I did the practioner training in Emotrance 2 years ago. In some ways it's better than EFT, in many ways it's not. People who are not very auditory prefer Emotrance as it's very kinesthetic and visual. One person I worked with using EFT got nowhere until I tried Emotrance with her, but generally, EFT is a superior model in my opinion. Some therapists I know love emotrance becasue they themselves are more visual.
I have a 15 page word document/guide about it, so it's not necessary to buy the book. Sylvia Hartman is a great writer but a very odd person! LOL, you would have to meet her to know what I mean.
I can email you the full document. Send your email to my email me link.
