Nichiren (日蓮; February 16, 1222 – November 21, 1282) was a Buddhist monk who lived during the
Kamakura period (1185–1333) in
Japan. Nichiren taught devotion to the
Lotus Sutra, which claims to contain
Gautama Buddha's teachings towards the end of his life, as the exclusive means to attain enlightenment. Nichiren believed that this sutra contained the essence of all of Gautama Buddha's teachings related to the laws of
causality,
karma, and leading all people without distinction to enlightenment. This devotion to the sutra entails the chanting of
Namu Myōhō Renge Kyō "homage to the
Lotus Sutra", a phrase referred to as the
daimoku, as the essential practice of the teaching.
