Based on the Dvar Malchus of the Shabbos Parshas Titzave 5752
Rabeinu was also born on that same day. Moshe Rabeinu's and therefore the entire Jewish nation's mazal become very strong on that day.
We really don't need Adar's mazal, because Moshe Rabeinu's and our mazal nullify Haman's decree. The month of Adar then offers us only good and blessing.
With all of their might
"Mazal" is something that refers to the stars in the heavens that help a person. We Jews don't have anything to do with stars, for our "mazal" doesn't come from them. A person's "mazal" refers to his etzem haneshama, the deepest part of the soul that is always bound and connected to Hashem, and because of it, a Jew can never become detached from Hashem.
On Moshe Rabeinu's birthday, our mazal also becomes stronger. On that day every Jew's connection with Hashem becomes stronger and more powerful, wishing to be closer and next to Hashem no matter what. This is what happened on Purim, when we had mesiras nefesh (we were willing to give up our lives) in spite of Haman's decree, in order...
The leader of the generation's birthday
A person's mazal becomes stronger on his birthday. It helps him more than usual. The 7th day of Adar is Moshe Rabeinu's birthday. On that same day the mazal of the Jewish nation also becomes stronger. This is because Moshe is the leader of the generation. Whatever happens to the leader happens to all of us.
The Midrash tells us that when Haman the evil one drew lots in order to determine when to destroy the Jews, he realized that every month had its own zichus that protected the Jewish nation. He thought that the month of Adar had no zichyos (merits) and as a result was very happy. Furthermore, he knew that the sign in the heavens for the month of Adar, fish, also didn't offer any mazal for the Jews. Therefore, he thought that this month would be a good time to wage war against the Jews. He was also aware of the fact that Moshe Rabeinu passed away on the 7th day of Adar.
Haman's mistake, however, was that he didn't know that Moshe Rabeinu was also born on that same day. Moshe Rabeinu's and therefore the entire Jewish nation's mazal become very strong on that day.
This is what the 7th day of Adar is all about, the birthday of the leader of our generation. Each and every one of us is given strength to study Torah and fulfill the mitzvos with all of our might while being happy.
It started in Adar and finished in Nisan
The month of Adar was only the beginning. Purim is in this month, a time of Hashem's miracles and wonders. Yet after the miracles this terrible and difficult golus continued.
The Torah teaches us that "...In the month of Nisan we were redeemed from Egypt, and we will be redeemed then in the future..." The month of Nisan relates to the third redemption, after which there will never be an exile again, and the third Beis Hamikdash. The Rebbe stresses that on the 11th day of Nisan, Hashem reveals Himself in order to make for Himself here in this world a home to live.
In summary, on the 7th day of Adar, the birthday of Moshe Rabeinu, the first redeemer, every Jew is given the strength and might from Hashem to do his job in the world. In the month of Nisan, especially on the 11th day of Nisan, we finish our spiritual job, followed by the true and complete redemption.
The "tachlis", the bottom line, not to give up our Torah and mitzvos.
Based on the above, we can understand the meaning of the month of Adar. The words Adar and Adir in Hebrew look alike, and as such share a similar meaning - might. The month emphasizes and describes what a Jew really is, strong and mighty.
The Rebbe Melech Hamoshiach Shlita stresses that the purpose of creation was for us, a soul within a body, to make a home for Hashem in this world. Therefore, when we mentioned above that the Jews were willing to even give up their lives rather than Torah and mitzvos, we didn't mean that they actually gave up their lives.
The same applies to us. Hashem wants us to be in this world, with healthy souls and bodies. A Jew's strength and might can then be revealed and seen in the world.
That's the way it was on that first Purim. When the Jews were ready to give up their lives, they didn't actually die. What did happen was "vinahafochu". Hashem overturned Haman's wicked plans. The Jewish nation was victorious against their enemies. They killed them. They studied Torah and fulfilled the mitzvos happily and with all of their might, all in the spirit of good health.
is to bring about the redemption
As always, the Rebbe Shlita Melech Hamoshiach teaches us how to actually apply all of the above to our daily lives.
"...We should increase and add more energy in whatever we do in our service to Hashem when it comes to the study of Torah and the fulfillment of mitzvos, including and especially the dissemination of Torah, Judaism, and the wellsprings to the furthest places possible, in order to bring about in a revealed manner to everyone the true and complete redemption by our righteous Moshiach..."
What the Rebbe tells us to do is clear, simple, and to the point. We should add in everything that we do, especially when it comes to mivtzaim, in order to bring about the redemption. All that we learned about giving up our lives and doing Torah and mitzvos with all of our might should be channeled into one direction - to bring about the true and complete redemption!
Once this is done, the Torah teaches us what will take place next, in next week's parsha, ... The first letters of the 3 words ... is ... Hashem will appoint the Rebbe as the head of the Jewish nation, the Melech Hamoshiach who will come and redeem us as soon as possible, immediately!
