I'd like to share a very poignant story from the Yerushalmi Talmud (tractate Taanis) with you, that took place in Roman-controlled ancient Israel of about 1800 years ago:
The Land of Israel was undergoing a severe drought. Rabbi Abahu, one of the country's most pious sages, had a dream. A voice from Heaven told him, "If you ask Pentakika to pray, then rain will fall." The next morning, Rabbi Abahu sent emissaries to locate and summon Pentakika immediately.
Within a short while, Pentakika came to Rabbi Abahu. "Tell me about yourself," the rabbi requested.
"I'm not much," replied Pentakika. "In fact, you'd probably consider me a lowlife; I'm the custodian of a brothel, and when I'm not cleaning the place up or taking their clothes to and from the bath house, I appear with the hookers on stage and play a drum while they dance and perform. When I'm not doing that, I just entertain them."
"Pentakika," the rabbi urged, "there's more to you than that, isn't there? Are you sure that you never did some very special deed?"
Pentakika scratched the stubble on his face, and pondered Rabbi Abahu's question for a moment. "You know rabbi, there is something I remember: Not long ago, a young Israelite woman came backstage on the brothel theater, crying her eyes out. I asked her why she was so distressed. She told me that the Romans jailed her husband, and that she needed money to gain his release. The young lady barely had money for bread and water; the only way she imagined to raise money for her husband's release was by selling herself to prostitution. I saw that she was an innocent young wife from a good home, so I wouldn't allow her to entertain such a thought. I therefore sold my bed, my mattress, and my pillow, and gave her the money. She arranged her husband's release the same day..."
"Aha," said Rabbi Abahu, "you are surely worthy of having your prayers answered, for your deeds are purest altruism."
Oftentimes, society turns its nose up at what it considers to be 2nd and 3rd cl
ass citizens. Kids on the street jeer and throw banana peels at down-and-outers, and their parents merely snicker. Careful, though, you never know - Mr. Bo Jangles the hobo could be a tzaddik nistar, a righteous saint in disguise. The Talmud therefore warns us to never hold another human in disdain; no one can know the true inner value of a person.
Don't ever forget that Mr. Bo Jangles also has a divine soul that's a tiny spark of The Creator. That in itself is sufficient reason to treat him - and every other human - with respect.
