At sunset in the forest Notire Basura came upon a monk who was about to make a meal of a hare which he had roasted over a small fire. 
Inviting Notire to share his repast, he asked, "Tell me, venerable sir, is it evil to dine upon one's fellow creatures?" 

"You cannot live a day but at the expense of the lives of other creatures," Notire replied. 
"In each moment of your life your body kills and absorbs the bodies of innumerable living creatures who, but for the diligence of your unconscious body, would kill and dine upon you. The lion eats the jackal; the jackal eats the fox; the fox eats the mouse, and the worms eat them all; and no doubt beasties smaller yet eat the worms. 
If killing for food were evil, all would eat grass. " 

The monk was enlightened.
