I see that no one has mentioned depossession. Personally, I find depossession to be the most powerful shamanic intervention for my patients. (I am a psychiatrist.) When I learned to do depossession (from Betsy Bergstrom, www.betsybergstrom.com
), I was relieved of the soul of a man who committed suicide and then attached to me because "he was sad and lonely, like me." After the procedure, I was completely free of depression. Amazing. My wife wanted to know what happened to me when I got home. She said: "you are not Eeyore any more."
