Vyakhyana Saram:
In this shloka, Swami Desikan is saluting the great Acharya who was first called Lokacharya by Kandhadai Thozhappar after seeing his great magnanimity. His acharya Nanjeeyar called him Nampillai after seeing his great knowledge. He was born on Karththigai thirunakshathram in the month of Karththigai - the same as Thirumangai Azhvar, who is called Kalikanri. Hence he was called Kalikanri Dasar. He is the mahAcharya who gave us the incomparable Idu vyakhyanam for Azhvar's Thiruvaymozhi. His disciple was Vadakkuth Thiruveedhip Pillai whose children were Pillai Lokacharyar (named for Nampillai) and Azhagiya Manavala Perumal Nayanar.
