CC Madhya 6.177
saba khaṇḍi’ prabhu nija-mata se sthāpila
The Bhaṭṭācārya presented various types of false arguments with pseudo logic and tried to defeat his opponent in many ways. However, Śrī Caitanya Mahāprabhu refuted all these arguments and established His own conviction.
The word vitaṇḍā indicates that a debater, not touching the main point or establishing his own point, simply tries to refute the other person’s argument. When one does not touch the direct meaning but tries to divert attention by misinterpretation, he engages in chala. The word nigraha also means always trying to refute the arguments of the other party.
