Greatness of Ramunuja

This Thaniyan is created by Sri Brahmatantra Swatantra Jeeyar (first Jeeyar of Parakala mutt and an immediate devotee of Sri Vedantha Desikan).

Thaniyan's artham in short: 

I love Vedanta Desikan (Acharya or preceptor extraordinarily lauded as such because of his incredible commitment and severe adherence to Vedanthic custom), named VenkatanAthan, enriched with favorability and wonders, who was a container of the kindness (Daya) of his AchArya Sri Ramanuja, and who was decorated with the gems of insight (jnanam) and separation (VairAgyam).
