T. M. Sullivan finished reading Alchemical Divination by Ralph Metzner
A flower of the post-60s cosmologies of spirituality: a broad definition of all divination (regardless of method) as fundamentally "intuition" from the self, a Jungian sense of individuation as the goal of divination, combined with a Michael Harner-style core shamanic animism that blends between the psychological and the literal.
Concretely, this book proposes several rituals, a "fire" yoga, and methods for divination for looking at the past, present, and future, trying to pass across method. I don't think Metzner is ever truly able to thread the needle he wants to thread between the psychological approach and the animistic approach, and the two in contrast can be jarring (why would I summon in support from power animals if this comes from me? why would I see divination as accessing myself if I bring in spirits? etc.), but its one of the more coherently put together attempts to do so, although perhaps showing where the limits of such syncretisms are.
