CC Ādi 7.43
উপেক্ষা করিয়া কারো না কৈল সম্ভাষণে ॥ ৪৩ ॥
upekṣā kariyā kāro nā kaila sambhāṣaṇe
Hearing all this blasphemy, Lord Caitanya Mahāprabhu merely smiled to Himself, rejected all these accusations and did not talk with the Māyāvādīs.
As Kṛṣṇa conscious devotees, we do not like to converse with Māyāvādī philosophers simply to waste valuable time, but whenever there is an opportunity we impress our philosophy upon them with great vigor and success.
