What is the secret to joy? How do we achieve exuberant happiness? Is it about remembering only happy things and having only happy thoughts?
Who is our greatest enemy? What is the most powerful impediment to finding happiness and joy?
Interestingly enough, the first question is answered by the second: The key to achieving bliss is remembering your mortal enemy.
This Shabbat, which precedes Purim, is called Zachor. And it is all about remembering the biggest threat to our lives so that we may obliterate it and achieve true joy.
Some 2,900 years ago King Saul did not obliterate Agag, the Amalekite king. As a result, the Amalekites proliferated, and Haman, the villain of Purim, was born 500 years later.
It took Mordechai, a descendant of Saul, to finish off Haman, a descendant of Agag.
Amalek represents doubt and apathy. This is the greatest threat to the Jewish people.
It is our mission and obligation to obliterate all doubt and uproot all apathy.
And this leads to the immense and complete joy of Purim.
