"Believe in the Gohonzon with your whole heart. The heart of the Lotus Sutra is the guidance of the High Priest. Never accept even one word of my teachings without having first received guidance from the High Priest. Without practice and the High Priest's guidance there is no Buddhism." --"Guidance Gosho" NSIC translation

"Believe in the Gohonzon with your whole heart. The heart of the Lotus Sutra is the mentor-disciple relationship. Never accept even one word of my teachings without having first received guidance from the lay president of my Sangha. Without practice and the President's guidance there is no Buddhism." -- "Guidance Gosho" Soka Gakkai translation

"Believe in the Gohonzon with your whole heart. The Buddha’s will is the Lotus Sutra, but the soul of Nichiren is nothing other than Namu-myoho-renge-kyo. Miao-lo states in his commentary that the heart of this sutra is the revelation of the Buddha’s original enlightenment and his immeasurable life span." -- Nichiren
