The swastika is an equilateral cross with arms bent at right angles, all in the same direction, usually the right, or clockwise. The swastika is a symbol of prosperity and good fortune and is widely dispersed in both the ancient and modern world. It originally represented the revolving sun, fire, or life. The word swastika is derived from the Sanskrit swastika which means, "conducive to well- being". The swastika was widely utilized in ancient Mesopotamian coinage as well as appearing in early Christian and Byzantium art, where it was known as the gammadion cross. The swastika also appeared in South and Central America, widely used in Mayan art during that time period.
In North America, the swastika was a symbol used by the Navajos. The swastika still continues today to be an extensively used sign in Buddhism, Jainism, and Hinduism. In Buddhism, a swastika represents resignation. In Jainism, it delineates their seventh saint, and the four arms are also used to remind the worshiper of the four possible places of rebirth; the animal or plant world, in Hell, on Earth, or in the spirit world. To Hindus, the swastika with the arms bent to the left is called the sathio or sauvastika, which symbolizes night, magic, purity, and the destructive goddess Kali. In both Hinduism and Jainism, the swastika or sathio is used to mark the opening pages or their account books, thresholds, doors, and offerings.
