When I looked at the 13 stories of Rav Nachman of Breslov about the smart son and the dumb one, I noted that the dumb son really was dumb, and yet by the trait of simplicity, he became smart; and that the smart son even though he was in fact smart, in the end he became stupid. Thus, I think we can see here an amazing bit of advice about how to go about learning. I have noticed in my own learning, that if I concentrate on understanding, I usually lose the big picture, and often I even lose the understanding of what I am learning by over doing it. It seems to me, I learned a lot more by the method of the simple son,--that of simplicity--just say the words of what I am learning and go on. However, when it comes to learning in depth, I do find it important to have at least one session of in-depth learning. THIS I find in my learning of gemara and in physics and math also, -------When I was in the Mir Yeshiva in N.Y. the main learning was in depth, and yet in the afternoon I went through Gemara pretty fast,—not very fast but not slow either. Then in Israel, I spent a lot of my day in prayer, and then when I got home after the evening prayer, I would go though a lot of Gemara. Then in Uman where I learned with David Bronson, the learning took a turn, and I started learning in depth again. Thus, I find it important to have what is called in yeshivot "Bekiut and Iyun", a fast session and an in-depth session
