Nichiren on those who turn their backs on Shakyamuni Buddha

"Next, they have abandoned their father, Shakyamuni Buddha, and hence stand accused of the five cardinal sins. How can they escape falling into the hell of incessant suffering? And finally, they have turned their backs on their teacher, Shakyamuni Buddha, and thus are to be numbered among those who commit the seven cardinal sins. How could they fail to sink into the evil paths of existence?" -- Nichiren
