Nam Myōhō Renge Kyō (also, in some schools Namu Myōhō Renge Kyō; Devotion to the Law of the Lotus Flower Scripture) is a mantra that is chanted as the central practice of all forms of Nichiren Buddhism. The mantra is referred to as Daimoku (also, in some schools, O-daimoku) and was first revealed by the Japanese Buddhist teacher Nichiren on the 28th day of the fourth lunar month of AD 1253 at Kiyosumi-dera (also, Seichōji) near Kominato in current-day Chiba, Japan. The practice of chanting the daimoku is called shōdai. The purpose of chanting daimoku is to attain perfect and complete awakening (enlightenment).

The pendant is made of high grade surgical steel (316L Stainless).
