Look at every 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. Now I do understand it. I will tell you what it is: does this path have a heart? If it does, the path is good. If it doesn't, it is of no use.
