In “On Repaying Debts of Gratitude,” the Daishonin writes, “If Nichiren’s compassion is truly great and encompassing, Nam-myoho-renge-kyo will spread for ten thousand years and more, for all eternity” (WND-1, 736). We must remember that kosen-rufu advances due to the boundless compassion of the Daishonin. It is our supreme honor to shoulder that noble undertaking.
