Pradyumna: “In the midst of the ocean, such volcanic eruptions can do very little harm, and similarly, those who are against devotional service to the Lord and who put forward many philosophical theses about the ultimate transcendental realization cannot disturb this great ocean of devotional service.”

Prabhupada: That sometimes, everyone knows, there is volcanic eruption in the ocean. What does it harm to the ocean? It throws out some lava, and some little island may come out, but what is the harm to the ocean? Similarly, these rascal may go on with their philosophy for killing Krsna. That does not hurt Krsna consciousness movement. It will go on. This ocean will never be disturbed by these so-called philosophies.
