The narrative of Great-Universally-Excelling-Wisdom Buddha can be considered an introduction to the “Realm of Origin” (Hommon), which is the key philosophy of the Lotus Sutra. In some ways, this story foreshadows the fundamental view of the Realm of Origin (Hommon), which will be revealed in later chapters, especially in Chapter Sixteen, “The Duration of the Life of the Buddha.” First, the facts that Great-Universally-Excelling-Wisdom Buddha expounded the Lotus Sutra a long time ago, and the sixteen princes kept it and continue to expound it even now, indicate that the Lotus Sutra is the eternal truth, transcending the concepts of time and space. Second, the fact that the Buddhas of the worlds of the ten directions obtained enlightenment through the Lotus Sutra suggests that all the teachings of and faith in the Buddhas are to be merged into the teachings of and faith in the Lotus Sutra. Finally, the central cosmic figure among these Buddhas is Sakyamuni, who resides in this World of Endurance (Saha-world).
