In this paper, I investigate the theory of 3,000 realms contained in one mind and the 10 Worlds, grounded in the concept “Hosshaku Kempon” 発迹顕本,from Nichiren’s 日蓮 (1222–1282) Lotus Sūtra-oriented thought, specifically the Bodhisattva vow of giving relief to all sentient beings in the Mappō 末法 period.
I focused on the Kaimokushō 開目抄,a text representative of the Sado period of Nichren’s exile, and extracted and studied the dogma from the viewpoint of these teachings.
Five items are taught as the dogma of the Bodhisattva vow to give relief to all sentient beings in the Mappō period: the theory of truth of the 3,000 realms contained within one mind; people belonging to the two vehicles can become a Buddha; Devadatta and the Dragon Girl will attain Buddhahood; three types of adversaries; he theory of seeds of Buddhahood in the 3,000 realms contained within one mind.
