The exclusive faith and practice of the Lotus Sutra in Mappo is a narrow path with one door (Lotus Sutra Chapter 3). If one could become enlightened and create kosen-rufu through, Christianity, Hinduism, Sikhism, Islam, the Soka Gakkai, the Pali Cannon, or the Three Vehicles, the Lotus Sutra and Nichiren would have taught the path wide with many doors. Those who assert otherwise are devils to be repudiated.
The reason the world is in the state it's in, a state of sadness, greed, anger, stupidity, impurity, and prejudice (rather than joy, equanimity, magnanimity, compassion, purity, and empathy), is precisely because of the establishment of mistaken beliefs and inferior teachings that leave the people prostrate on the ground. Unless and until the Lotus Sutra alone flourishes, we will never have a world based on the enlightened life of the Buddha and the Law of Namu myoho renge kyo.
This belief is fundamental to the teachings of the Lotus Sutra and Nichiren Daishonin and the forceful practices are the way to Establish the Right Law. Declaring that the Lotus Sutra alone leads to Supreme Enlightenment and all other teachings lead to hell, one is a disciple and believer of Nichiren Daishonin. It is self apparent to the disciples and believers of the Lotus Sutra and Nichiren Daishonin, those with clear minds and those keenly able to correctly observe the world, that it is Christianity, Islam, Hinduism, Judaism, secular humanism, belief in the sanctity of science, and heretical provisional Buddhism which has brought us to the brink. The elimination of these diseased religions and philosophies will bring about the land of eternal quiescent light.
