CC Antya 2.171

viśvāsa kariyā śuna caitanya-carita
tarka nā kariha, tarke habe viparīta
Word for word: 
viśvāsa kariyā — with faith and confidence; śuna — just hear; caitanya-carita — the pastimes of Śrī Caitanya Mahāprabhu; tarka nā kariha — do not uselessly argue; tarke — by argument; habe viparīta — will get the opposite result.
Translation: 
Please hear the pastimes of Śrī Caitanya Mahāprabhu with faith and confidence. Do not argue, for arguments will produce a contrary result.
