Here life comes to its end. A man's work stands completed. The path rises high toward heaven, like the flight of wild geese when they have left the earth far behind. There they fly, keeping to the order of their flight in strict formation. And if their feathers fall, they can serve as ornaments in the sacred dance pantomimes performed in the temples. Thus the life of a man who has perfected himself is a bright light for the people of earth, who look up to him as an example.
