Nichiren
"Chanting "Namu-Myohorengekyo" swallows up the functions of "Namu-Amida-Butsu," "Namu-Dainichi-shingon," and "Namu-Kanzeon-bosatsu" as well as all the Buddhas, sutras, and bodhisattvas. All these will be of no use without the functions of the Lotus Sutra. This can be seen by everyone, for it has been realized in front of everyone. When I, Nichiren recite "Namu-Myohorengekyo" the function of "Namu-Amida-Butsu" disappears just as the moon wanes, the tide ebbs, grasses in autumn and winter wither and ice melts under the sun."
