This is a very important Prabhandham derived from a very
famous debate of Swamy Desikan with leaders of other Mathams in front of
Lord DevanAthan on the banks of PeNNai river . Swamy Desikan defeated
all his challengers and firmly established the Supermacy of
VisishtAdhvaitham over 15 other SiddhAnthams . Lord DevanAthan was very
pleased at the accomplishment of His dear devotee and blessed him
profusely .
