Hi 
I agree with the people who say that the Guradian Daimon is just another word for the Guardian Angel 
. Different cultures have different terms for these beings. For example, the Vikings apparently called them Fylgjur, which supposedly translates to “following” or “accompanying” spirits.
Does anyone know of a ritual beyond those recommended in the book of Abramelin, which I consider somewhat complex so to speak, an easier ritual to do in which I can confirm the name of my protective daimon or demon?
In this forum, I’ve posted a detailed guide on why and how to make contact, where I link to a few different approaches, and present my own idea. I hope it helps
