"Then the L-rd your G‑d will return your captives from exile, and He will have mercy upon you. He will gather you again from all the nations where the L-rd your G‑d had dispersed you" [Deut. 30:3]

The Baal Shem Tov taught on this verse:

..."Adam" is an acronym for the names "Adam, David, Moshiach."

Every single Jew must perfect and make ready the part of the Moshiach that relates to his own soul. As it is known, the word "Adam" is an acronym for the names "Adam, David, Moshiach." Adam's size was from one end of the earth to the other, and included in it all the souls of Israel. After the sin of eating the forbidden fruit, however, his stature was diminished. Like Adam originally, Moshiach's soul will be made up of all the 600,000 souls of the Congregation of Israel, as it was before Adam's sin.

Therefore, every Jew must make ready that portion of his own soul that corresponds to that of Moshiach until the entire structure of the worlds is fixed and established. Then there will be a universal Unification, without end. May it be soon in our days!
