Letter to the Wife of Shijō Kingo

Is there anything which is brighter than the sun and the moon? Is there anything which is more pure than the lotus blossom? The Lotus Sutra is the sun and the moon and the lotus flower. Therefore, it is called the Sutra of the Lotus Flower of the Wonderful Law
I, Nichiren, am also like the sun and moon and the lotus flower.

(Explanatory note)

There is nothing which is brighter than the sun and moon. There is nothing which is purer than the lotus blossom. The content of the Lotus Sutra is indeed the brightness of the sun and moon and the pureness of a lotus blossom. Therefore, it is called the Sutra of the Lotus Flower of the Wonderful Law. The sun and moon and the lotus blossom are Nichiren’s life and soul. (This is indeed the origin of Nichiren’s name.)
