I warn you. Look at each path closely and deliberately. Try it as many times as you think necessary. Then ask yourself, and yourself alone, one question. This question is one that only a very old man asks. My benefactor told me about it once when I was young, and my blood was too vigorous for me to understand it. I will tell you what it is:
~Does this path have a heart?~
The trouble is nobody asks the question; and when a man finally realizes that he has taken a path without a heart, the path is ready to kill him. At that point very few men can stop to deliberate, and leave the path.
For me there is only the traveling on paths that have heart, on any path that may have heart. There I travel, and the only worthwhile challenge is to traverse its full length.
And there I travel,
looking,
breathlessly.
