A thousand years ago Christian battled Muslim for possession of a strip of land upon which both their religions were founded. These Crusades changed the course of Western history, but less known is the fact that they also were the meeting ground for two legendary secret societies: The Knights Templar and their Muslim counterparts, the Assassins. In The Templars and the Assassins: The Militia of Heaven, occult scholar and secret society member James Wasserman provides compelling evidence that the interaction of the Knights Templar and the Assassins in the Holy Land transformed the Templars from the Pope's private army into a true occult society, from which they would sow the seeds of the Renaissance and the Western Mystery Tradition. Both orders were destroyed as heretical some seven hundred years ago, but Templar survivors are believed to have carried the secret teachings of the East into an occult underground, from which sprang both Rosicrucianism and Masonry. Assassin survivors, known as Nizari Ismailis, flourish to this day under the spiritual leadership of the Aga Khan. Wasserman strips the myths from both groups and penetrates to the heart of their enlightened beliefs and rigorous practices, delivering the most probing picture yet of these holy warriors.
