The holy discus is known as Sudarshana, Chakra, Hethiraja or Rathanga in Sanskrit. It is known as Aazhi in Tamil. This stotra contains eight Slokas in the praise of Sudarshana. This stotra is in the Vrutham (meter) of "Thagana Nagana Bhaganaathmakam". This stotra was written by Swami Vedanta Desika before starting his great book "Paramatha Bhangam", as a prayer. Reciting and listening to this stotra give wealth, protection and good health. PS: The cover photo shows the deity of Sudarshana Chakra
