Caitanya Mahāprabhu also had a discussion with the Tattvavādī community, and the Tattvavādīs felt themselves to be inferior Vaiṣṇavas.
The Tattvavādī sect belongs to Madhvācārya’s Vaiṣṇava community, but its behavior differs from the strict Madhvācārya Vaiṣṇava principles. There is one monastery named Uttararāḍhī, and one of its commanders was named Raghuvarya Tīrtha Madhvācārya.
