"Rex de arte Regia" (The Magical Diary of Baphomet). — Between 1914 and 1918 Crowley's own diary Rex de Arte Regia, records a long series of 309 acts of sexual magic for a variety of purposes. These included both spiritual aims, such as offering praise to Pan or attaining supernatural powers, and more material aims, such as fascinating mistresses or enhancing his youth and sexual attraction.

Of these, the largest number (48) were employed to for the purpose of generating money. Increasingly worried about his own finances, Crowley developed a sexo-economic technique of imagining a shower of gold coins raining down at the moment of climax. At least in his opinion, this worked, since he claimed to receive several unexpected checks and offers showing up out of the blue. (...)

— [This diary was kept in parallel with the present diary; indications of “Op.,” “Opus” or “Operation” followed by a number are usually crossreferences to Crowley’s O.T.O. diary. (Op. refer to 'operations' from the "Rex de arte Regia".)]
