As difficult as it is to believe, this 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
