Similar to the Swastica. That was originally a Hindu/Budist religeous symbol, bastardised by Hitler.
Hitler was very supersticious and very much into the occult, which is probably why he adopted these symbols into his own purpose.
I also think that the Goths originated from Germany. You should go to Leipzig, old eastern Germany and look at the architechture there, as well as the people. I would safely say that between 40 and 50 percent of the people there are Goths.
