This is a pioneering work, fusing Shamanic entheogens with the Qliphothic Arts. The approach is unlike anything I have ever seen, and I cannot stop reading. This grimoire coalesces the Left-Hand Qliphothic system and the ways of ancient Shamanism, revamped through the infernal spirit emanating from Edgar himself. As if that wasn’t enough, E.A. contributed his extensive piece, wherein I was fascinated by his thirteen entheogenic doorways that you can open by consuming/taking them, and thus you become the gateway. The more I read, the more I truly appreciate the years of effort, experimentation, and Shamanic-Qliphothic gnosis. Herbarium Diabolicum & The Poison Path is a great read and I definitely recommend it.
