[W]hen the Eternal Buddha was revealed in the essential section of the Lotus Sūtra, this world of endurance (Sahā World) became the Eternal Pure Land, indestructible even by the three calamities of conflagration, flooding, and strong winds, which are said to destroy the world. It transcends the four periods of cosmic change: the kalpa of construction, continuance, destruction, and emptiness. Śākyamuni Buddha, the Lord-preacher of this Pure Land, has never died in the past, nor will He be born in the future. He exists forever throughout the past, present, and future. All those who receive His guidance are one with this Eternal Buddha. It is because each of our minds is equipped with the “3,000 modes of existence” and the “three factors,” namely, all living beings, the land in which they live, and the five elements of living beings (matter, perception, conception, volition and consciousness).

This truth was not made clear in the first fourteen chapters of the theoretical section of the Lotus Sūtra. Perhaps it was because the time was not ripe at this stage of preaching the Lotus Sūtra; and capacity of comprehension on the part of the listeners was not yet sufficient.
