In those days, whoever sang in praise of Sriman Narayanan and about his goodness were called Aazhvaargall. There are 12 Azhvaars in all. They sang the "Divya Prabandham". The first part of Divya Prabandham is " Thiruppallaandu", sung by "Vishnuchithar". He lived nearly 1100 years back. Since he was
