Chofetz Chaim Daily 7 Shvat. Intro. One should try to fully understand the laws, not just superficially, because one might misinterpret heterim. By studying the laws, one will not become a baal LH. A baal LH is similar to one who transgresses a cardinal sin (see 27 Shvat 1:4 “as bad as all 3” !) & doesn’t greet the shechina.
Chofetz Chaim Daily 2 Shvat. LH is the primary sin we need to rectify to merit redemption because 1)it caused the current exile 2)the LH of the miraglim also caused exile 3)LH prolonged the Egyptian exile 4)the Torah curses LH sinners 5)A Baal LH is equal to a kofer. See sefer for elaboration.
Chofetz Chaim Daily 3 Shvat Some reasons why LH is so terrible 1)When people speak/listen to LH, the satan gets the ability to prosecute & the heavenly court gets the right to listen to sins 2)LH damages the potency of prayers and Torah learning that comes from the mouth 3)LH is a habit that piles up many sins very quickly
