This is a practical instructional essay from the chaos magic tradition, drawn from the *Internet Book of Shadows* (1999), written by a self-described professional magician explaining how to adapt Austin Osman Spare's sigil magic for use with paying clients. The central problem it addresses is ethical and practical: since clients typically lack knowledge of sigil magic, the author cannot simply charge a sigil on their behalf (which would embed the client's desire in the author's own subconscious), so they devise a method to have clients unknowingly perform the charge themselves. The process involves distilling a client's wishes into a precise "will sentence," constructing a sigil from it, then sending the client instructions framed as a simple ritual — timed so the client has forgotten the original wording and cannot consciously recognize what the sigil encodes. A notably distinctive feature is the use of a surgical lancet to draw a drop of the client's blood onto the sigil during consultation, which the author recommends especially for protective or offensive ("antipersonnel mine") workings. The text closes with a case-log of client outcomes, presented as empirical evidence of the method's effectiveness across goals ranging from business success to harming named enemies. Its perspective is that of a practitioner treating magic as a professional service discipline, focused on procedural reliability and client management rather than spiritual or philosophical elaboration.
