Angelic Magick

"The visualizations here draw their imagery from classical grimoires and Qabalistic philosophy. Plus, they have a specific and useful goal. Each visualization takes you on a journey into the symbolic realm of an archangel, where you are introduced to the entity's sigils and symbols and other sacred imagery before encountering the archangel himself. Each visualization builds upon those before it, until the aspirant has been led through the seven circles of heaven and has established a personal link to the archangel that governs each one. At the end, the aspirant will have learned to recognize the images, seals and symbols they will encounter in the Solomonic and other advanced systems of angel summoning.
Such guided visualizations are certainly absent from the medieval texts about angels. So, why should I urge anyone who wishes to work with angels - even Solomonic practitioners - to follow the instructions in this book? Simply put, this book is based upon the same principle I described above: safely establishing first contact. It accomplishes this without resort to the full-fledged summoning ceremonies intended to call the angel down to the physical plane - an advanced practice the grimoires tend to jump into without preamble.
This book even includes simple rituals by which you can submit petitions to the archangels in times of need - and these rituals are not entirely removed from the methods of the grimoires. Therefore, working through the steps outlined in this book can serve as a wonderful bridge between "square one" and the fully adept practices of angelic summoning."
