I had a twitter mutual that was into that sort of stuff, I remember him recommending a book I never read, named something like mind protection, spirit defence or something
no idea which author it was, tried googling a bunch but couldn't find anything
Dion Fortune's Psychic Self-Defence? No idea if there's a connection with anarchism but it's an older book that gets recced a lot
I feel like that should be the one, a contemporary to crowley and her wiki page is in my history, so I guess that's it, thanks
