If you don't want to come back to earthly life again, then you are ready for the next level/stage...

There are people that want to come back to Earth... or to be more precise earthly-life.

Some people want to explore life on earth... O god no!

So if you have had enough - completely enough of it - then you can go to the next level.

But there are exceptions - when there is special work that you need to do on Earth or help that you need to provide - but you can't do the work unless you have realised your Self / Soul.
