Another important implication that [the Life Span] chapter held for Nichiren was indeed this very possibility of realizing the buddha land in the present world. In the “Parable” chapter of the Lotus Sūtra, Śākyamuni describes the world as a “burning house” in which there is no safe place. But now in the “Lifespan” chapter, having revealed his true identity as the primordially awakened buddha, Śākyamuni declares that, even in the fire that destroys the world at the end of the cosmic cycle, his land — the present world — is “tranquil” and “never decays”; it is a place where sentient beings are “joyful.” This is the realm depicted on Nichiren’s mandala. Alluding to this sūtra passage, Nichiren writes, “Now the Sahā world of original time is the constantly abiding pure land, liberated from the three disasters and beyond the [cycle of the] four kalpas [eons]. Its buddha has not already entered nirvana in the past, nor is he yet to be born in the future. And his disciples are of the same essence. This [reality] … is the three thousand realms of one’s own mind.”
