Unity Uttermost Showed! offers a selection of papers from the seventh biennial National Ordo Templi Orientis Conference (NOTOCON) of the United States Grand Lodge of O. T. O., held in the Valley of Seattle, Washington, in 2009 EV. The papers cover diverse topics including Enochian magick, sacrifice in Aztec mythology, the sacred geometry of an astral cathedral, producing ritual theater, personal responsibility in magick, promulgation of the Law of Thelema, textual analysis of The Book of the Law, and more. Other highlights include the original ritual "The Feast of Babalon" and the address given by U.S. National Grand Master Sabazius. They represent some of best modern practical and scholarly work on Ordo Templi Orientis, Thelema, and the magick of Aleister Crowley. The first NOTOCON conference took place in 1997 in Akron, Ohio, and has since been held on alternate years in different cities around the United States. Unity Uttermost Showed! is the second collection of papers from the National Conference to be made available, following the inaugural volume Beauty & Strength for the 2007 EV conference. Ordo Templi Orientis is an international fraternal order of men and women devoted to the pursuit of individual liberty, the study of magick, and the promulgation of the Law of Thelema. Founded in the early twentieth century, it has been shaped by such leading lights as Carl Kellner, Theodor Reuss, Aleister Crowley, Karl Germer and Grady Louis McMurtry.
