Don´t worry what is going on in the world!
Srila Prabhupada on morning walk, Caracas, Feb 21, 1975
"Instead of contemplating what will happen in the world - you have a short duration of life, say fifty sixty years – you should chant Hare Krsna and go back home back to Godhead. Don´t consider what will happen to this world. Nature will take care of it.
Don´t puzzle your brain with these thoughts. You should utilize whatever you have in your possession and go back home back to Godhead. Oil your own machine, instead of thinking what will happen elsewhere. (These things) will happen. Because people will go on with their rascal civilization, natural consequences will be there. Better you take advantage of whatever time you have got, become fully Krsna conscious and go back to home."
