THE RABBIS' MORAL, PSYCHOLOGICAL and PHILOSOPHICAL INSTRUCTION for HUMAN PERFECTION Throughout the 1980s, Rabbi Israel Chait gave 130 lectures on Pirkei Avos. These lectures were recently transcribed verbatim from the original audio and edited. Rabbi Chait unveiled volumes of astonishing insights into the Rabbis' commentaries on the Mishnaic Sages, including Maimonides, Rashi and Rabbeinu Yona. Having attended these lectures 35 years ago, and transcribing and editing them now in 2017, I can say that the ideas contained in this series of books are marvels of wisdom and delight the soul, they are crucial ideas on our path towards human perfection, and they must not be passed up.
