Nichiren Daishonin states in “Reply to Priest Takahashi”:
The Hinayana sutras, the Mahayana sutras as well as the Lotus Sutra—all these teachings can no longer work as medicine to treat the people’s illnesses. Only the words of these sutras are still in existence. Their illnesses will be too serious while these medicines are too ineffective. At that time, Bodhisattva Jōgyō will make his advent in order to bestow upon all people in the entire world the five characters of Myo-Ho-Ren-Ge-Kyo.
