Answer: Haman is the force that divides us and thereby weakens the nation so that it is easier to manage us. In the Book of Esther, Haman told king Ahasuerus, “There is a certain people scattered and separate among the peoples throughout all the provinces of your kingdom…”; they are weak because they are divided, and therefore it is easier to destroy them.
This is the reason that we must unite above all of our differences, including every part in the nation, in spite of everything that divides us, without any arguments as to who is right.
The wisdom of Kabbalah is directing us toward this unity, to unity above all of our differences, so that, as it is written, “Love covers all transgressions,” since this is the only kind of unity that there can be in the nation of Israel, which otherwise would remain as a gathering of exiles, as a collection of immigrants from different counties.
Haman is the force that tears the Jewish nation into pieces. We can identify him in every part of society, religious and secular, left and right political streams, etc. Kabbalah is the method of uniting opposites, above all rejections. It is the only method that has the force of correction, the force of Esther and Mordechai.
