Eventuelly, every soul that participates in the Earth Game will merge back into their respective Higher Selves.
That is when each of them has cleared up all the “Karma”, i.e. “open bills” that they have between each other.
This can take a very long time but eventually no one is left behind, be it on physical earth or on the various astral levels of earth.
The question is always how much pain and suffering some souls want to endure until they learn their lessons (their conceptual realizations)?
To reach so called “Escape Velocity” for mastering and leaving the Earth Game as a “complete Higher Self”, all the emotional bagage that pulls one back into the physical and lower astral, needs to be healed and let go.
It is important to remember that the MAIN Earth Game is NOT played here in the physical but on Earth’s various astral planes!
The physical plane is the “hardcore difficulty” server of the game.
It is not even necessary to physically incarnate in this game and all can be learned and realized by playing the game on the astral levels only.
However, incarnating into the physical is like self development on ultra steroids and for souls who are impatient (like us) and who like to speedrun things (like us).
Souls like us literally cannot await it to finally become “like the Sun”!
Many of us are here because we so are excited “to become more” that we are up to the hardest challenges in order to grow.
With regards to “Karma” and “open bills” of murderers and similar folks, here is my understanding of this:
