It is also hallowed by the hymns (pasurams) of Tirumangai Azhvar, the ancient preceptor and a staunch follower of Vaishnavism. This place is also venerated as an avatara-Sthala because it is the birthplace of the illustrious Srivaishnava scholar, philosopher and preceptor, Vedanta Desika (1268-1369 A.D.).

During the famous Brahmotsavam celebrations of Varadarajasvami in the month of Vaikasi (May-June), Varadaraja Perumal visits the shrine of Vedanta Desika in Thoopul and stays there for three days. On the third day of the Brahmotsavam is held the well-known Garuda Seva procession, and on this occasion, Varadarajasvami comes to Thoopul and presents his garland (mala) to his devotee, Desika. A chunk of devotee joined the sacred procession. Mohini Avatara is considered as one of the sacred festival. Again on the occasion of this celebration, which falls on the fifth day of the Brahmotsavam, Lord Varadaraja goes into the Thoopul sannidhi and gives His garland to Desika. This is repeated on the Punyakoti-vimana procession, which is on the ninth day of the Brahmotsavam.
Lord also pays a periodic visit on the occasion of Chitra Pournami day; on this occasion lord Varadaraja Perumal comes to visit Desika at Thoopul. Again, on the twelfth day after Vaikunta Ekadasi, Perumal with the deities of Sri Devi and Bhu Devi (Ubhaya-nachiyar) on the occasion of Anushtanakulam festival, go to the tiny village of Sevelimedu, about three kilometers from Periya Kanchi, where there is a shrine for the Srivaishnava Acharya, Ramanuja and also the ancient well from which this great preceptor brought water for the tirumanjanam (abhishekam) of Varadaraja Perumal everyday. On the way back from Sevelimedu to their temple they halt for a while at the shrine for Desika. Thus, the frequent mutual visits of Lord Varadaraja and Sri Vedanta Desika reflect the close affinity between them. The periodic visit of the Lord also reflects the sanctity of the temple.
