Food for thought.
The irony is that the moment you view Earth as a school, it immediately becomes a prison because you submit to keep evolving forever not knowing where graduation is. Yet the the moment you view Earth as a prison, it immediately becomes a school because you now have the goal and process of 'breaking free'.
If an IS-BE cannot die and is eternal, it is perfect in the sense that it doesn't need to learn/grow, perhaps only to experience, since perfection cannot be more perfect. However if an IS-BE can be deceived into being trapped on a prison planet in a prison body, doesn't that indicate imperfections of the IS-BE and that it can indeed learn/grow to not being deceived by infinite varieties of tricks (thereby is continuous schooling)?
