An odd and slightly disjointed collection of material pertaining to the A A and Crowley's esoteric philosophy. No doubt the unabridged Equinox experience would be much richer, but as a dilettante in this subject I could not justify the expense.
The preface by Israel Regardie contextualises Gems from the Equinox well, and Section I gives a fascinating insight into the inner workings of the A A. Section II contains the infamous Book of the Law, which is probably the single most important thing Crowley wrote (or rather didn't write, so he claims). As a work of poetry and 20th century mythology, it's worth checking out.
Section III - on Yoga - was the most rewarding for me personally. Having never studied it independently, I can't say how much is Crowley's idiosyncratic interpretation, but I found it very compelling. Essentially formulae for a series of exercises, meditations, and thought experiments, I felt like I was really understanding something profound here. Much like Prometheus Rising, these 'rituals' are designed to break you out of your daily programming and see things from a new perspective. It seemed to me that Crowley acknowledged there are no gods or magic really, only the mind and the metaphors we can use to channel personal fulfillment (the Great Work). My understanding of his biography tells me this might be counter to his intentions, but nevertheless I took that interpretation.
Sections IV, V and most of VI (Magick, Sex Magick, and Miscellania) were lost on me. I found a lot of the content pretty impenetrable, and I concede that's down to my own lack of erudition. I will return to these again after reading more occult philosophy. One exception was The Master of the Temple - the published diary of an A A probationer undergoing his spiritual journey. This was very readable and illuminating; probably my favourite single chapter in Gems.
Section VII's overall relevance to the book, which is structured to be a manual for spiritual attainment, is questionable. Consisting of 250 pages of book reviews, it's certainly good fun to read Crowley et al ripping the shit out of other writers - he is what David Bowie would call a 'Queen Bitch' - but it sticks out like a sore thumb and can get tedious. I suppose Regardie wanted to give a flavour of the unabridged Equinox. In that case, why not include the short stories too?
Gems from the Equinox is not a book to be read from cover to cover. Its various sections will hold different appeal at different times. Some need be read only once, others can be endlessly revisited. A mixed bag, but one I'm glad to finally have on the shelf.
