Abramelin The Mage, Questions... Options

Just read the first two books of "Abramelin the Mage".
Amazing books.

After reading these books I feel completely lost and like all thse time and reading of other magick books have been in vane.

These books teaches with authority just like in the bible how to be very careful with the wrong magical books such as making pentacles or invoking certain spirits or shouting strange names out loud, and believe in other gods or writing strange patterns or names.

As the author of the book "Abraham" during his journey to find his mentor "Abramelin" saw with his own eyes all the false and treachery false arts (whom looked correct but in reality where not).

Then in the second book we have many pages explaining how retire and prepare the altar area for the angels and having certain items and oils and such and doing fasting and such... during 6 months and be loyal to the sabbath days. Until the holy guardian angel manifest it's presence unto you.

One never calls the archangels or ever do any of the LBRP or BRH or any others as mentioned in most of the magickal books.
Strangest part is how the "Golden Dawn" used these books for their studies and yet they seem to follow other teachings.

I feel a little confused and concerned with everything now, I hope one of you can help me out here...

Good morning everyone.
Forgive me for speaking, making a strictly personal thought.
I believe that when we read these ancient texts, and especially the grimori, we must also identify himself, the thought of the time in which it was written.
This will allow, first to understand, that no ancient text such as the Bible, will come to us, perfectly intact in its concepts, but that each manuense, who rewrote the text, have also made conceptual changes, according to their I think.
It is also important to see the text, in the context in which it was written, then beliefs, religion, and the degree of human evolutionary time.
In the writings of Abramil, is the predominant conception of the supernatural, which fully describes, as irrefutable concept of sacrifice and removal of man's desires, in order to strive for maximum purification.
The times are very long, this is because the adept, will reach the maximum belief in what they want to achieve, and what it evokes for you to help him in his goals. In order to reach such a state of conviction must abnegare himself and strictly stick to what needs to be done, without any distraction.
In this way, when it is ready to operate, and will operate, will get what you are prepared.
That's because anything is possible if you truly believe in doi us.
All this is expressed in a totalitarian, as if the truth was that, and everything else just falzità ideological.
Even this way of presenting serves to make the adept, depending on his views.
Who wrote these texts communicator certainly was a great time, as well as being very intelligent person.
But I am convinced that these texts had its own weight only for those times where superstitions and beliefs, lived in ideological and religious speculation.
MI hope that today, the evolution of man differs much from that, considered by Abramil.
So I think, to go beyond these texts, though fascinating and interesting.
Otherwise there would be no evolution of man to ONE.
