This might seem difficult to understand but perhaps I can make it clear. It seems to me that God has blessed humanity with a few great books. Each one is important but does not have all the truth about people and life. But rather some aspect of truth. To me it seems the one on the top of the list is the Torah (The Old Testament).
There are two approaches to Talmud. One is the present day way which began with R. Chaim Soloveitchik. I must say that I did not learn this way personally. I heard many lessons along the lines of Reb Chayim. But when I got back to my shtender "seat" I plowed through the Talmud with the Tosphot and Maharsha and the early "achronim" (later authorities like the Pnei Yehoshua). Sometimes I would go over and over a Pnei Yeshoshua about ten or more times until I got it.
But even this way could not be called traditional. The traditional way of learning was different. The principles were these: (1) Learn Tosphot. (2) It is forbidden to add any so called principles to make Tosphot make sense. He wrote it to make sense on its own. If you have to add outside concepts, then you don't understand it. [Sadly, most people are taught that you don't understand it unless you add some outside principles. So they spend the whole day making up nonsense, and they call it "learning" and think that people that don't do this idiocy can't learn.] (3) There is a point that you get to when you understand Tosphot that something comes up almost by magic. Some thought or question. It is that magical point that is called "Learning." For me it is very hard to get to that point.
The way of Reb Chayim Soloveitchik was different. He did add yesodot יסודות or principles, but from elsewhere in the Talmud itself. And he did it in a way that does fit.
The major school of thought of Reb Chaim [Chidushei HaRambam] continued through Baruch Ber (the Birchat Shmuel), Shimon Shkop, and the most difficult of all- Rav Eliezer Menachem Shach of Ponovitch (that is his book the Aviezri).
These four constitute a whole and complete set by which it is possible to understand the Rambam.
No home is complete without them.
