The Sudarsana Chakra is a spinning, disk-like super weapon with 108 serrated edges used by Lord Vishnu. It is usually portrayed on the right rear hand of the four hands of Vishnu, who also holds a conch in his left fore hand, a mace in his left rear hand, and a lotus bud in his right fore hand. According to the old texts, The Sudarsana Chakra is used for the ultimate destruction of an enemy who represents darkness.

The great acarya Vedanta Desika composed this chant called Sudarsana Astakam to ward off a dark plague that afflicted the region at his time. Since then this powerful chant has been used in practice and ritual to ward of negative or evil energy and bring forth positivity.
