First of all I’d like to start by pointing out the fact that BALG is a very tight and supportive community, however I advise you to introduce yourself so people will know that you have good intentions.
It’s one of the rules, please read them.
Regarding to this topic, I suggest reading a lot before trying to do anything involving Magick.
I recommend getting a copy of Summoning Spirits by Konstantinos, it will explain how spirits work, how to invocate/evocate and much more, believe me when I say that it will help you a lot.
