"My information (from my own Master) is that the broad general outline and scope of The Secret Doctrine was conveyed verbally to H.P.B. (Helena Petrovna Blavatsky) by the Masters K.H. and Morya, while the bulk, the esoteric lore, was given to her telepathically by D.K.. She herself gave the correspondences between the esoteric science and the exoteric science of her day. It was in fact a group work. (p. 301/2)"
