1. University professors as croaking frogs

    The education cultivated by so-called learned scholars who do not believe these statements of Sri Caitanya-caritamrta is like the tumultuous croaking of frogs. The croaking of the frogs in the rainy season resounds very loudly in the forest, with the result that snakes, hearing the croaking in the darkness, approach the frogs and swallow them. Similarly, the so-called educational vibrations of the tongues of university professors who do not have spiritual knowledge is like the croaking of frogs.
