Why did Hitler decide to copyright the India's spiritual symbols and concepts?

Just wondering since the whole concept of "Aryans" and the "swastika" had originated from India.........I am just wondering why didn't Hitler call his race the "Nordic race" or the "Visigoth race" and why didn't he use some sort of symbol traditionally represented Germany acurately? like a sword with a Cross through it to represent the First Reich. It makes no sense that Hitler would decide to borrow spiritual concepts from a race of "inferior dark skinned people" for his race of "superior white skinned people"........
