most dangerous, so-called gurus

Prabhupada: So-called gurus, they are so-called gurus. They are not gurus.

not guru. If you accept so-called guru, that is your misfortune. What can be
done?
Pusta Krsna: Some of them will say some things that Krsna says, but they’ll
take from other places also. What is the position of such persons?
Prabhupada: He’s most dangerous. He’s most dangerous. He is opportunist.
He’s finding out customer, something here… According to the customer he is
giving something, as the customers will be pleased.
