Definition of Mayavadi

So avaisnava-mukhodgirna puta-hari-kathamrtam, sravanam na kartavyam. And it
is forbidden, “Don’t hear. ” Why? “Hari-kathamrta, krsna-katha, the message
of God, the words of God, Bhagavad-gita? He may be anything, but the katha
is the same; so what is the harm to hear from an avaisnava?”
Sanatana Gosvami gives the example: sarpocchistha-payo yatha.
Sarpocchista-payo yatha. Sarpocchistha. . . Just like milk, everyone knows,
a very nice food, most nutritious food, but if it is touched by the life of
a serpent, immediately spoiled. Immediately. Another place, Caitanya
Mahaprabhu says, mayavadi-bhasya sunile haya sarva nasa. If we hear
Mayavadi-bhasya, commentaries by the Mayavadis, those who do not accept the
Personality of Godhead. . . They are called Mayavadis. Mayavadi means they
see everything maya. Even Krsna is maya. That is called Mayavadi.
