Vyakhyana Saram:
In pasuram four, Azhvar called those who seek kaivalya to come join him in performing mangalashasanam. In this pasuram, they speak of their (now changed) nature and come, and he joins with them.

When he called them, Azhvar told them to come after leaving their limitations (of experiencing their own soul) ("varambu ozhi vandhu ollai kUduminO"), to seek only Him ("namO nArAyaNAya") such that true devotees accept them and others disregard them. In that, (for those who sought kaivalya before) giving up the wrong goals and becoming those that seek only Him are their own acts. What do they need to do so that who are disposed to Him accept them and those who are adverse to Him abandon them? For that, they wear the Srivaishnava marks of Sudarshana Chakra (and Panchajanya) on their shoulders and speak of that as they come to join Azhvar.
