Paul seems to use TFT for this type of thing- if you check out his site-
Paul McKenna McKenna USA Home look on the left hand side for video techniques- and that will give you a starting point-
From a different stand point- I would suggest doing a google video search for DR. Bruce Lipton as some kind sole as posted his Biology of belief lecture- which would give you a insight into how beliefs create change at the level of biology- his book by the same name would be worth a read as well.
