A Vaiṣṇava sannyāsī never accepts an invitation from a party who considers Māyāvādī sannyāsīs and Vaiṣṇava sannyāsīs to be one and the same. In other words, Vaiṣṇava sannyāsīs do not at all like to associate with Māyāvādī sannyāsīs, to say nothing of eating together. This principle must be followed by the sannyāsīs of the Kṛṣṇa consciousness movement. That is the instruction of Śrī Caitanya Mahāprabhu given by His personal behavior.
