Hi Atreiu,
No longer about the neck so much as alternate healing and the enormous link between mind and body and how experiences and perception can have a profound impact upon physical functioning and vise versa. Mark is a witch doctor :) and I dont have a great attention span and float off on tangents so it seems to have flowed off on to more generalised ideas. I hope you are finding the chakra stuff good, I was embarassed at first because it sounds a bit hippy but its good stuff. If you dont mind me asking what chakra stuff have you done. Have you done any of the colour work or any of the therapy? or is it just an awareness of possible causes that has helped? I found that just having an awareness of what might be behind the problem was enough for me to change my mental attitude and see some results.
The natives not seeing the boats is fascinating, I love learning about new stuff and am one of those people who pulls stuff apart to see how it works, and sticks my finger against a wet paint sign just to check it is wet. I once heard that it was incredibly hard to shoot yourself in the head with a rifle so I bought a replica to see if there is a way (you need flexible legs and you need to be careful or your toe gets stuck) not that I am in any way suicidal but just cause I wanted to know. Mark is a fount of information about stuff I dont know much about or have never heard of so I think of it as mental exercise reading his posts.
PS. Have you heard of the ignobal prize? It is handed out around the same time as the Nobel prize and it is given to a researcher who does the most useless or pointless research. I always read about the contenders. One year a guy won for his study on belly-button lint. He conclusively proved that no-matter the race or environment of the person everyone produces blue lint. Some of them are hysterical but you learn about things that you never thought about (or cared to know about LOL) Working your brain and learning new things is meant to have an impact upon brain degeneration and the onset of dementia, so its all about taking proactive measures to counteract the brain damage from being hit in the head :)
