Anything is one of a million paths. Therefore, a warrior must always keep in mind that a path is only a path; if he feels he should not follow it, he must not stay with it under any conditions. His decision to keep on that path or to leave it must be free of fear or ambition. He must look at every path closely and deliberately. There is a question that a warrior has to ask, mandatorily: Does this path have a heart?
All paths are the same: they lead nowhere. However, a path without a heart is never enjoyable. On the other hand, a path with a heart is easy–it does not make a warrior work at liking it; it makes for a joyful journey; as long as a man follows it, he is one with it.
