I was thinking how do you use a doll or a poppet.
I am actually still new and I am just reading the articles all around here on how to start doing spells and even casting them. Then I am browsing the spells in this site. There were some spells that need dummies, dolls or poppets. Is it the same as voodoo dolls? Sorry, i havent been reaching those kinds of learning as of yet. But I am really curious about it. So I hope you guys will help me 😊.
Also, do you need to charge your doll or whatever you call it with your energy or spell or a prayer before you use it or while making it? Any answer will be a big help! Thank you!
