hey there,is there any spells that the person we want to should read it him/herself?
i mean i want to for example curse someone,i write him the spell and he himslef will read it without knowing it?
or i want someone to heal from (x) and i just write it somewhere and she will read it like an usual tezt and the spell will work?
someone told me about this but she heard it from someone else...
if something like this exits,can you tell me which ones and other details about it?thank you :]
