In this remarkable Derech Hashem shiur, Rabbi Shafier explores not only the hidden mechanics of nevuah, ruach hakodesh, and how Hashem reveals knowledge to man, but also the staggering inner world of Moshe Rabbeinu and Aharon HaKohen. What emerges is a portrait of greatness that is almost hard to comprehend: leaders so pure, so selfless, and so elevated that even the offer of ultimate spiritual access could be turned down rather than cause another Jew pain. Listen to this shiur to deepen your understanding of nevuah, sharpen your appreciation for Chazal and the gedolei Yisrael, and walk away with a far bigger vision of what true greatness looks like.
