He is the chief deity of the powerful Sudarshana Homa. He is a manifestation of Lord Vishnu depicted holding the Sudrarshana Chakra on his rear right hand. In the other three, Lord Vishnu holds a Shanka-conch, Gada-mace and Padma-lotus. Vishnu uses his mighty weapon ‘Chakra’ to grant immediate relief to the sufferings of his devotees. It is a weapon to destroy the enemy and among all of Lord Vishnu’s weapons, the sudarshana is a mobile instrument. It implies that Lord Vishnu is the keeper-owner of celestial bodies in the three lokhas. Lord Sudarshana is considered to be the first step in the bhakti path towards God realization. Lord Sudarshana is known as “Chakarthalzhvaar” in Tamil. This brings the meaning ‘Sage of the Wheel.’ Lord Sudarshana is also worshiped as Paramapurusha and Ayudhapurusha.
Legends have it that the daughter of Viswa Karma, the Architect of the God’s, was married to the sun God and she left him because of his immense heat. It is said that, Viswa Karma put Sun God in a cage and churned him to reduce his heat. The heat was reduced and Sudarshana Chakra, Trishoola and Shakthi, respectively the weapons of Lord Vishnu, Shiva and Subrhamnya were born out of the churning. Sudarshana Chakra was elevated to an independent deity in the name of Lord Sudarshana or Chakrathalzhwar.
