To Myoho Renge Kyo, or the Lotus Sutra, we add our devotion as expressed in Namu. Namu activates Myoho Renge Kyo in our lives. The degree to which Namu is present in our lives, in our actions, will determine the degree of the manifestation of Myoho Renge Kyo. This manifestation appears both in our internal self as well as our external self, our environment.
