Vyakhyana Saram:
Madhurakavi Azhvar explains how he got such a great gain through the help he got from Nammazhvar. Why would Nammazhvar give him such a help? He says that he was low, so low that all good things abandoned him, and therefore he became attached to Nammazhvar and Nammazhvar helped him.

nanmaiyAl mikka nAnmaRaiyALargaL:
Those great and pure people who live by the four Vedas, who are home to divine qualities, who recite, follow and have no other wealth other than the Vedas.

punmaiyAgak karudhuvar:
Such Vedic people will not just consider him as one who has low qualities, but actually think of him as low qualities personified. He says that his stature is so low that all great people except Nammazhvar would tend to abandon him.

nAnmaRaiyALargaL punmaiyAgak karudhuvar:
The brahmins who recite nothing but the Vedas and who are submerged in the smell of the Vedas will not consider that he has low qualities but that all low qualities have gained a physical form as him.

annaiyAy aththanAy ennai ANdidum:
To such a person as him, Nammazhvar became all relations such that he has no relatives except Nammazhvar. Other than Nammazhvar, he has no other refuge. That which a mother, a father and a lord would do was all done for him by Nammazhvar. That was the relationship between Sriman Narayana and Nammazhvar and now he has attained that same relationship with Nammazhvar.

thanmaiyAn:
Nammazhvar has this lofty characteristic naturally.

nambiyE:
Nammazhvar is a pUrna (nambi) because not only did he drive away his own errors but he also removed Madhurakavi Ahzvar's errors. Nammazhvar just did not do something that another person might have done; he has done that which everyone else does together; therefore, he is complete. Madhurakavi Azhvar says that Nammazhvar's completeness is such that it lifts even those who are nothing but a personification of low qualities.
