The means by which all people could awaken to the fact that the truth of life and the universe exists within their own lives, and actively manifest that truth, was established by the Daishonin. Moreover, this truth is the enlightened wisdom of all Buddhas and is fully revealed in the Lotus Sutra, which is the highest teaching of Buddhism. By basing ourselves on that truth, we can lead lives of supreme value. The Daishonin’s Buddhism opened this realm of faith so that it was accessible to anyone, anywhere, anytime, no matter what their background. It would be no exaggeration to say that the practice of chanting daimoku in Nichiren Buddhism is what gave rise to a ‘Buddhism of the people’. This practice of chanting daimoku is indeed the supreme Buddhist practice, making it possible for us to fundamentally transform our lives.
