My Comment: What does it mean—eternity? Material reality is just an illusion; it does not exist.
Our world will exist until we reach the upper world. As soon as humanity begins to rise in its mass to the spiritual world, our world will evaporate, dissolve as in fog, and cease to exist.
You will understand this when entering the ladder of attaining the upper worlds. Remaining in our world, you will see that this really has to happen—our material world will evaporate in the future because it exists only in our sensations.
Remark: But meanwhile people are making every effort to somehow leave their mark in history, in any form.
My Comment: What is left for them? In this way their egoism seeks to establish their “I.”
