The main Vaṭakalai theologian, and probably the most important Śrī Vaiṣṇava teacher after Rāmānuja. Beyond hagiography little is known of his life. He is said to have been born at Tūppiḷ, near Kāñcīpuram, and to have spent his life in the major centres of Tamil Śrī Vaiṣṇavism, such as Śrīraṅgam. Vedāntadeśika is close to Rāmānuja in his theology, and wrote a number of subcommentaries on the latter's works. Prolific both as a poet and theologian, he composed a wide variety of works in Sanskrit, Tamil, and maṇipravāḷa. These include his defence of Vaiṣṇavism in works such as the Rahasyatrayasāra, Paramatabhaṅga (Paramatapaṅkam), and Nyāyasiddhāñjana. Also notable is the Varadarājapañcāśat, a popular eulogy addressed to Viṣṇu as Varadarāja, which condenses the principles of Vedāntadeśika's teaching into 50 verses. See also prapatti; Vaṭakalai.
