INTRODUCTION We take great pleasure in presenting to the attention of students and investigators of the Secret Doctrines this little work based upon the world-old Hermetic Teachings. There has been so little written upon this subject, notwithstanding the countless references to the Teachings in the many works upon occultism, that the many earnest searchers after the Arcane Truths will doubtless welcome the appearance of this present volume. The purpose of this work is not the enunciation of any special philosophy or doctrine, but rather is to give to the students a statement of the Truth that will serve to reconcile the many bits of occult knowledge that they may have acquired, but which are apparently opposed to each other and which often serve to discourage and disgust the beginner in the study. Our intent is not to erect a new Temple of Knowledge, but rather to place in the hands of the student a Master-Key with which he may open the many inner doors in the Temple of Mystery through the main portals he has already entered.
