The battles fought between the Jews and their enemies, which took place on Adar 13 throughout the Persian empire (see "Today in Jewish History" for that date), continued for two days -- Adar 13 and 14 -- in the capital city of Shushan, where there were a greater number of Jew haters. Thus the victory celebrations in Shushan were held on the 15th of Adar, and the observance of the festival of Purim was instituted for that day in Shushan and all walled cities. (See Laws and Customs below).
On this date, in the year following the Holy Temple’s destruction, G‑d tells Ezekiel to take up a lamentation for Pharaoh, king of Egypt, and for the Jewish nation’s other enemies, foretelling their ultimate downfall.
Read the prophecy here: Ezekiel ch. 32
In cities that are surrounded by a wall dating from the days of Joshua (13th century BCE) -- a prominent example is the city of Jerusalem -- the festival of Purim is observed on the 15th of Adar (instead of the 14th), in commemoration of the fact that in the ancient walled city of Shushan, the first Purim was celebrated on this day (see "Today in Jewish History").
All over the world, Tachanun is omitted due to the special joy of the day.
(For an overview of the Purim observances and links to more information, see "Laws and Customs" for Adar 14.)
G‑d said to Abram, “Go to yourself, from your land, from your birthplace and from your father’s house, to the land which I will show you.”—Genesis 12:1
If you were not you, if you saw yourself from the eyes of another, how would you see your journeys through life?
You would see how each journey leads away from home. Away from your birthplace, from those who nurtured you and that which made you what you are. Outwards, away from yourself in so many directions.
But you see your journey from within. From within, every journey leads in one direction: Towards within. Towards yourself. Closer and yet closer.
To the land in which G‑d shows you yourself.
