Nichiren would defrock the Nichiren Shu priest Ryusho

"I generally do not approve or support a practice style or teaching that is exclusive, one way only, the correct right way or any other such notions of exclusivity. I think there are many vehicles which all are leading to the sngle vehicle of realization we are all Buddhas and we are all unique" -- Ryusho

“I had gone to many centers of the religion during those twenty years, in the quest of Buddhist truths. The final conclusion I arrived at was that the truth of Buddhism must be one in essence. Many people lose themselves in the labyrinth of learning and studies, through thinking that every one of the diverse branches might help to the attainment of Buddhist ideals.” -- Nichiren (Works pp 1770-71)
