According to Chih-i, within the special transmission to the bodhisattvas who appeared from beneath the ground is contained four great mysteries which according to Nichiren are Namu Myoho Renge Kyo. The four mysteries are all contained with the Lotus Sutra and they are, 1. All the teachings of the Buddha are here, 2. All the supernatural powers of the Buddha are here, 3. The hidden treasury of the core Buddhist teachings are here, 4. All the achievements of the Buddha are here. By our practice of Namu Myoho Renge Kyo, and our determined efforts to know and live the Lotus Sutra we gain access to the four mysteries in this special transmission.
