Answer:
Polonius reads the love letter aloud to Gertrude and Claudius for two reasons:
He wants to show that he is a loyal subject, and that he's not trying to get his daughter together with Hamlet—Hamlet, being a royal, won't get much advantage from marrying the daughter of a mere noble. If he reveals the message to them directly, they'll know he is "a man faithful and honorable," as Claudius says.
He wants to get credit for being the one to know why Hamlet is mad. Once he reads the letter, he uses it to explain how Hamlet became mad: "he, repelled...Fell into a sadness, then into a fast...and, by declension / Into the madness wherein now he raves." Claudius was very eager to find out why Hamlet was mad, so being able to give an explanation makes Polonius look good.
His plans after reading the letter are to show the king directly that love is the cause of Hamlet's madness by taking the king to observe a conversation between Ophelia and Hamlet. As it turns out, Hamlet is very mean to Ophelia during this conversation, and the King concludes that he is not in love: "Love? His affections do not that way tend." So Polonius's plan doesn't really succeed.
<span>A Hasidic legend tells us that the great Rabbi Baal-Shem-Tov, Master of the Good Name, also known as the Besht, undertook an urgent and perilous mission: to hasten the coming of the Messiah. The Jewish people, all humanity were suffering too much, beset by too many evils. They had to be saved, and swiftly. For having tried to meddle with history, the Besht was punished; banished along with his faithful servant to a distant island. In despair, the servant implored his master to exercise his mysterious powers in order to bring them both home. "Impossible", the Besht replied. "My powers have been taken from me". "Then, please, say a prayer, recite a litany, work a miracle". "Impossible", the Master replied, "I have forgotten everything". They both fell to weeping.</span>
If the question is how are they related, it is a total comparison.
