Chofetz Chaim Daily New Cycle. 1 Tishrei. Introduction. Praised is Hashem who gave us the Torah, and brought us into Eretz Yisrael! Alas, at end of Bayis Sheni, Sinas Chinam and LH forced us into this long and harsh exile*. Hashem is ready and able to redeem us; He is waiting for us to do teshuva.
Chofetz Chaim Daily 2 Tishrei. 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 Tishrei 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
* although clearly the redemption process is well underway, we still anticipate its completion B’Karov BiYameinu. -ed
