"Namu Myoho renge kyo Thus Come One", "Namu Myoho renge kyo Buddha", or even "Myoho renge kyo Buddha" was never once taught in the Lotus Sutra nor in the writings of Nichiren Daishonin. "Bodhisattva-Buddha" and "SGI-Buddha" too were never taught or even intimated in the Lotus Sutra nor writings of Nichiren. Soka Gakkai has made up their own "Buddhism".
Nichiren teaches us to have the same faith and practice as he. Soka Gakkai is the faith and practice of Daisaku Ikeda. Soka Gakkai "Buddhism" is really Ikedaism or SGI psudo-Buddhism.
