Do not mix with serpent Mayavadis

Srila Bhaktisiddhanta Sarasvati Thakura warns all devotees engaged in
broadcasting the Krsna consciousness movement not to speak to the
impersonalist Mayavadis who are always determined to oppose such theistic
movements. The world is full of Mayavadis and atheists, and the political
parties of the world take advantage of Mayavada and other atheistic
philosophies to promote materialism. Sometimes they even back a strong party
to oppose the Krsna consciousness movement. The Mayavadis and other atheists
do not want the Krsna consciousness movement to develop because it educates
people in God consciousness. Such is the policy of the atheists. There is no
benefit in feeding a snake milk and bananas because the snake will never be
satisfied. On the contrary, by taking milk and bananas the snake simply
becomes more poisonous (kevalam visa-vardhanam). If a snake is given milk to
drink, its poison simply increases. For a similar reason, we should not
disclose our minds to the serpent Mayavadis and karmis. Such disclosures
will never help. It is best to avoid association with them completely and
never ask them about anything confidential because they cannot give good
advice. Nor should we extend invitations to Mayavadis and atheists nor
accept their invitations, for by such intimate intermingling we may become
affected by their atheistic mentality (sangat sanjayate kamah).
