The swastika (Sanskrit: स्वस्तिक) is an equilateral cross with its arms bent at right angles, in either right-facing (卐) form or its mirrored left-facing (卍) form. Earliest archaeological evidence of swastika-shaped ornaments dates back to the Indus Valley Civilization of Ancient India as well as Classical Antiquity. Swastikas have also been used in other various ancient civilizations around the world. It remains widely used in Indian religions, specifically in Hinduism, Buddhism and Jainism, primarily as a tantric symbol to evoke 'shakti' or the sacred symbol of auspiciousness. The swastika is also a Chinese character used in East Asia representing eternity and Buddhism.
