I've heard people say that the best spells to work with are your own. I read a spell that helps create other spells on the site but can't find it anymore. So I need to know how to create my own spell and any practices that will put power into it that'll make it work. I don't have that many resources. The only thing I can get a hold of are candles but only in a few colors. So does anybody know what to do to make your own spells and harness power into them? Thanks and blessed be.
