Nissen ［日仙］ (1262–1357): A disciple of Nichiren; after Nichiren’s death one of Nikkō’s six elder disciples. A native of Kai Province in Japan, he studied under Jakunichi-bō Nikke, also later one of the six elder disciples. In 1334, the year after Nikkō’s death, Nissen had a debate with Nichidai, another disciple of Nikkō, on the topic of whether or not it is necessary to recite the “Expedient Means” (second) chapter of the Lotus Sutra as a daily practice. Nissen insisted that it is not, basing his argument on the position that one cannot attain Buddhahood through the theoretical teaching, or the first half of the sutra, which includes the “Expedient Means” chapter. They did not reach a definite conclusion. Nissen later went to Sanuki Province, where he devoted himself to propagation. See also Nichidai.
