Green Speech #6
We have been showing how the Chofetz Chaim learns that not only does Loshon Hara cause the exile of God’s presence and the destruction of our temple but it is our Loshon Hara and a lack of Jewish Unity today and not that of the generation of 2,000 years ago that is still causing our exile and pushing away God's presence. .
We curse ourselves and make ourselves undeserving of redemption as it says “Cursed is he who attacks his friend secretly” (Devarim 27:24).
As Rashi explains, this is a reference to loshon hora. A person who speaks loshon hora is cursed. The Talmud (Arachin 15b) goes further, comparing loshon hora to a denial of G-d.
