various bodhisattvas, Two Vehicles, Heavenly Kings, dragon gods, the eight kinds of gods and demi-gods who protect Buddhism as one wishes. Since we have many ignorant people today, the “3,000 existences contained in one thought” doctrine may be difficult to contemplate from the beginning. Nevertheless, those who wish to study it are encouraged to do so from the start.
