Nichiren on wiping out grave offenses

"Now if I, Nichiren, insignificant person that I am, were to go here and there throughout the country of Japan denouncing these slanders, then innumerable persons among the four categories of Buddhists who follow erroneous doctrines would in one instant join their innumerable voices in reviling me. At that time the ruler of the nation, allying himself with those priests who slander the Law, would come to hate me and try to have me beheaded or order me into exile. And if this sort of thing were to occur again and again, then the grave offenses that I have accumulated over countless kalpas would be wiped out within the space of a single lifetime. Such, then, was the great plan that I conceived, and it is now proceeding without the slightest deviation. So, when I find myself thus sentenced to exile, I can only feel that my wishes are being fulfilled.

Nevertheless, being no more than an ordinary person, I have at times been apt to regret having taken such a course. And if even I am troubled by such feelings, then how much more so in the case of a woman such as your wife, who is unaware of all the circumstances surrounding the matter. Persons like you and her do not have full knowledge of the Buddhist teachings, and it pains me to think how greatly you must regret that you ever chose to follow Nichiren. And yet, contrary to what might be expected, I hear that you two are even firmer and more dedicated in your faith than I myself, which is indeed no ordinary matter. I wonder if Shakyamuni Buddha himself may have entered your hearts, and it moves me so that I can barely restrain my tears.' -- On Rebuking Slander of the Law and Eradicating Sins"
