As I contemplate the Buddhist scriptures, it is stated in the Sūtra of the Golden Splendor (translated by Dharma-Kema), “The Sun Deity and Moon Deity regain their vigor upon hearing this sūtra.” The Sūtra of the Golden Splendor (translated by I-ching) states, “It is due to the power of this sūtra that the sun and moon revolve around the four continents.” That is to say, it is the power of the Buddhist Dharma that causes the sun and moon to circle the four continents. Those two versions of the Sūtra of the Golden Splendor are expedients to the Lotus Sūtra. Compared to the Lotus Sūtra they are like milk against “clarified butter” or gold against a “treasure-gem.” If even the taste of such inferior sūtras can make the sun and moon revolve around the four continents, how much more so can the daigo taste of the Lotus Sūtra accomplish? Therefore, the Sun Deity attended the preaching of the “Introduction” chapter of the Lotus Sūtra as Fukō Tenji (Universal Fragrance), and was granted future Buddhahood as the Kaji Nyorai in the “Teacher of the Dharma” chapter.
