The Sudarshan Chakra signifies the infallible weapon of Lord Narayana, the discus. With the discus, Lord Narayan removes the head, where negative thoughts are born. With the Sudarshan Homa, we invoke Lord Narayana to bless us with Sudarshan, which means good vision (‘Su’ means good, and ‘Darshan’ means vision). Our experience of the world can be changed by changing our perception. The Sudarshan Homa helps in removing mental blocks, removing ignorance and making one’s perception positive.
