Originally published by The Supreme Grand Lodge of the Ancient Mystical Order Rosae Crucis (AMORC) in 1918 and again in 1929, with several reissues, the Rosicrucian Manual is an official manual for new members of the AMORC and Rosicrucianism. The AMORC Imperator and author of the book, H. Spencer Lewis, describes the manual as a "Guide to the Work and Studies of the Order." It contains a greeting and preliminary instructions, as well as a description of the AMORC and its important officers, general and special instructions to Members and Lodges, Mystic Symbols and their meanings, magical and alchemical explanations, and a dictionary and FAQ.HARVEY SPENCER LEWIS (1883-1939), a well-known Rosicrucian author, mystic, occultist, alchemist, and inventor, was the founder of the Ancient Mystical Order Rosae Crucis (AMORC) in the USA, as well as its first Imperator from 1915 until his death. Born in Frenchtown, New Jersey, Lewis used his training as a commercial artist for an advertising company to promote the AMORC in its early days through print ads and pamphlets. Lewis believed it was his mission to spread modern mysticism throughout the United States, which he did by promoting AMORC tours, appearing on radio shows, giving demonstrations, writing books, and inventing mystical devices. His inventions include the Luxatone, the Cosmic Ray Coincidence Counter, and the Sympathetic Vibration Harp.
