Find the book "Kundalini Equation" by Steven Barnes. It's out of print but not hard to find at all. It is fiction but a lot of it jives with other information i've read on kundalini meditation/work. If nothing else, it's a helluva read. Kinda scary and maybe a cautionary statement on the practice.
"George never did wake up. And, even all that talking didn't make death any easier...at least not for us. Maybe, in the end, all you can really hope for is that your last thought is a nice one...even if it's just about the taste of a nice cold beer."
"If you find the right balance between desperation and fear you can make people believe anything"
"Is enlightenment even possible? Or, did I drive by it like a missed exit?"
It's simpler than you think.
I could be completely wrong"
