Mesilas Hamaharsha - Pirkei Avos מסילת המהרש״א - פרקי אבות

Rabbi Eliezer Ginsburg, Rosh Kollel of Yeshivas Mir, has combed the Chiddushei Aggados of Maharsha and turned them into a commentary on Avos, complete with his own brilliant explanations and comments. The result is a "new" work with the full text of the Maharsha's comments, compiled and clearly explained, in Hebrew, including the text of the Mishnah.
