The existence of Madame Blavatsky's occult 'Masters' has been fiercely debated for more than a century. Although scores of books have been written about her, none has focused on the historical identities of these elusive teachers. This book profiles 32 of Blavatsky's hidden sponsors, including leaders of secret societies in Europe and America, religio-political reformers in Egypt and India, and even British government agents. The milieu in which she carried out her spiritual quest is vividly revealed as a hotbed of revolutionary plots and secret coalitions. But beyond all the politics was a genuine spiritual awakening of global significance.
