Helena Blavatsky's cosmology, as presented in her last book, is largely based on a mix of Alice Bailey's work and the novel 'The Coming Race' by Edward Bulwer-Lytton. Her focus on race science, a problematic attitude, led to the development of the racial germ present in Bailey's thesis, where the Aryan race was born and developed in the far north after the sinking of the continent of Atlantis, ultimately leading to the current Europeans.
