First Summoning Options

Two nights ago, I summoned my first entity. I didn't use a circle, or any other kind of protection. I just got into a trance, and I asked the nearest friendly entity to come forth. I felt him here, and I asked him his name. I'm not sure if it was my imagination, but
he told me his name was Apophis in a monster-ish kind of voice. I don't think it was my imagination... because if it was, I would've probably picked a name I could relate to... I've never heard of Apophis. Anyway, I asked him to leave, and I thought he did, until I got in bed to go to sleep, and I felt him behind me. He was touching my back or something. I banished him with the Solar Cross, and it worked. The end...

Greetings Alric Thomas!
I don't agree with your assessment. 'Priests of old aeons' intrigue me. What time frame/ethnos are these Priests? (BTW, Priests and Magicians can be looked at separately) You fail to mention that though a circle wasn't used, some other device was used. The protective device in Sumeria was square. I cannot say about the ancient magical practices other than what I've read and even then the sources can be suspect. To practice evocation without protection is foolhardy. Personal power does play a role. The use of tools in magic are primarily used for focus of intent and/or symbols representing facets of the magician or of the working.
Perhaps you'd care to discuss the aftermath of a magical working when/if the mage fails his/her 'true test of power'? Would you jump into a shark tank without protection? Until you are on firm ground it is best to use some time honored methods...which, BTW, are themselves thousand(s) of years old. We understand that a circle needn't be 7-9' in diameter scribed with Hebrew characters. It can be rather small and drawn into the Astral light...without an athame or black handled knife or boline, etc.
I am very interested to hear your explanation of 'bloodline' in regards to all this. I'm always interested in learning new things.
Pazuzu huh? Are you reading the Simon Necronomicon? or Kenneth Grants books (OTO)? From my understanding Pazuzu is a Pestilence demon and not particularily nice. I am very interested in anything Sumerian/Babylonian.
