Short Machshava On The Daf by Rabbi Yechezkel Hartman
A short Machshava on the Daf Yomi. Each Daf in Shas has Machshava depth to it, in some it's easy to find - the Agadata of the Shas, but in some it takes some research. Short Machshava shiur aims to discover, discuss in short, and attempt to give somewhat of an understanding of parts of the Machshava of each Daf. Given by Rabbi Yechezkel Hartman, a Talmid of Rabbi Moshe Shapiro zt"l.
