This expanded edition features a new analysis by esoteric teacher and author, J. Daniel Gunther, who provides Qabalistic insights into the poem s extraordinary depth. James Wasserman, a well-known writer and student of Crowley, has expanded upon the myth of Marsyas and Olympas, while placing AHA! within the context of Crowley s overall life and teaching. Frater Achad, one of Crowley s most important early disciples, wrote an excellent but little-known commentary on AHA! that is included here. This volume also features an essay by Dr. Israel Regardie, a primary Crowley biographer and spokesman.
