Swami Vedanta Desika has written many stotras and prabandhas. One among the best stotras is Sudarshana Ashtakam, which is entirely written in Sambodhana (direct address) format. This stotra was written to save people affected by a mysterious virus and ensure good health. Among the Pancha Ayudhas of Lord Narayana, Sudarshana Chakra is more lethal. So, reciting this stotra will remove obstacles and destroy enemies.
In our podcast, we present the upanyasam on Sudarshana Ashtakam by U. Ve. Sriman Dr. D. Srinivasan who explains the significance of the stotra and the benefits bestowed by its recital. Let us listen and benefit from it.
