Swamy Nampillai was the fourteenth Acharya in the prestigious Guruparampara lineage of Srivaishnava sampradaya .
One day Swamy Nampillai asked his Acharya Nan Jeeyar the most relevant question of present day. He submitted to his Acharyar humbly and asked Swamin !!
How can one confirm that he has the qualities of a srivaishnava ?
Nanjeeyar was a chosen disciple of Swamy Parasra Bhattar and naturally possessed all the divine knowledge from his Acharyar .
Nanjeeyar replied !
My child If a person undoubtedly believes that Lord Sriman Narayana in his Archa form gracing us in the temples and house does possess all supreme powers as in Srivaikunta Loka, He can count to be one among a Srivaishnava .
Our Azhwars were possessing that divine quality which made them glorify the Lordships in all the vaishnava divyadesams and Abhimana sthalas .
No doubt the Lord in the Divyadesam also replied to their devotion .
Thirumangai Azhwar had innumerable experiences in this kainkaryam
And , it is generally seen a man loves his son very dearly .
If the same person loves a srivaishnva as dear as his son he can consider to be in the list of srivaishnavas and in case he has been abused by a Srivaishnava and does not react , and accepts his pungent words with cheerful obedience as positive development for his durguna he is a Srivaishnava.
Finally , the Acharya summed up the answer in few words
Archaavatara abhimanam , Bhagavatha Prema and Bhagavatha Katinokthi Bhogyatha buddhi are essential characteristics of a srivaishnava .
If at all any one has these three virtues, he can conclude within himself that he is a Srivaishnava.
