At its original publication, this instruction was assigned neither a Document Class nor a catalogue number. In fact, it has never been published with official A∴A∴ sanction, outside of individual contemporary lineages. The formulation of the A∴A∴ was, in 1907, in its early stages, and these details may not have as yet been formalized. Later (in the "Syllabus" in Equinox I:10), it was designated as a Class C Document, and given the number XLI. No explanation was given for the assignment of this number.
