The basic doctrine is that if a person believes in the correct principal image Honmon Kaidan no Dai-Gohonzon (the Great Object of Veneration of the Sanctuary of the True Teaching)) and practices daimoku (Nichiren chant) with Jigyo Keta (benefiting oneself and benefiting others), anyone can become Buddha in his or her lifetime.
教義の基本は、正しい本尊（本門戒壇之大御本尊）を信じて自行化他に題目を修行しさえするならば、どんな者でも必ず一生のうちに成仏できる、ということである。
