Reading the Octavo is kind of a rehash of some of Peter Carroll's other ideas, but at the same time is a clear extension of where he has developed those ideas to a level of sophistication that mathematically proves his points. The Octavo isn't an easy read, and I recommend doing some research into the technical jargon that Carroll uses, but underneath the jargon the reader will find a concise explanation of specific magical concepts and how those magical concepts fit into our particular universe ...more

Shelves: magick
I loved this book. It's a really exciting read and feels like someone dropping an alka-seltzer into your brain because it triggers off so many ideas and plans. Peter Carroll for those who don't know is a Chaos Magick bigwig who has written some key texts for those of us who like to prance around, make silly noises and ritually interact with the (rotating, hypercuboid) universe. Chaos Magick for those that don't know is the collision between Aleister Crowley, cyberpunk and post-material informati ...more

Recommends it for: Occultists
A few tenets from this book have influenced my thinking, and Carroll is without a doubt one of the most influential thinkers and writers in modern "occult" (an outdated term) history. I even learned a little bit about physics.

That said, I found this book to be kind of boring and dry, perhaps even willfully obscure. And I'm no mathematician, but my bullshit-o-meter definitely rings at all the passages about the equations and physics of magical influence.

Considering that Carroll seems a bit of a p

Ever world has a secret grimoire that contains the magical secrets of the world. For the Disc world, Terry Pratchett’s creation, that Grimoire is called the Octavo. Thus far Earth’s or should I say roundworld’s grimoire is yet to be be discovered. In Discworld it is buried and guarded. Roundworld’s Grimoire has only been revealed in fractured or fragmented form.

Roundworld is much different from Discworld in many ways. To name but a few, Discworld rests on the back of a turtle and is supported by

“Drugs have a long history of use in magic in various cultures, and usually in the context of either ecstatic communal rituals or in personal vision quests. However compared to people in simple pastoral tribal situations most people in developed countries now live in a perpetual state of mental hyperactivity with overactive imaginations anyway, so throwing drugs in on top of this usually just leads to confusion and a further loss of focus.

Plus as the real Shamans say, if you really do succeed in opening a door with a drug it will thereafter open at will and most such substances give all they will ever give on the first attempt.”
“[A] competent magician should have the ability to stand still at a bus stop with closed eyes and have the entire universe disappear apart from a single blazing visualised sigil or muttered spell.” 3 likes
