There was a third and a fourth volume of Blavatsky’s Secret Doctrine, which never made it into print. The third volume was typed by third parties, so it is independently confirmed that it existed. Where is it now? The third volume dealt with the “lives of the great occultists down the ages.” The fourth volume was allegedly “almost entirely written, but likewise went to oblivion instead of to the printer.” Where are its drafts?
“The whole book professes to be a commentary on the Stanzas of Dzyan, which HPB (Helena Petrovna Blavatsky) alleged to be a fragment of Tibetan sacred writings of two types, one cosmological, the other ethical and devotional. The Secret Doctrine elucidates the former section of the Stanzas, and her later work, the Voice of the Silence, the latter. The Stanzas of Dzyan are of great antiquity, she claimed, drawn from the Mani Koumboum, or sacred script of the Dzungarians, in the north of Tibet. She is not sure of their origin, but says she was permitted to memorize them during her residence in the Forbidden Land. They show a close parallel with the Prajna Paramita Sutras of Hindu sacred lore.
There are of course charges that she invented the Stanzas herself or plagiarized them from some source. Max Müller is reported to have said that in this matter she was either a remarkable forger or that she has made the most valuable gift to archeological research in the Orient. She says herself in the Preface:
“These truths are in no sense put forward as a revelation; nor does the author claim the position of a revealer of mystic lore, now made public for the first time in the world’s history. For what is contained in this work is to be found scattered throughout thousands of volumes embodying the scriptures of the great Asiatic and early European religions, hidden under glyph and symbol, and hitherto left unnoticed because of this veil. What is now attempted is to gather the oldest tenets together and to make of them one harmonious and unbroken whole. The sole advantage which the writer has over her predecessors, is that she need not resort to personal speculation and theories. For this work is a partial statement of she herself has been taught by more advanced students, supplemented in a few details only, by the results of her own study and observation.”
