OK so... what warning should it have had that would've prepared you for it?
Maybe there was some warning in the book, but I was young and keen enough that I would've just heeded that.
Even the author of the books father is a renowned meditation teacher, I'm sure that was helpful.
I already subscribed to the idea of the self and identity being independent and constructs. A lot of reflection around that and physics in younger years maybe helped.
Some knowledge of physics would help for sure. From memory, there is some mention of psychics it in the book?
