This book by Andrew Chumbley and others is a remarkable limited edition hardcover that offers an interesting exploration of esoteric themes related to the figure of Cain.
As an exoteric representation of their praxis, it presents a collection of psalms, prayers, and invocations that build upon Cain as a figure of devotion. The rituals range the gambit from simple to complex and are very different from other books that explore Qayin as a source of inspiration.
The book's production quality matches the depth of its content, featuring high-grade paper, intricate illustrations, and a sturdy binding that befits its status as a collector's item.
