The Arbatel is a medieval treatise on how to live in harmony, ease, and intimacy with the energies of the Multiverse. Behind the Christian piety is a more ancient, Pythagoric and Neoplatonic spiritual paradigm that views the world as a multilayered place full of spiritual beings: some elemental, some celestial, some angelic, and some demi-godlike, archonic, or patriarchal.
Rather than being an incomplete book, it may be that all of the themes described above are really secretly layered into the book and waiting to be discovered like buried treasure. That is, the Arbatel may be an example of medieval steganography in which messages are encrypted and buried within "cover texts."
I posted the first month of my experiences on a blog.The posts garnered some interest, and I found myself being invited to join three other people in a group magical working related to the Arbatel. The first phase of this Working took place in May and the second in July 2010.
