Thanks for the clarification on "devil". I'd had a funny reaction to the word.

Ok... Questions: I recognize that anger has more mobilizing power than fear, but A. How do you recommend performing the technique of switching emotions?
B. If there is such a way to simply switch from one emotion to another, why choose anger which is also negative and physiologically/spiritually disturbing rather than courage or serenity?
C. (more of a comment) I've found for me that the emotion of anger carries and leads a bundles of fear. If I'm mad at someone/something, I want to destroy him/her/it, which brings on the fear that I can't, that I lose, that I'm wrong, that I'm evil, etc.

I have several processes that seem to work for now in which I recognize the feeling I'm having and where it's rooted and systematically release it, which changes my experience. I also meditate, chant, and try to surround myself with spiritually oriented people with some regularity to stay buoyant, in form anyway. when I'm in pain, it doesn't seem like anything's improved, but the spiritual world doesn't work in a linear fashion. And externally, there are a lot of improvements to demonstrate the pain's all in my head.
