The swastika (Skt. svastika; Tib. གཡུང་དྲུང་, yungdrung, Wyl. g.yung drung) is one of the most ancient and universal symbols and is found in almost every known culture of the world. In ancient China, for example, the swastika was a Taoist symbol of eternity, and in India it is considered to be originally a solar symbol, derived from the motion of the sun through the four quarters and seasons.
