Therefore you must always keep in mind that a path is only a path; if you feel you should not follow it, you must not stay with it under any conditions….

Does this path have a heart? If it does, the path is good; if it doesn’t, it is of no use. Both paths lead nowhere; but one has a heart, the other doesn’t. One makes for a joyful journey; as long as you follow it, you are one with it. The other will make you curse your life. One makes you strong; the other weakens you.
