The state of mind with which we meet our death will greatly influence the course of our lives over eternity. Granted, if one is unconcerned by how one dies, or if one dismisses any connection between this existence and the next, then there probably isn’t any need to practice Nichiren Buddhism. But the truth is that life is eternal, that our existence continues even after we die. Moreover, during the latent stage of death before rebirth, we cannot change the essence of our lives, we cannot carry out Buddhist practice. Only while we are alive as human beings can we practice Buddhism.
