This world is the eternal pure land

"The saha world Shakyamuni revealed in the Juryo chapter is the eternal pure land, impervious to the three calamities and the four cycles of change. In this world the Buddha is eternal, transcending birth and death, and his disciples are also eternal. That is why the three thousand worlds or the three realms of existence are within our own lives. The Buddha did not reveal this truth in the first fourteen chapters of the Lotus Sutra because the time was not right and he found his disciples not yet able to grasp the truth." -- The True Object of Worship
