These three great secret dharmas are certainly what I, Nichiren, at the head of the group of bodhisattvas emerged from underground received from Lord Śākyamuni Buddha orally more than 2,000 years ago. Therefore, what I practice today are the “actual” three great secret dharmas revealed in “The Life Span of the Buddha” chapter, which are exactly the same as what was transmitted on Mt. Sacred Eagle without a shred of difference.
