Importance of Sadari

In Vaishnava temples, after getting the Theertham, we bow down our head to get the Sadari. Sadari is said to be the form of Sri Nammalwar, who is also named as "Sadagopan". As Sri Nammalwar says in his Thiruvaaimozhi, that all our sins will vanish if we strongly attach ourselves to the divine feet, the thiruvadi of Sriman Narayanan. He also explains that this is the universal way of attaining Mukthi.
