I wasn't really that clear above, so to amend that post, I have heard at least two writers refer to this place as in part a prison planet. Some of the folks that are here were drummed out of better places for misbehavior, intentional or otherwise. Bob Monroe talks about this toward the end of his 'Wednesday evening talk'. I know I have heard words to this effect from another writer on this general topic (of beings of the earth) as well, but can fetch up at the moment who it was. Not all people here are here under those conditions though, apparently. As the tales run, some came to help, some came to hide out, others came to learn... some might well have got here by accident or lottery or chance of some kind.
Interesting. I've never heard the "prison" concept before. It's certainly humbling to think that I'm here because I misbehaved in a "better" reality frame once upon a time.
Tom refers to Earth as a learning lab fairly often in MBT, as did Monroe. In the Asheville workshop Tom states that this PMR is more at the preschool or daycare level as far as education goes... seems like we all have a lot of work to do.
