We read it’s impossible to curse the Jews because it’s Baruch. What does that mean? It sounds as: you can’t damage this car as it’s in perfect state.
Baruch is typically translated as Blessed. That is beyond questionable. It’s plain wrong. Baruch is related to the word Bereichah, the spring of a river. Baruch means the Source of all blessings.
A standard Hebrew ‘blessing’ begins with the word Baruch. It says: You are the Source of all blessing, G^d, G^d of ours, Ruler of the Universe, …
The Sages explain that enjoying this world without saying a ‘blessing’ is like stealing from G^d. Before uttering the ‘blessing,’ everything is G^d’s; after it, G^d gives it to us. How could that ever work? “Where’s my wallet?” “Oh, I blessed you and then I took it.” It can’t work like that with people.
But, when we directly talk to G^d (don’t act behind His Back), and actually acknowledge Him as owner, He says: Thanks, kids, enjoy it.
A Hebrew ‘blessing’ is not a Thank You, a Please, or a You are Great, but rather a testimony of His ownership. And when we say Amen to it, we need to do that out loud because it’s not a Prayer. It’s a testimonial too.
Jews are Baruch means that G^d’s goodness is showered on the world via the Jews’ worthiness. If you remove the Jews from the equation, G^d’s goodness will not descend anymore for anyone. You can take away the Jews’ Baruch because everyone’s life will only know suffering.
Levarech, the verb with Baruch, means: to acknowledge who’s Baruch.
To curse then means: to deny who’s Baruch.
When you acknowledge that the goodness in the world comes through the Jews, you will also become Baruch, enabling goodness in life.
When you curse the source of blessing, you become part of the problem.
