Hi Mu-Shen,
If you want to jump over to the "Healers Who Share" forum you can find more info regarding SEM there. That was the forum where all the SEM talk first started.
You can go back and read some of the post and find alot of info.
If you visit http://www.sourceenergymedicine.com
you can watch 2 short videos and read some parts of the book. It might take about 30-45 minutes to review. It explains it pretty good.
I understand what you say about cost in buying the book but you can get the e-book and labels to make the water from .50 cents to $49.95 The website has coupons and you can use any of the codes for the price you feel that you can afford.
It's very inexpensive to do this protocol. Let us know what you do and come on over the HWS forum this one is now closed..
Blessings, Raider
