Negative . . .
...and positive.
Your comments set my mind to wonder, recalling a fellow soldier I had met in Panama. He was negatively charged, relatvely speaking. He was wearing an electric analog watch, backed with a simple strip of black electrician's tape. He removed the tape and put the watch back on, and the hands ran in reverse. Replacing the strip of tape corrected this.
...But that's a bit off the initial topic. Sorry.
Anyway, I do not believe 'good' and 'evil' are energies, but perceptions -- interpretations. We are, therfore, limited in our personal understanding of them.
