Srila Prabhupada Cites Cowper
1969 June 24 : "I am always thinking of your New Vrindaban. The milk which we are taking here is not at all comparable with New Vrindaban milk. As poet Cowper said, 'Country is made by God, and city is made by man.' Therefore, my special request is that you should try to maintain as many cows as possible in your New Vrindaban."Prabhupada Letters: 1969
The key thing is a rational understanding of what is “possible”, something that was sadly lacking back in the day in NV. Despite any past misapplication of the above suggestion, the underlying thought is solid, and should be followed.
