Liber Sigil-A-IAF by Aion 131, the 2010 library edition hardcover from Waning Moon Publications, is part of the collection at the Reading Room.

“A modern grimoire of New Aeon Magick that consists of a series of Major Sigils crafted as ritually manifested automatic drawings along with arcane writings ‘pertaining’ to them. Thelemic at it’s core, this work is empowered by the energies of the current Aeon of HORUS but is also deeply rooted in other Aeonic energies, most specifically the magickal current of MAAT: the aeon to come which is manifesting here and now as well. Together they form The Double Current. The book is organized by the ‘natures of the spirits manifest’ into five sections that fall under the major Thelemic/Aeonic Archetypes NU, HAD, HERU, MAAT and the Shadow which is PAN. They are representations of abstract laws, powers, and conglomerates of symbols with uniting elements that can be activated and used to access deep strata of the inner-being. They are not to be intellectualized. The Grimoire is both a work of art magick as well as a tool that can be used to help accomplish The Great Work by the open minded New Aeon Adept with Love & Will.” [via]
