I now realize, though dimly, the heart of the eleventh chapter of the Lotus Sūtra, “Appearance of the Stupa of Treasures.” It is stated in this chapter: “Even a man as powerless as I can throw Mt. Sumeru over to countless numbers of Buddha lands. … Even more so, it is not easy to uphold the Lotus Sūtra in the evil world after the death of the Buddha.” Grand Master Dengyō interprets this in his Outstanding Principles of the Lotus Sūtra (Hokke shūku): “The Buddha has determined that it is easy to spread the sūtras which are shallow in meaning, and difficult to spread those which are profound in meaning. A man should leave the shallow and take the deep. Therefore, Grand Master T’ien-t’ai, putting faith in Śākyamuni Buddha, spread the Lotus Sūtra in China; and all the kinsfolk of Mt. Hiei, receiving the teaching of the Lotus Sūtra from T’ien-t’ai, spread it in Japan.”
