The “swastika” 卐 is an ancient symbol of good fortune found in ancient cultures from all over the world. The positive meaning holds true even in cultures thousands of miles separated and thousands of years apart in time.
The swastika symbol actually seems to have shown up around the same time period in these separate cultures at around the same time. Alot of astronomers believe that there was a celestial event, perhaps a supernova that formed a swastika-looking spiral. These kind of celestial events were usually seen as good fortune in ancient cultures- hence the swastika’s meaning of good luck and fortune to this day by many cultures.
