SGI's teachings and Nichiren's teachings

"Let’s eternally protect and perpetuate the truth and justice of the way of mentor and disciple. The strength of the bond between mentor and disciple is determined by the disciple’s efforts. Uphold the mentor’s teachings and manifest them in your daily activities, thus realizing the principle of “practice equals victory. You are individuals with a mission. Protect the mentor and prevail over injustice. Be genuine lions and dedicate your lives to upholding justice and truth. Live your life straight and true according to the guiding principles taught by the mentor. When we brim with a strong resolve based on the spirit of “together with the mentor” and “for the mentor’s sake” we are able to manifest unfathomable strength. Let’s become disciples with sun-like qualities." -- SGI teachings

“Yet it was not I, Nichiren, who made these three important pronouncements. Rather it was in all cases the spirit of the Thus Come One Shakyamuni that had entered into my body. And having personally experienced this, I am beside myself with joy.” -- Nichiren's teachings
