Our service for Krishna is voluntary and can never be forced. And whatever position in life one holds he can serve Krishna in that way. But yourselves being such qualified and experienced preachers, what is the benefit of engaging in the second-class activity when there is so much preaching work to be done? Practically speaking, our Krishna philosophy will save the whole world from the most dangerous condition, that is a fact. So now you just become convinced yourselves of this fact and help me spread this Movement for saving the world with all conviction and attention, and in this way you will be performing the highest type of activity and very soon you will go back to Home, back to Godhead, know it for certain.
Letter to Vamanadeva and Indira dasi, 8 December, 1971
