I have been asked a few times over how to properly do an evocation. Well, I just want to share right now that one big one is to be clean before hand. You should not summon something pure if you yourself are not pure. Yes it is possible, but any magician will tell you that at times, some evocations seem “better connected” then others. I took notice that if I would do my salt water/ banishing ritual, just before any evocation, my clean skin, body, spirit, and soul were MUCH more absorbent to the vibrations around me. Just one piece of advise that works every time and very well for me. Not sure about others, but everyone should give it a try in my opinion.
