"Countless books teach you the mechanics of magic, but very few teach how to develop your occult mental abilities so that you can perform magic effectively.
Before you perform spells and rituals, you need to develop your mind's muscles. Without mental preparation, you'll just go through the motions without any results. Everyone, regardless of experience or traditions, can learn from these exercises and gain the mental focus to make your magic much more effective.
Donald Tyson provides twelve chapters that each cover a different topic or type of occult skill—such as concentration, meditation, scrying, astral travel, and aura manipulation—and why it is necessary for better magic. Within each chapter, you'll find ten exercises to help develop the corresponding topic or skill. Magic comes from the self, and you need to work on yourself before you can cast spells that work. This book has everything you need to do serious magic."
"Anyone familiar with H. P. Lovecraft's work knows of the Necronomicon, the black magic grimoire he invented as a literary prop in his classic horror stories. There have been several attempts at creating this text, yet none stand up to Lovecraft's own descriptions of the Necronomicon . . . until now. Fans of Lovecraftian magic and occult fiction will delight in Donald Tyson's Necronomicon, based purely within Lovecraft's own fictional universe, the Cthulhu Mythos.
This grimoire traces the wanderings of Abdul Alhazred, a necromancer of Yemen, on his search for arcane wisdom and magic. Alhazred's magical adventures lead him to the Arabian desert, the lost city of Irem, ruins of Babylon, lands of the Old Ones, and Damascus, where he encounters a variety of strange creatures and accrues necromantic secrets."
