Laughing turns to crying

A man showed a compass to Nasruddin and asked him what it was. Nasruddin immediately began laughing. But just seconds later, he began crying.
The man noticed his bizarre behavior, and asked, “What was that? Why did you start laughing few seconds ago, and then all of a sudden start crying?”
“At first,” Nasruddin responded, "“I laughed at you because you didn’t know what that object was; but then I realized that I didn’t know what it was either, so I cried.”


Most do not even realize that we also do not know the path of Knowledge. We keep laughing at others. If we even come to realize the real way then we would cry on our laughing at others.
