I have never heard Bashar mention it.
What he does mention is that "Reality is Meaningless" in the sense that no event or circumstance has any implicit meaning. It's up to us to assign meaning, good, neutral or bad.
The "Prison Planet" idea is interesting as a story.
With Intergalactic Wars and Planetary destruction in our Solar System, it gets to be a really complex puzzle to solve.
Personally, I think there is a lot of "Retributions" that run well past the Human lifespan.
There are definitely some people on Earth that are pretty "Free" to do what they want, and then others a lot less so.
Are particular Racial or Religious groups perpetually punished as a retribution for various wars? through the course of History? I don't know but when you look closely it seems like some are. It's almost in their DNA, it could be argued.
