Thiru Mangai Azhvaar refers to the Karambanur Lord as the 'Perfect Lord' thus giving him all the glory in just one word
“Peraanai Kurungudi En Perumanai, Thiruthangal Ooraanai
Muthu Ilangu Kaar Aar Thin Kadal Ezhum
Malai Ezh Il Ulagu Ezhl Undu
Aaraathu Enru Irunthaanaik Kandathu Then Arangathey”- 1399
At many a Divya Desam, Thiru Mangai Azhvaar has showered several verses of praise, referring to the location, describing the Lord, referring to his postures, comparing him with Lords he has seen else where and showering heaps of praise.
However, there are temples where he has made a reference only in passing.Thiru Karambanur Divya Desam near Srirangam is one such temple where he makes only a passing mention. But the lack of verses (quantity) is made up by the quality of reference.
Thiru Mangai Azhvaar showers the Karambanur Lord with the ultimate praise referring to him as Uthamar, the perfect Lord. This is the only Divya Desam Lord that Thiru Mangai has referred to as 'Uthamar'. Hence, with just one word, he has positioned the Karambanur Lord as the Ultimate place to visit for us to see the 'Perfect One'.
