As evidence that Chicago's stake in the occult is not just historical, I'd like to post a screenshot of the Occult Chicago calendar on Sunday June 24th.
Alchemy Arts is hosting two events, including a lecture regarding the distinction between the Left vs. Right hand path by Dr. George J. Seig.
Aum Ha Lodge is hosting their free monthly Tarot for Fun and Prophecy class, as well as their monthly public performance of the Gnostic Mass.
