Nam Myōhō Renge Kyō

Namu Myōhō Renge Kyō (南無妙法蓮華経) (also known as Nam Myōhō Renge Kyō) (English: Devotion to the Mystic Law of the Lotus Sutra or Glory to the Sutra of the Lotus of the Supreme Law) is the central mantra chanted within all forms of Nichiren Buddhism as well as Tendai Buddhism. The famous Tendai Monks Saicho and Genshin are said to have originated the Daimoku although Nichiren is known as the greatest proponent. The mantra is an homage to the Lotus Sutra which is widely credited as the "king of scriptures" and "final word on Buddhism". According to Jacqueline Stone, the Tendai founder Saicho popularized the mantra "Namu Ichijo Myoho Renge Kyo" as a way to honor the Lotus Sutra as the One Vehicle teaching of the Buddha. According to Richard Payne, the Tendai monk Genshin popularized the mantra "Namu Amida, Namu Kanzeon, Namu Myoho Renge Kyo" to honor the 3 jewels of Japanese Buddhism. Nichiren, who himself was a Tendai monk, edited these chants down to "Namu Myoho Renge Kyo" and Nichiren Buddhists are responsible for its wide popularity and usage all over the world today.

The words Myōhō Renge Kyō refers to the Japanese title of the Lotus Sūtra. The mantra is referred to as daimoku (題目^?) or, in honorific form, o-daimoku (お題目) meaning title and was first revealed by the Japanese Buddhist priest Nichiren on the 28th day of the fourth lunar month of 1253 at Seichō-ji (also called Kiyosumi-dera) in present-day city of Kamogawa, Chiba prefecture, Japan.
