I used this method for about 6-8 months maybe a dozen or so times a month. The results I created for myself are something that I really don't have words to describe.
In my opinion, this works well as a thing to do by yourself. The book gives more than enough instruction and helpful hints.
I was able to create a MASSIVE shift(s) (for the better) in the quality of my experience.
Very high quality.
1) You identify a behavior/feeling/response you want to change
2) You find a 'part' of yourself that is responsible for the behavior/feeling/response
3) You recognize that the part actually has a positive purpose and ultimately wants to do you good or protect you
4) You make peace with the part and become friends with it
5) You uncover the part's purpose, probably after passing through several layers of intent - you get to the 'core'
6) You ask the part to keep its purpose (which is positive) and change the behavior/feeling/response associated with it, reaching the same results by another, more ecological behavior/feeling/response
7) After the procedure things will begin to change, even though you may not be immediately aware or it - your unconscious mind may not provide you with that knowledge.
In 1997 I had to make this big change in my life and I was not sure how to begin. Fortunately I was lucky to participate in a Core Transformation workshop given by Connirae and Tamara Andreas in Denver. It was an incredible experience that helped me a lot, even though only years later I had enough perspective to appreciate all its influence on my life. The effect, I now believe, was that I came back from the workshop feeling much stronger and sure of myself, with all my internal parts aligned.
You may choose to take the Core Transformation workshop before or after reading this book. This book can be just a book or a powerful change tool depending on how you use it. You can do the exercises yourself or (better) with the help of a partner.
I hope my account helps and that you use this book to make the changes you want in your life.
