Theosophy was embraced and practiced by America’s 19th century elites. If I remember correctly, Blavatsky “channeled” ascended Tibetan mystics during her trances for gullible but rich New Yorkers. Her version of transcendental Theosophy made her a rich woman. I believe some remnants of the Theosophical Society still exist.

"The Lucis Trust is a nonprofit service organization incorporated in the United States in 1922 by Alice Bailey and her husband Foster Bailey, to act as a fiduciary trust for the publishing of twenty-four books of esoteric philosophy published under Alice Bailey's name, and to fund and administer activities concerned with the establishment of "right human relations". These include the Arcane School, a school for esoteric training, World Goodwill, Triangles, a lending library, The Beacon magazine, as well as the publishing company."
