I’ve heard this story on the second day of Yom Tov (Wed.) from one of the rabbis in Brooklyn:
Every year, chassidim would wish the Rebbe that “the Rebbe should be alive next year”. To which he would respond: “gam atoh” (“you too”). One year, a chossid came to the Rebbe and wished/asked him that “the Rebbe should reveal himself”. Meaning, of course, that the Rebbe should reveal himself as [who he is]. To which the Rebbe responded: “gam atoh”.Those of understanding will understand.
This can be explained as follows. Every person has the deepest potential of who he is in the essence. The chossid wished the Rebbe that he reveals this deepest potential and his true and deepest role. While the Rebbe, in his turn, wished the chossid that he does the same, regarding himself.
So, what is the deepest essence of every Jew? In Tanya we learn that every Jew is “cheilek elokah mi’ma’al mamosh” — a part of G-dliness Above literally.
