Three Books In One Sūtra

[T]he Buddha of Many Treasures attested to the truth of the Lotus Sūtra (in the “Beholding the Stupa of Treasures” chapter), and the numerous Buddhas in manifestation coming from all the worlds in the universe verified the truthfulness of the sūtra by extending their long tongues to reach the Brahma Heaven (in the “Divine Powers of Buddhas” chapter). Thus the “three” Buddhas of Śākyamuni, the Buddha of Many Treasures, and the numerous Buddhas in manifestation verify the truth of the Lotus Sūtra. Therefore, we can say that while the Lotus Sūtra is one book, it is worth three books, its one phrase is worthy of three phrases, and one word is worthy of three words. That is to say, one written Chinese character in the Lotus Sūtra is equipped with the merits of these “three” Buddhas; it is like a wish-fulfilling gem. Regarding the wish-fulfilling gem, one equals a hundred. One gem produces immeasurable treasures while a hundred gems are also equipped with inexhaustible treasures. Suppose we grind a hundred kinds of herbs to make one or a hundred pills. Either one or one hundred, the pill has the same effect as the cure for an illness. This is like one drop of the ocean water being composed of the water of many rivers and one ocean includes the flavors of many rivers. Likewise, the Sūtra of the Lotus Flower of the Wonderful Dharma is a general term for the one book consisting of twenty-eight chapters and each of the twenty-eight chapters has a particular name. Gasshi (Yüeh-shih) is the general term for India, which is also called Gotenjiku (five regions of India). Japan is the general name for our country, and each of the sixty-six provinces of Japan has its own specific name.
