According to tradition, Moses was born on the 7th of Adar I, today was the 8th day of his life and the day on which he was circumcised in accordance with the Divine command to Abraham.
In regular years, the 14th of Adar is Purim, the festival that celebrates the salvation of the Jewish people from Haman's evil decree in the year 3405 from creation (356 BCE). In a leap year -- which has two Adars -- Purim is celebrated in Adar II, and the 14th of Adar I is designated as Purim Kattan, the "Little Purim." There are no special observances, however, associated with Purim Kattan, other than the omission of Tachnun ("supplications") from the daily prayers and a prohibition against fasting or holding eulogies on this day. The Code of Jewish Law cites an opinion that one should increase in festivity and joy, but rules that there is no obligation to do so; "Nevertheless,a person should increase somewhat in festivity... for 'One who is of good heart is festive always' " (Shulchan Aruch, Orach Chaim 697:1).

Why is Torah compared to light? Because it tells us the place of each thing.
Because, in truth, there is no need to change the world. Everything is here.
Each thing has a place, and in that place it is good. Altogether, it is very good, a beautiful world. All that’s needed is a little light.
What is light? Light doesn't add anything or take away. It only reveals the meaning and purpose of all that it shines upon.
Think of your own home. In the dark, there is no way to know what belongs in your closet and what belongs in the laundry, what is ready for use and what is in need of repair. Instead, that which could be washed or repaired is rejected and despised, and your most valuable possessions may become the greatest hazards.
Switch on one little light and a dangerous place becomes a home. With every light you add, you become suddenly wealthier and more blessed.
So too, this world is meant to be G-d’s home. Torah is light. Shine it bright and heal the world.
