I decided to write a short review on this book after purchasing it.
It is a practical book with a NAP style ritual framework.
I purchased it (the digital version) by curiosity reading that he has inspired from the 6&7 BoM.
I tried a few ritual and i felt every time the energy of the spirit i called.
The most powerful was arch.Raphael ,when i asked to work on myself.
I noticed the the seal of are some kind of a mix between the ones found in heptameron and the BoM.Some of the shem seal are altered too .
At the angel of the 42 names an admitting word is used like in MG.
Regarding to the ritual itself there is a powerful resemblance with one of Adam Blackthorn s book.The same word is used in the preparatory ritual as in this one between others.
While i was working with the seal s i realized that i got a good reaction only by looking at the seal calling the angel and asking it s assistance.
My conclusion would be that if your a NAP practitioner you might find this book useful but if you re a traditionalist don t bother ,thou you might find it usefull the area of influence of angels of virtues or the angels of the thrones.
Wish u a pleasant reading
