Step-by-step explanation:
The student asked about the practices of Soka Gakkai under Nichiren Buddhism. Soka Gakkai is a movement within Mahayana Buddhism, specifically Nichiren Buddhism, which originated in Japan. This form of Buddhism primarily practices the chanting of the Lotus Sutra's title, 'Nam-myoho-renge-kyo,' as its main form of meditation and devotional activity. Unlike Chan Buddhism or Zen Buddhism, which emphasize meditative practices, Nichiren Buddhism, and thereby Soka Gakkai, focus more on chanting as well as studying the teachings of Nichiren, a 13th-century Japanese Buddhist priest. Followers believe that by chanting and engaging in individual and communal activities, they can attain personal enlightenment and contribute to peace, culture, and education in society. The practice promotes values like nonviolence, honesty, selflessness, tolerance, and moral living, and the belief in the power of the Lotus Sutra to bring about positive change in one's life and the world.
