Where did you learn all this stuff?
It's Blavatsky again.
The Secret Doctrine by H. P. Blavatsky
Inspired but misleading move to modernize mysticism by associating doctrines derived third-hand from the Vrajnayana
dhyana texts which describe hypnagogic experiences during various kinds of trance, familiar to us mostly from their summary in
Liberation Through Hearing (aka the Tibetan Book of the Dead), with the anachronistic scientific theories of the 19th century, which attempted to describe changes in elevation and water-level in terms of rising and submerging continents like Atlantis and Lemuria (since replaced with ideas of supercontinents like Pangaea and Gondwanaland.) Inspired a lot of the "weird fiction" of the past two centuries, such as Robert E Howard, Edward Bulwer-Lytton, H P Lovecraft, and J R R Tolkien. Easily debunked by anyone who spends half a
bhang worth of time with an actual lama.
