Tisha B'av - Understanding Sinas Chinam - Double Episode

The 2nd Mikdash was destroyed because of Sinas Chinam. What causes us to hate others, and how can we work on it? What are the parameters of Sinas Chinam, who are we obligated to forgive? Why is the Bar Kamtza story more an example of Sinas Chinam and concealed hatred then any of the other stories of cruelty and machlokes in that time? One of the most thought out shiurim I have prepared so far. It was a lot of material, so I split it into two clips. I think it's essential to think about, and I hope you find it meaningful. Thanks to all the people who helped with fleshing out this material, including Rabbi Yehuda Shmuelevitz, Rabbi Natan Lindell, Maor, Daniel, Dovid Tzvi, and the Kamin Kiddush Chaburah. Hope you have a meaningful fast. May we be zoche to the Binyan Hamikdash with the Bias Goel Tzedek Bimheirah Biyameinu Amen. This Episode is dedicated as a zechus for a Refuah Shelaimah for Yehuda Leib ben Rachel Chana
