When Tavayogi and I were traveling to Bukit Rotan, I played Ramalinga Adigal's song on my car player. He listened intently, his hands clapping to the rhythm. After some time he mentioned that listening to Ramalinga Adigal's songs itself will bring one to the state of Jnana. Indeed that is true.
Listen to these wonderful devotional songs by Adigalar and other saints.
