Vyakhyana Saram:
Jagadacharya Ramanuja created the 74 simhasanadhipathis to spread the glorious Srivaishnava sampradhayam. One of these was Mudumbai Nambigal. In his lineage was born the incomparable Sri Krishnar. He lived in the Uththara veedhi of Srirangam and hence was called Vadakkuth Thiruveedhip Pillai.

He was the disciple of Nampillai. During the day he would hear Nampillai's kalakshepam on Bhagavad Vishayam - the commentary on Azhvar's Thiruvaymozhi, and in the night he would write them down to the word. This became the grand 36000padi Idu vyakhyanam - the magnum opus commentary for Thiruvaymozhi.

Here Swami Desikan is saluting this great acharya for providing us the Sri Suktis of Swami Nampillai in written form so they continue to last for a long time.
