Faith in Nichiren Buddhism is not blind belief or superstition. It means being able to accept the teaching based on reason and to experience and demonstrate its truth amid the realities of daily living. When we thoroughly study the Daishonin’s writings, deepen our faith and confidence through the experiences we gain through this Buddhist practice, and teach others about its validity, we can succeed in propagating the correct teaching in any environment.
