For some people this may not be "magickal" information but for other it might be. I am only going to give you a hint/warning that not only had I learn but would do you wonders.
"Read the bible."
Yes, you hear me right, the bible and no I am not a bible thumper or another person here to save your souls cause I am not.
It (kind of) pains me to admit it but the bible will sure help you a lot in your occult studies. It is mention a lot in some particular things as well in some books it is a reference. Not only will it be a reliever but when you hear people talking about it (yes some magickal practitioner does talk about the bible as well myth behind it) you will be well inform instead feeling out of place. Believe me when I say that is not fun.
This is from a person who keeps telling herself that she would never read the bible. Six years later she reads the damn bible. Karma bit her in the arse as well the Gods who mocked her.
Just thought to mention that.
Also this is my opinion not many people will agree with me and I am completely fine with that.
