I just finished Numen Naturae: The Magician's Wand, a collection of essays edited by Casandra Johns and put out last year through House of Hands, which is a collection of essays on the seemingly idiosyncratically specific, but very illuminating topic of the the archetype of the Magician in the tarot, the plant spirit of Yarrow, and the overlap between the two. I've always been fascinated by the Magician, and I have been working a lot with Yarrow lately, so naturally I found the book quite enlightening. A great deal of the book deals only with examinations of the Magus (within and outside of the tarot), but it does come around in the end and return to the topic of yarrow, and makes a strong case for the connection between the two. It was really a lovely read, delving as deeply as it did, and from so many perspectives, into a topic that was at once ultra-specific and totally universal in its scope. There's Jungian perspectives, animist meditations, and more, and even some practical magic that can be followed contained herein. Reading it was really an initiatory experience for me, and I can't recommend this book highly enough to anyone who wants to better understand what it is to work magic, or who works with the tarot, and especially to anyone who works with yarrow or regards Yarrow as a teacher plant. 10/10
PS: I guess this is supposed to be the first installment in a series that will pair each trump in the major arcana with a plant teacher; I think there's already another one out that pairs the Tower with Devil's Club.
