Say you cursed someone you do not have communication with. How do you know that the curse worked? I read somewhere that you will know it somehow (thru news from other people or other means) but I can’t remember where I read it.
Welcome @cassiopeia I see you joined us back in August but this is your first post. Please make an introduction in the NEW MAGICIAN AND INTRODUCTIONS area, and tell us about yourself and any experience you have in magick. It is a rule of this forum.
You decide beforehand what the desired outcome is. You then perform the curse whilst being in the mindset of a god. You are in that moment the god of your Universe, your reality. The person you curse is at that moment a part of your reality. You must exhaust your desire and the pain you feel when performing the curse. You must walk away knowing that the curse is working, that it has worked. Trust is key.
You don’t need external evidence. That’s for people who don’t trust in themselves as the god of their Universes.
