Tamala Krsna: Sometimes the devotees question that the Kali-yuga is advancing, and in that sense the standards are deteriorating. Yet you are preaching that “Get everyone to the position where everyone is Krsna conscious.” How in the Kali-yuga advancing can everyone become Krsna conscious?

Prabhupada: They do not understand. If I say, “The epidemic is increasing. You take this injection, then you can be saved. If you don’t take vaccination, then you’ll suffer,” this is our propaganda. “You take this vaccination; you’ll be saved. The epidemic is very strong.” But if you think, “Now, because there is epidemic there is no other way. What is the use of taking vaccination? ” this is no argument. The epidemic is there; the vaccination is there. The disease is there; the medicine is there. So intelligent man should take the medicine, precaution, and then he’ll be saved. Two things are there. Kalau nasty eva nasty eva gatir anyatha. In Kali-yuga, if you don’t take this, then there is no means of your save, safety. The two things are there. Why you are taking one thing? You take this thing or… [break] Everywhere two things are there: do’s and don’t’s. So in order to make the process of do’s you have to accept the process of don’t’s. That Nectar of Instruction, Rupa Gosvami? He’s instructing both the do’s and the don’t’s.
