Complete and unabridged, here is the unparalleled landmark of occult philosophy and lost history that reshaped the modern spiritual mindset and continues to fascinate readers today.

There is perhaps no greater enigma in modern Western literature than The Secret Doctrine. The controversial Russian noblewoman Madame Helena Petrovna Blavatsky told the world that the book restored humanity's lost history and destiny. Its insights, she said, had been gleaned from long-secret books of wisdom and her tutelage under mahatmas, or great souls: adepts from the East who exposed the seeker to their esoteric teaching.

To read The Secret Doctrine is to enter a mysterious world of ancient cosmology and spiritual-scientific insights, which tell of humanity's unthinkably ancient past and its burgeoning evolution into a new, more refined existence.

For the first time, Blavatsky's encyclopedia arcana is available in a reset and redesigned single-volume edition, complete and unabridged. Its truths and challenges are available to the intrepid reader, who may find yet-unknown insights within its pages.
