The Devil's Tome: A Book of Modern Satanic Ritual explores non-theistic satanic ritual as a means for healing, empowerment, and community building. It brings light to what is often a hidden and misunderstood practice and provides insight into how to cultivate your own personal power through Satanism. Shiva, a long-time leader within The Satanic Temple, discusses her own 'journey to the underworld,' the scientific case for ritual, and how to create your own Satanic ritual practice. Shiva includes a collection of Satanic rituals for the solo practitioner as well as group rituals, which include photographs, scripts, and background on rituals done at The Satanic Temple Salem. The book features a foreword and illustrations by co-founder of The Satanic Temple Lucien Greaves and illustrations by Lex Corey.
