Returning to New York City in September 1855, after "a long tour in Europe and Africa", he gave a public lecture to African Americans on the subject of emigrating to India. Randolph believed that "the Negro is destined to extinction" in the United States. After leaving the sea, Randolph embarked upon a public career as a lecturer and writer. By his mid-twenties, he regularly appeared on stage as a
trance medium and advertised his services as a spiritual practitioner in magazines associated with
Spiritualism. Like many Spiritualists of his era, he lectured in favor of the
abolition of
slavery; after emancipation, he taught literacy to freed slaves in New Orleans. In addition to his work as a
trance medium, Randolph trained as a doctor of medicine and wrote and published both fictional and instructive books based on his theories of health, sexuality, Spiritualism and
occultism. He wrote more than fifty works on magic and medicine, established an independent publishing company, and was an avid promoter of
birth control during a time when it was largely against the law to mention this topic. Randolph was also a significant importer of
hashish, which he considered to have both medical and spiritual properties. Having long used the pseudonym "The Rosicrucian" for his Spiritualist and occult writings, Randolph eventually founded the
Fraternitas Rosae Crucis in 1858, and their first lodge in
San Francisco in 1861, the oldest
Rosicrucian organization in the United States. This group, still in existence, today avoids mention of Randolph's interest in
sex magic, but his magico-sexual theories and techniques formed the basis of much of the teachings of another occult fraternity, the
Hermetic Brotherhood of Luxor, although it is not clear that Randolph himself was ever personally associated with the Brotherhood. == Belief and teaching ==
