Rissho Ankoku-ron
(Monthly Gosho Passage September 2009)
You must immediately renounce your erroneous belief and take faith in the supreme teaching of the one vehicle of the Lotus Sutra. Then, this entire threefold world will become the Buddha land. How could the Buddha land ever decline? All the lands in the ten directions will transform into treasure realms. How could a treasure realm ever fall to ruin? If the nation never declines and the land is indestructible, you will find safety and peace of mind.
(The Gosho of Nichiren Daishonin Vol.2, p.42)
