Vyakhyana Saram:
Madhurakavi Azhvar states that Nammazhvar made him sing his praises for all time ("vIvilkAlamisaimAlaigaLEththi mEvap peRREn"). In the pasurams before, he had said that Nammazhvar saved him; but, since he was deeply involved in all kinds of lowly activities since time immemorial, why would he not go back to them again? He replies that the extent of Nammazhvar's grace is such that that would never happen to him.

inRu thottum:
The term today refers to the day that, even ahead of being attached to Him, Madhurakavi Azhvar became attached to Nammazhvar. Namamzhvar's grace is such that it does not bear fruit on some other day; it has begun on the this day itself.

ezhumaiyum empirAn:
Without any difference in time or era, Nammazhvar has helped him for all time to come. ezhumaiyum refers to all time to come.

empirAn:
Nammazhvar referred to Him as pirAn ("pirAn perunnilangkINdavan"), while Madhurakavi Azhvar refers to Nammazhvar as pirAn.

ninRu:
Since Nammazhvar stands at the end of the goal seeked, it is a stable goal. Therefore, Madhurakavi Azhvar says ninRu - steadfast. Just as humans became an unwanted matter to Nammazhvar ("mAnidam pAda vantha kaviyEnallEn"), He has become unwanted to Madhurakavi Azhvar. Nammazhvar's grace is such that there is no need to become attached to him in order to get bhagavat anubhavam; attachement to Nammazhvar includes bhagavat anubhavam.

kunRamAdath thirukkurugUr nambi:
Just as the completeness of Nammazhvar cannot be measured so too the height of the mansions in Thirukkurukoor cannot be measured. Nammazhvar's greatness adds greatness to the city itself. Nammazhvar referred to Thirukkurukoor as the city with mountainous mansions ("kunRampOl maNimAdaneedu thirukkurukoor") and as it is set in his heart Madhurakavi Azhvar echoes the same.

nambi:
Nammazhvar's completeness is such that not only can he save himself but he can also save Madhurakavi Azhvar. His completeness is not such that one has to praise him and then another person; praising Nammazhvar alone is sufficient.

enRum ennai igazhvilan:
Madhurakavi Azhvar is giving the reason for praising Nammazhvar. Nammazhvar has given him grace such that Madhurakavi Azhvar will never think of anything else. Would Nammazhvar who saved him without considering his lowly nature allow him to be led astray by anything else?

kANminE:
Madhurakavi Azhvar is asking everyone to see that unlike others who sing only His praises, he has become one who would sing none but Nammazhvar's praises.
