Everything becomes more clear when Adam Gorightly takes a moment to explain.
The current section of Illuminatus! that the online reading group is in, the Tenth Trip, starts out with a quotation from the works on one Omar Khayyam Ravenhurst, K.S.C. (i.e, Kerry Thorney) on page 657:
Ye have locked yerselves up in cages of fear; and, behold, do ye now complain that ye like freedom.
The quote is attributed to the "Epistle to the Paranoids," which is in turn is attributed to a larger work, "The Honest Book of Truth," but as Adam Gorightly explains in his new blog posting at Historia Discordia, "Illuminatus! Group Reading Week 62: The Epistle to the Paranoids," those are in fact two separate documents.
Adam then reproduces the three part "Epistle to the Paranoids," and it makes amusing reading. You will learn, for example, about the esoteric significance of the sacred numbers 0-9, "which "appear with surprising frequency in Illuminati-controlled radio broadcasts."
