This is in Thirunangur itself. The Moolavar is Sri Vaikunta Nathan in a sitting posture facing east and the Thaayar is Sri Vaikunta Valli. This Lord has come from Vaikuntam itself and hence there is no legend, except that the temple tank contains the water of Vraja Nadhi, which flows in Vaikunta. Thiru Mangaiazhwar has sung in praise of this Lord.
