Highlights from Nampil̤l̤ai's Vyākhyānam as documented by Vadakkuth Thiruvīdhip Pil̤l̤ai:
Nalguravum Selvum - Poverty and its opposite, wealth. Both are perceived by Āzhvār as being owned by Emperumān, who is the sovereign lord of all. The term "Āy" (being) is appended to each word, indicating an essential and inherent attribute of Emperumān.
