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.
