Lotus Sutra in Japanese Culture, {author-numb}Chapter 11, “Apparition of the Jeweled Stupa,” relates that the Stupa in which the Tathāgata Prabhūtaratna (Abundant Treasures) sat rose into the sky and Śākyamuni moved from the earth to the precious Stupa in the sky, seating himself next to Prabhūtaratna. Almost simultaneously, buddhas who had emanated from Śākyamuni gathered from all directions, returning to Śākyamuni, and as they did so, all their worlds were united, becoming the world of the one Buddha. This has been interpreted to mean that the Tathāgata Prabhūtaratna was the past manifestation of Śākyamuni and that Sakyamuni’s taking his seat beside him symbolizes that Śākyamuni has been a buddha eternally. In other words, Śākyamuni is the eternal Buddha, and the return of the buddhas and the unification of their worlds in the world of the one Buddha are expressions of Śākyamuni as the “unifying Buddha.” Thus the “Apparition of the Jeweled Stupa” chapter has been interpreted as a preliminary statement of the theme of chapter 16, the eternal life of the Tathāgata. Both chapters, however, advocate bodhisattva practices and activities in this sahā world of the decay of the law, and expound entrusting the law to bodhisattvas. This being the case, the concepts of the precious Stupa rising up, the gathering of buddhas who are emanations of the eternal Buddha, and the united world of the one Buddha should be understood as expressions from the standpoint of advocacy of bodhisattva practices.
