Here are all of the references to Theosophy by Alice A. Bailey (AAB) in her voluminous writings and those given to her by Djwhal Khul (DK). Links on these pages of the Laws of Alice A. Baileyare to the online books at the Lucis Trust website.
AAB was an early convert to Theosophy but then founded her own Arcane School. AAB claimed that “All the Theosophy that I knew had been taught me by personal friends and pupils of H.P.B.” – see full quote below. “S. D.” in these quotes of course stands for The Secret Doctrine by Helena P. Blavatsky (HPB).
You might find Post-Enlightenment Mystics: Madame Blavatsky an interesting take on HPB. Also check out DID H. P. BLAVATSKY RETURN AS JOHN F. KENNEDY?’ by author Joseph J. Dewey where he comes to an amazing conclusion based on handwriting analysis.
Below are the quotes I found:
Subba Rao says in Five Years of Theosophy, page 102: “As a general rule, whenever seven entities are mentioned in the ancient occult science of India in any connection whatsoever, you must suppose that those seven entities came into existence from three primary entities; and that these three entities, again, are evolved out of a single entity or monad. To take a familiar example, the seven coloured rays in the solar ray are evolved out of three primary coloured rays; and the three primary colours coexist with the four secondary colours in the solar ray. Similarly the three primary entities which brought man into existence coexist in him with the four secondary entities which arose from different combinations of the three primary entities.” Read also S. D., I, 190, 191.
