Lord Sudarshana is the chief deity invoked in the Homa.

Sudarshana Chakra is the discussion held by Maha Vishnu, the Protector. It protects His devotees and all who surrender to It, against all evil. It will uphold Dharma, and annihilate anybody who is the doer of Adharma. Sudarshana Homa spreads positive energy and revitalizes the environment and the soul of those present where the Homa is performed. This Homa is also performed for good health as the Chakra has healing qualities.
