the first you should work on after doing your meditationand rituals thenfocus andground and center,do your lesser banishing then, cast your circle call the quaters ect get my drift? casting spells isnt just casting it is a lot of things combined to work up power ect, and i was told the best and safest for a beginner is power spells you get safe practice while building it up ok message me if ya need
So without having any prior knowledge of what a bat is, how the bases are lined up, where to run, or how to score, you want to just jump into a championship baseball game?
Please do not feel like I am coming down hard on you. I use this analogy with all new to the craft.
But the fact still remains, there are basic you need to learn before spell casting. Meditation, power sources, energy work, history. Are you just practicing magick or actually actually choosing a religion? Who is/are the deities who would be involved? If you do not have a foundation on which the house is built, it will fall apart in the first storm that comes.
A great place to start is Newbie central.
