I doubt I'm off on what he said since he did say it in plain English. Anyway, it sounds to me like you are assuming quite a few things yourself. I'd rather just stick to my initial question. Also, he book is pretty easy to read and understand. It's not like reading a book on high level mathematics or string theory. It's pretty basic. Anyway, is this research/data being made available by the Monroe Institute? If it's available for a price it throws up MANY red flags. I've read most of Monroe's books and he struck me as someone who wanted to share this knowledge with the world and Campbell's book made it sound like Monroe also wanted to have this validated by the scientific community as a whole. So much screams scam or greed to me about this. If Campbell is telling the truth then the research exists and all it would take is to hand it over to a few researchers for verification. Why hasn't this been done?
If the book is so basic then why are you asking such basic questions? A person who actually comprehends the material wouldn't bother asking these kinds of questions because they would already know the answer. Perhaps you aren't as smart as you think you are. In particular, the aside in the book where Tom jokes about "The Three Stooges" contains your answer. Yes, your question is likened to the level of Larry, Curly, and Moe.
You missed about 90% of the book's information. Think about that.
If you're almost done reading it I recommend you give it another go. Watching some more of Tom's YouTube videos helps, I find. In addition, there is a treasure trove of threads here with expanded concepts and information.
These are books written for the being level, not the intellectual level. I've read the books three times over now, and some sections even more than that. Each time the books have seemed completely different to me, and I plan to read them again eventually.
Get your ego in check and try again.
