The Leaf of Immortality

Aaron Cheak, PhD

19 MARCH 2017

WHAT HAPPENS WHEN you study comparative religion, philosophy, and esotericism for fifteen years and then take heroic doses of entheogens? In many respects, this book is a long answer to that question. The short answer is: The floodgates open. The dried riverbeds of academic learning become inundated with raw, living, divine experience.

In this short but zesty volume, Dr Cheak explores the intersection of Nordic theurgy, Hermetic philosophy, and cunning linguistics to reveal a uniquely alchemical lesson: how to play with poison in order to find its hidden gift.

Through richly layered references to the sinister theologies of Loki, Hermes, and Seth-Typhon, Cheak shows how divine gnosis ultimately dissolves the duality between our inner and outer worlds. What we call “gods”, he remarks, “are living principles that continue to incarnate both in us and in the world around us in ways that elude rigidly theistic understandings”.
