For Nichiren, the Lotus Sūtra alone fully revealed the inherence of the buddha realm in all nine realms of unenlightened beings: By chanting its title, Namu Myōhō-renge-kyō, which instantiates the wisdom of all buddhas, even the most deluded person, he said, can manifest the buddha realm directly. Nichiren likened this to fire being produced by a stone taken from beneath the depths of water or a lamp illuminating a place that has been dark for millions of years.
