Nichiren's Senji-Shō, p19The Pure Land for Nichiren was not a world situated at some far place, but a spiritual realm which would be realized on this earth whenever the Lotus Sutra was preached to the people of the Age of the Last Law. Whenever humanity returned to the faith and followed the Buddha’s teaching as found in the Lotus Sūtra, then, Nichiren believed, would come the end of the Age of the Last Law.
Nichiren began his public teaching by calling for the restoration of Tendai Buddhism as the basis for national salvation in the Age of the Last Law. Three times he approached the government and twice he was rebuked and exiled. He saw his mission as staying in the world during the Age of the Last Law in order to transform the world into the true Buddha Land.
