I have never seen or heard of any man of knowledge who recited “Namu Myōhō Renge Kyō” himself and advised others to do so during the 700-year period between the reigns of Emperor Kimmei, when Buddhism was introduced to Japan, and the latest emperor. It is only natural that when the sun rises, stars disappear; and when a wise king rises to power, an ignorant king is destroyed. So when the True Dharma spreads, provisional ones decline; and when a man of knowledge recites “Namu Myōhō Renge Kyō,” ignorant people follow him, just as a body is followed by its shadow and a sound is followed by its echo. Consider what is said above. I, Nichiren, undoubtedly am the prime practicer of the Lotus Sūtra in Japan. No one in China, India, and in the whole world is comparable to me.
