At urthgame.com you can find an explanation of the science behind the magic of the prosperity orbs (such as Cancer Killer, Chakra Cleanse and the Clear Light Orb) and how to get started running orbs.
I have talked about this in several posts and have been working with the orbs and doing readings for years. They are brilliant tools and you may find them helpful especially if you are a professional care provider such as a nurse, clinician, therapist or if you are a family caregiver trying to help your loved one.
