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.)
Adam trudged past the gates of Eden, his head low, his heart heavy with the pain of remorse.
Suddenly he stopped. A thought had struck him.
He turned to the heavens and exclaimed, “You had this planned! You put that fruit there knowing I would choose to eat from it!”
“But tell me: Why?
The heavens were silent.
But we have found an answer.
Without failure, we can never truly reach into the depths of our souls. We cannot know that our choices matter, and that we hold our destiny in our hands. That we exist.
With that failure and that discovery, we can return to the garden, reaching higher and higher without end, to the One that exists without cause.
Beyond Eden.
