In her thirties, Craddock left her Quaker upbringing. She developed an academic interest in the occult through her association with the Theosophical Society beginning around 1887. Through her writing, she tried to synthesize translated mystic literature and traditions from many cultures into a scholarly, distilled whole. As a freethinker, she was elected Secretary of the Philadelphia chapter of the American Secular Union in 1889. Although a member of the Unitarian faith, Craddock became a student of religious eroticism, then proclaimed she was a Priestess and Pastor of the Church of Yoga. Never married in a traditional sense, Craddock claimed to have a blissful ongoing marital relationship with an angel named Soph. Craddock stated her intercourse with Soph was so noisy, they drew complaints from her neighbors. Her mother responded by threatening to burn Craddock's papers, and unsuccessfully tried to have her institutionalized.
