For those who want some context: Theosophy has always been a huge part of the New Age movement and the founder of Theosophy, Madame Blavatsky, was a white supremacist. She taught her followers about a "Great White Brotherhood" (aka The Masters) who were racially superior to others. She was also convinced of the existence of superior "root races" (one of them being the Aryans) and various "sub-races"...
Unsurprisingly Theosophy would (for example) merge with the Völkisch movement in Germany (the precursor of the nazi party).
Theosophy with its belief in a secret underground realms, ancient high cultures, lost continents, superior alien races and so on and so forth, was one of the big influences on the late 20th century New Age movement.
