Purim is about us Jews being one.
We gather at night and by day to hear the Megillah—because it is the story of all of us.
We send each other gifts of food—because we are all friends.
We send gifts to needy Jews—because their needs are our needs.
And we make a feast together—because we are one.
The Purim Scroll of Esther, conveys a profound message:
When the Jewish nation don't live by the laws of unity, there will appear plenty of Hamans to destroy them.
The law of the nation declared at Mount Sinai, was based on unity. A mutual responsibility to care for each other. This bond generates the positive force, G_d's presence between them. No harm can penetrate this unity.
When these 'certain people' become scattered and dispersed' as the evil force, Haman declared to the king who symbolizes G_d, they are vulnerable to attack.The nation had disobeyed their fundamental law of unity.
This special unity is the light that must radiate to humanity. Without this light this nation is unnecessary. They can't be a light to the nations of the world.
Harm to the Jewish nation is a reflection of their unity. The divine bond of mutual love must be reinforced within our minds and hearts. Thoughts and feelings have no boundaries.
Keep this Purim message of unity before you, always.
