Ah the swastika, perhaps the most misunderstood icon of all time. The word swastika comes from the Sanskrit words 'su', meaning 'well', and 'asti', meaning 'to be'. The swastika has not always been used as a symbol of Nazism and was in fact borrowed from Eastern cultures. It seems to have first been used by early inhabitants of Eurasia who revered it as a symbol of prosperity and good fortune. It is an important symbol in Eastern religions, notably Hinduism and Buddhism, among others, and was also used in Native American faiths before World War II.
The Germans of the Third Reich were obsessed not only with proving their Aryan heritage, but they also believed they had found a way to reconnect with these ancient peoples at their point of origin — the inner earth. Sun symbols and swastikas dominated Nazi regalia, architecture and propaganda. It's no accident that the sun symbols and swastikas both share their heritage with the concepts of Agharta or the inner earth and the civilizations that populate that realm. The obsession of the Third Reich with the occult was overhsadowed only by their desire to achieve the sacred realms of the mythical land of Agharta and reunite with the 'Aryan' nations of that domain. The information they uncovered regarding these ancient ideas lives on to this day and cause an uncomfortable stir among those that are loathe to admit that they might have just been on to something.
