The Sudarshana Chakra is a spinning, disk-like weapon with 108 serrated edges used by the Hindu god Vishnu. The Sudarshana Chakra is generally portrayed on the right rear hand of the four hands of Vishnu, who also holds a shankha (conch shell), a Gada (mace) and a padma (lotus).
The Sudarshana Chakra may be depicted as an ayudhapurusha (anthropomorphic form). He is depicted as a fierce form of Vishnu. While the Sudarshana Chakra is depicted as a subordinate figure with Vishnu, in many South Indian Vishnu temples, the Chakra as an ayudhapurusha is worshipped in its own shrine attached to the central temple.
According to the Puranas, Sudarshana Chakra is used for the ultimate destruction of an enemy. The depiction of Vishnu with Sudarshana Chakra also means that Vishnu is the keeper-owner of the celestial bodies and heavens.
