“Instead of contemplating what will happen to this world, you have got a short duration of life, say fifty, sixty years. You chant Hare Krsna and go back to home, back to Godhead. Don’t consider what will happen to this world. Nature will take care of it. You don’t puzzle your brain with these thoughts. You utilize whatever time you have got in your possession and go back to home, back to Godhead. You cannot check it. Best thing is that you mold your life and go back to home, back to Godhead. Because people will go on with their rascal civilization, natural consequences will be there. You better take advantage of whatever time you have got and become fully Krsna conscious and go back to home.”[Srila Prabhupada, Morning Walk, February 21, 1975, Caracas]
