I once had a friend who invented a device that plugs into the wall. What you do is create 2 identical Sigils (a hand drawn symbol or foci used for a desired effect) and put one against the device and the other on your person. I did this and put it against my naval and felt an immediate influx of power but it was sort of strange, it felt forced like a short-cut (maybe creepy is a good word). Has anyone else attempted to plug their soul into an outlet?
It's neat but I wouldn't suggest using it as your main method.
