The Writings of Nichiren Daishonin are a compilation of letters and treatises written by Nichiren himself to his followers.
He was persecuted throughout his life by the Japanese government and by religious leaders who considered his revolutionary teachings a threat to their continued authority. Nevertheless, the letters he wrote to his followers, often under the most dire conditions, illustrate that even in the midst of the greatest challenge, he was able to realize the great beauty of life and feel joy and compassion for others.
These letters and treatises, more than 400 of which remain today, are collected in English as The Writings of Nichiren Daishonin, vols. I and II, and are the primary study material for SGI members. Search The Writings of Nichiren Daishonin online: http://www.sgilibrary.org
