A wise zen frog was explaining to the younger frogs the balance of nature, "do you see how that fly eats a gnat? Now (with a bite) I eat the fly. It is all part of the great scheme of things." " Isn't it bad to kill in order to live?" asked the thoughtful frog. "It depends..." answered the wise frog just as a snake swallowed the zen frog in one chomp before the frog finished his sentence. "Depends on what?" shouted the students. "Depends on whether you're looking at things from the inside or outside." came the muffled response from inside the snake.
