Since I finished the Wand and the Table of Practice used in Frater R. O.'s "Modern Angelic Grimoire", I've performed two evocations.
The first was of Uriel, Archangel of the Elemental Sphere of Earth. With the initiation and integration of the elemental spheres, I'm mostly going off of very educated guesswork based on the Modern Angelic Grimoire (hereafter referred to as the MAG) and Frater R.O.'s writings on his blog. There was a change to the lamen that I made, something I had to leave out until a later time. It's cases like this where I really wish I could afford R.O.'s Black Work course, because I'm really diggin' 'dis neo-platonic stuff!
The procedure for evoking spirits via the system in the MAG is very simple and straightforward. Surprisingly, after calling Uriel, I noticed a change around me. Things were...closer? Not hotter or smothering...but it's more like I felt really, really physical. My senses were not enhanced, but it felt like everything was more solid. Even the air seemed to take on a weightier, solid feel. The forms of everything around me was more distinct.
As for Uriel himself (itself? I take a Neil Gaiman view on angels), I found him rather amenable, not dark like I've heard of him before. He was frank and down-to-earth...all the things I would expect of a spirit related to elemental earth. Unfortunately, my scrying skills are not completely up to par. After I asked Uriel to give me initiation and integration of elemental earth, there was some ambiguity in my perception although he did seem to agree to it.
When I thanked and dismissed Uriel, as soon as I was done, another change happened. That close, weighty feeling dispersed, although the sensual perception remained for a little bit. Since I did that evocation, there have been some earth-related challenges that have come my way, but I knew they were coming before the evocation, so I don't think they were a side-effect. However, I have been good at dealing with them, and have had tiny bits of help along the way.
The other evocation was of my personal Genius. Through the "Genius and Evil Daimon Calculator" on Frater Acher's downloads page, I found out the likely name of mine. Using this and instructions for conjuring spirits on R.O.'s blog, I constructed the lamen, but otherwise performed the evocation as given in the MAG. I can't remember some of the conversation, but my Genius did appear. I ended up getting a sigil from it to place on the lamen (which I forgot to do with Uriel).
After I requested that it facilitate the knowledge and conversation of my HGA, it told me to conjure it again in 3 days. So, come Friday, that's what I'll be doing!
