Sri Vedanta Desikan (Swami Desika, Swami Vedanta Desika, Thoopul Nigamaantha Desikan) (1268–1369)) was an Indian polymath who wrote philosophical as well as religious and poetical works in several languages, including Sanskrit, Maṇipravāḷa—a Sanskritised form of literary Tamil—and Tamil.
He was an Indian philosopher, Sri Vaishnava guru, and one of the most brilliant stalwarts of Sri Vaishnavism in the post-Ramanuja period.
He was a Hindu devotee, poet, Master of Acharyas ( desikan) and a logician and mathematician.
He was the disciple of Kidambi Appullar, also known as Aathreya Ramanujachariar, who himself was of a master-disciple lineage that began with Ramanuja. Swami Vedanta Desika is considered to be avatar (incarnation) of the divine bell of Venkateswara of Tirumalai by the Vadakalai sect of Sri Vaishnavite.
Vedanta Desika belongs to Vishwamitra/Kaushika gotra.
On the occasion of 750th anniversary of Vedanta Desika, the Indian postal department unveiled a stamp to commemorate the great philosopher’s life and highly valued works. The stamp was unveiled by Sri Venkaiah Naidu, Vice President of India in May 2019.
