I suggest that you get more acquainted with the works of Peter Levenda. This researcher has explored a not-too-familiar line of enquiry, that is the occult foundations on which Nazism was based or driven from, presented and explained in his book Unholy Alliance: History of Nazi Involvement with the Occult. A lot of people and/or organizations contributed to build what became the nazi occult mysticism, from Madame Blavatsky and Aleister Crowley to the Thule Gesellschaft, the Order of the Golden Dawn, the Order of the Eastern Temple, Tibetan mysticism, Freemasonry, legends of the Holy Grail, Knights Templar, folklore, etc. More recently, Peter Levenda has worked on another trail of enquiry that led him to discover a graveyard in Indonesia, possibly containing the remains of a very important member of the nazi hierarchy, Hitler himself according to him. You can check his website to learn more about that.
