Bektashi Order
One of the books that Glauer inherited from Termudi featured a note from Hussein Pasha, which piqued his interest in the Sufi Bektashi Order, in regards to their alchemical and numerological practices. Speculations say he might have converted to Islam with Sufi-orientation, although the evidence (from his own semi-autobiographical writings) is rather tenuous on this point. In his autobiographical novel "Der Talisman des Rosenkreuzers" ("The Rosicrucian Talisman"), Sebottendorff distinguishes between Sufi-influenced Turkish Masonry and conventional Masonry.
