Yoshiro Tamura, "Introduction to the Lotus Sutra", p102[In chapter 11] there is the sudden appearance of the Treasure Stupa, the two buddhas sitting side by side, the gathering together of the buddhas who are embodiments or representatives of Shakyamuni, the united buddha-land, the purification of the Sahā world, and so on. These things were traditionally understood to imply that Shakyamuni Buddha is the Everlasting Original Buddha, and were taken to herald chapter 16, “The Life of the Tathagata.” But chapter 11 also teaches the propagation of bodhisattva practice, which is its ultimate purpose. We can see this in the following:
Who is able to teach the Wonderful Dharma Flower Sutra everywhere throughout this world? Now indeed is the time. Before long the Tathagata will enter nirvana. So that it will last forever, the Buddha wants to entrust this Wonderful Dharma Flower Sutra to someone.
Thus, it encourages actual bodhisattva practice in this world during the latter days and teaches the entrusting of the Dharma to such bodhisattvas.
