Nichiren teaches...

"This I will state. Let the gods forsake me. Let all persecutions assail me. Still I will give my life for the sake of the Law. Shāriputra practiced the way of the bodhisattva for sixty kalpas, but he abandoned the way because he could not endure the ordeal of the Brahman who begged for his eye. Of those who received the seeds of Buddhahood in the remote past and those who did so from the sons of the Buddha Great Universal Wisdom Excellence, many abandoned the seeds and suffered in hell for the long periods of numberless major world system dust particle kalpas and major world system dust particle kalpas, respectively, because they followed evil companions.Whether tempted by good or threatened by evil, if one casts aside the Lotus Sutra, one destines oneself for hell. Here I will make a great vow. Though I might be offered the rulership of Japan if I would only abandon the Lotus Sutra, accept the teachings of the Meditation Sutra, and look forward to rebirth in the Pure Land, though I might be told that my father and mother will have their heads cut off if I do not recite the Nembutsu—whatever obstacles I might encounter, so long as persons of wisdom do not prove my teachings to be false, I will never yield! All other troubles are no more to me than dust before the wind." - Opening of the Eyes
