In the South American rain forest, there is a tribe called the Desena, who see the world as a fixed quantity of energy that flows between all creatures. Every birth must therefore engender a death, and every death bring forth another birth. This way, the energy of the world remains complete.
When they hunt for food, the Desana know that they animals they kill will leave a hole in the spiritual well. But that hole will be filled, by the souls of the Desana hunters when they die. Were there no men dying, there would be no birds or fish being born. I like this idea. Morrie likes it, too. The closer he gets to good-bye, the more he seems to feel we are all creatures in the same forest. What we take, we must replenish. “It’s only fair,” he says."
