A Vaisnava sannyasi never accepts an invitation from a party who considers Mayavadi sannyasis and Vaisnava sannyasis to be one and the same. In other words, Vaisnava sannyasis do not at all like to associate with Mayavadi sannyasis, to say nothing of eating together. This principle must be followed by the sannyasis of the Krsna consciousness movement. That is the instruction of Sri Caitanya Mahaprabhu given by His personal behavior.
