It is true that the swastika has been layered with negative and violent meaning. Sadly, this is from a very short time in the life of this symbol. 16,000 years ago the gammadion and swastika were symbols of oceanic and atmospheric gyres, and a symbol for the movement of time. It became an important symbol in Eastern cultures, used to communicate the concepts of health, power, and wisdom. But one must know what a word or symbol means to the culture in which it is being used, and use them with care. Perhaps centuries from now this misunderstood symbol will regain some of its previous respectability.
