Nazi occult

I have always been fascinated by the Nazi's interest into the occult. They must have known something we did not. No way they would have wasted that much time and money on occult explorations without some sort of yield from these endeavors. Andd it cant just be a coincidence that they were reported to have set up camps in Brazil years before their downfall. I think that they wanted to go underground and give the illusion that they were defeated.
