The “collective biography” genre includes most of my writing, and like its predecessor this one features 32 main characters in turn of the (20th) century esoteric circles. The distinction between “Adepts and Mahatmas” and “Initiates” in the two books is generational, not an attempt to define them as inherently at different spiritual levels. The latter are generally younger and were disciples or associates of the former. Due to the voluminous discussion of some of these Initiates by Dominic Green in The Religious Revolution, I have posted the introduction to Initiates of Theosophical Masters on academia.edu.
