I recently read Doktor Snake’s Voodoo spellbook (available in my school library, donated by someone who a building is named after, I find this awesome). I’d recommend it even for people who don’t care to practice Voodoo or hoodoo because it gives interesting information and was pretty nicely written. It’s not just a spellbook, it also talks about some stories and the author’s experiences. Hoodoo, Voodoo, and Conjure: A Handbook is also pretty good for people who, like me, are sick of hearing about Voodoo but knowing nothing about it. I got it from interlibrary loan.
One of the bits Doktor Snake’s Voodoo spellbook spoke of was Robert Johnson, who allegedly sold his soul to the devil. It talked about how the “devil” at the crossroads was initially an African God who acted as a way for mortals to communicate with the Gods. This God was turned into “the devil” by white missionaries who came to Africa. So the term “devil” doesn’t have the same connotations for people who believe in Voodoo as it does for most people, and selling your soul to him isn’t as horrible as it might be to Satan.
I’m not even sure if you are “selling your soul” to him, it seems more like you’re making an agreement that you get something you want and give up most of your life in exchange, I’m not sure if there’s anything about what happens to it afterwards. There are people who would find 10 years of artistic genius well worth never living to see 50, but if the God got to keep your soul afterwards I don’t see why he couldn’t wait a few more decades to get it. But you might be so I don’t know, I’m clearly not an expert here.
