I want to learn white magic so I could do some good in the world where would be a good place to start. The only thing I really know at this point is some minor demonology. Also I was wondering if white magic could eradicate a source of evil example demons.
There is no real color to magic, just intent. If you wish to do good things, perhaps learn about healing. The first place to start on any path should be the basics. Meditation, grounding, centering, visualization. There are quite a few posts in the forums. I do not believe "Evil" cannot be eradicated, for the universe requires balance.
