Today we will look at the meaning of the Divya Nama सर्वगः and also something about the approach of the Tamil Saints, Azhvars to Vaishnavism.
Sarvagah from-
सर्वगः सर्ववित् भानुः विष्वक्सेनो जनार्दनः।
वेदो वेदविदव्यङ्गो वेदाङ्गो वेदवित् कविः॥

Sarvagah means he is everywhere.
He goes everywhere.
Bhagavan sees everything.
Bhagavan notices everything.
That's how he manages the world.
This management is what is called palana
Maintenance of the state of the universe as it is, that's what is called stithi.
That's Bhagavan's responsibility.
He will not allow the world to turn into chaos.
He ensures that there is a system in place for everything.

How does Bhagavan do this?
Because he is the root cause of the world.
World has come out of him.
World is made up of him.
So, definitely he is there in everything.

He goes to everyone who calls him.
Bhagavan reaches out to everyone who calls him.
It is not possible that you called him and he didn' respond.
Because Bhagavan is Sarvagah.
The Azhvars are Tamil Vaishnavite Saints.
There were twelve of them.
Collectively they have authored 4,000 verses called the Nalayiram Divya Prabandham.
Bhagavan is there in the Vedas, Puranas, Itihasas.
Which are the aspects of Bhagavan that the Azhvarars picked up, focused on and spread; this is what we will try to see briefly.
Out of the names Vishnu, Vasudeva, and Narayana each representing certain aspects of Bhagavan, the Azhvars focused on Narayana.
Azhvars also said that Bhagavan is one among the Trimurthis, but independent of the other two and his tasks much more than the other two.
Azhvars only gave prominence to Bhumi Devi as Bhagavan's wife.
Azhwars have given importance to Bhagavan's saguna aspect, his physical form, even his weapons
This conveys a feeling that Bhagavan is available to us, Bhagavan is accessible, Bhagavan is approachable.
He is the Lord of abundance.
Wherever Bhagavan is there you will see abundance.
Bhagavan rules over the material world and also a world which only his Bhaktas reach.
The concept that the material world was Bhagavan's body itself was highlighted by the Azhvars.
Azhvars started the tradition of addressing Bhagavan with the 12 names starting with Keshava.
They said Bhagavan can be known through the Vedas, but even the Vedas can not reveal him completely.
Bhagavan' kindness and his affection for his devotees is highlighted.
Out of the five forms of Bhagavan, the Azhvars were more drawn towards the Vibhava and Archa forms because they are the most beneficial for his devotees.
Their emotion towards Bhagavan was love.
Not love at the level of an equal.
Their expression of love was worshiping his lotus feet.
About Bhagavan, they were always astonished, amused and in reverence.
