I have been able to move the Assemblage Point with the help of a friend who is a "Sensitive" and who can visualise the Point and where exactly it needs to be moved to. (She is a healer who uses several methods and wasn't really impressed with this one.)
It was a short-term fix, however. She was kind enough to work with me several times but it never stayed "fixed" nor did I notice any changes.
There are other, better, healing methods like "The Healing Code" by Loyd/Johnson/Eble - an amazing process of emotional clearing. There are hundreds of personal successes including physical healings, listed in the reviews on Amazon.com.
