“While their ambiguous status unsuits them as primary sources for Nichiren’s ideas…” — Dr. Jacqueline Stone
I am not saying that Jacqueline Stone is the final arbiter of an understanding of Nichiren’s ideas and his philosophy of salvation but L brought up a point, referencing her famous and interesting dissertation, Some Disputed Writings in the Nichiren Corpus. I would say, however, that this snippet is the crux of our argument against the Soka Gakkai’s interpretation and manifestation of Nichiren Lotus Sutra Buddhism. The SGI utilizes the ambiguous works as the primary source for Nichiren’s ideas while discarding many of Nichiren’s ideas found in the known authentic works [primary sources]. The true Nichiren faith and practice is not found in the Soka Gakkai.  As an aside, the Nichiren Shoshu depends on less than the ambiguous works. It depends on known and near universally accepted forgeries.
