True meaning of swastika

Before Hitler started using it, swastika was a popular symbol of luck in a lot of cultures. It was used in South Asia, in Buddhism, Jainism and Hinduism. It was also used in many east asian cultures, but also in Europe. In the Sami tribes of Scandinavia, by germanic tribes and even by celts. It was also widely used by Greeks and Romans. This symbol somehow was found in almost exact shape in the native american tribes. But now after World War 2 everybody seems to remember only about the Hitler's usage.
