I would strongly suggest that before anybody tries out any Grimoires at all - no matter what type - to get thoroughly grounded in the basics first, and will add a quote here from the late John Milo DuQuette's superb 'Enochian Vision Magick' where he states the following:
First the magician becomes master of the pentagram and a full citizen of the world of the five elements of the microcosmic universe. By repeated performances of the pentagram rituals & meditations, the magician's psyche becomes balanced & accustomed to the world of the four directional winds, the four elements and the corresponding magickal weapons: the wand, cup, sword & disk.
Once the elemental (microcosmic) universe is mastered, the magician then moves on to the next step in the attunement process by mastering rituals of the hexagram. Here the magicians point of reference is enlarged as his or her consciousness and identity is obliged to expand from the microcosmic world of the elements to the macrocosmic greater world - the world characterized by the sun orbited by the planets and surrounded by the belt of the zodiac.
This is very basic stuff, but it illustrates how rituals enable the ceremonial magician to externalize internal processes and undergo self transformation. Would-be magicians who attempt more advanced work without being adjusted by these early attunements are ill prepared to understand or properly absorb what is happening to them within the context of the progressively higher magickal environments in which they presumptuously wish to operate. It is true that some magicians may recieve seemingly dramatic and noteworthy effects from such premature efforts, but seeds of promise cannot long take root in soil that is not properly prepared or that is too shallow.
The above may read as if it is attempting to teach granny how to suck eggs, but I cannot stress long or often enough of the importance of doing the groundwork first - tedious though it might feel to the more impatient of us these preliminary steps should not be avoided, glosseds over or otherwise skipped and/or ignored & we ignore advice such as this to our own perils.
Why have I posted this, when it could be argued that I am simply avoiding the OP's original question? Simply because it matters not one iota what I think, or what I use, or what I believe to be 'the Grimoire that delivers' as I am not the OP, and my mind works in a different way - is not Every Man & Every Woman a Star, after all? (Not that I would consider myself as a Thelemite, you understand, but that the sentence as stated applies across the board along with the even more sublime (and even simpler) statement that magick is 'the science & art of causing change to occur in conformity with Will' - accepting the truth of this doesn't make the person who understand the truth of this a Thelemite any more than accepting the truth of 'Do unto others as you would have them do unto you' makes you a Christian. Some truths are, after all, universal.
@ Kalajadu777, in summary before you move to any grimoire (or indeed anything remotely similar) please, I beg you, master the basics first.
