Nichikan's and Ikeda's role is to subborn True Buddhism.

The Original Buddha Shakyamuni's role is to be the object of worship in terms of the Person. Our role is to worship Him. Nichiren's role is to reveal the object of worship which he taught, "is in no way my invention" [because it is impossible to create or invent that which is uncreate and eternal]. Our role is to spread the five or seven characters of the Daimoku and the object of worship that Nichiren revealed. Nichikan's and Ikeda's role is to subborn True Buddhism.
