Campbell writes that Bailey's books are a reworking of major Theosophical themes, with some distinctive emphases, and that they present a comprehensive system of esoteric science and occult philosophy, cognizant of contemporary social and political developments. Steven J. Sutcliffe points out that both Bailey and Blavatsky's work evoke a picture of Tibet as the spiritual home of the Masters and that Bailey claimed a more-or-less direct lineage to Blavatsky. He describes Bailey as a 'post-Theosophical' theorist, reporting that Bailey received instruction from "former personal pupils of Blavatsky" and notes that her third book ("A Treatise on Cosmic Fire") not only reproduces Blavatsky's apocryphal Stanzas of Dzyan but is dedicated to Blavatsky, as well.
