Isis Unveiled: Two Volumes in a Slipcase (Revised)

HPB's first major work, originally published in 1877. The most astounding compendium of occult facts and theories in Theosophical literature. It proclaims the existence of mystery schools under the guardianship of men who are servants for truth. It outlines a movement by the Guardians of the Ancient Wisdom to preserve and protect the ageless truths, until in later times they would again become known for the spiritual benefit of all.
