The opening of this shiur, in Rabbi Daniel Glatstein’s own words — taken from the captions, so names and Hebrew terms may be approximate.

Recording stopped. Okay, friends. Perkey Avos, perek gimmel, pasuk ches. If you have a Perkey Avos, it's the Mishnah of Rabbi Dostai bar Yanai mishum Rabbi Meir omer. Rabbi Dostai, the son of Yanai, said in the name of Meir. And we'll see this is very appropriate to Rabbi Meir because Rabbi Meir had the Torah inscribed on his mind's eye. If you remember, the Gemara Megillah says that Rabbi Rabbi Meir once wrote a Sefer Torah by heart. And the Gemara asks, you're not allowed to. You have to write it from a previously inscribed Megillah. And the Gemara says, "No, Rabbi Meir is different. Rabbi Meir af al pe chacham yashir lefanekha. The Torah was written on the mind of Rabbi Meir. So, he for him it was considered like he copied it from a pre-existing Sefer copied it from a pre-existing Sefer Torah. So, what does the Mishnah in Perkey Avos say? Kasha shekeach davar echad mi mishnasav, if you forget something from your learning, mala alav hakasuv, it's considered ke'ilu miskayev benafsho.

And this is uh juxtaposed to the previous Mishnah that if somebody interrupts in the middle of learning and says, Ilan manua, Ilan zemi, I nua near zemi, mala alav hakasuv ke'ilu miskayev benafsho. Where do we learn this from? Shenemar, Where do we learn this from? Shenemar, rak hishamer lekha, be careful, ushmar nafshikha me'od, guard your soul, pen tishkach es hadvarim, lest you forget the matters asher rau einekha, that your eyes saw. Yakhol afilu takfa alav mishnasav, I would think that you're liable even if your learning became so overbearing and you became so overwhelmed and there were external forces that were causing forgetfulness, still you're liable to your life. No, talmud lomar, ufen yasuru milevavkha kol
