My question is why would anyone want to deal with this stuff. If you're relying on this silly material, you clearly don't have the faintest idea what you're doing - in all likelihood, you'll just end up "summoning" lots of random mischievous spirits who'll be trying to have fun at your expense in weird and surprising ways until you finally learn how to banish them properly. There are plenty of other ways to get started with occult and magick that don't have this particular pitfall!
