This forms the basis of the type of fast learning that all authentic Litvak yeshivas do in the afternoon and I showed how this comes from the Talmud itself. לעולם לגרס איניש אע''ג דמשכח ואע''ג דלא ידע מאי קאמר
I mentioned this in reference to Tosphot --just to say it over day after day, even for months until you understand.[Unless you are learning with a learning partner. In that case you do this kind of learning on your own time.]
But also this applies to learning Gemara, and Tur, Beit Joseph. To put a place marker in the book and every day do one whole page in order, and the next day to go on from where you left off.
I wanted to add the idea of learning standing. This is also a great help to understanding. I remember that this was how I did a lot of the writings of the Ari(zal), Isaac Luria. I did not have "Stender" at home so I pulled out the shelf of one cabinet and stood up learning the Ari. [Not during "seder" or regular yeshiva hours 10:00-2:00 4:00-8:00]
This should not be taken as a kind of agreement with the Ultra Religious who are insane. This should only be taken as agreement with Lithuanian yeshivas where Torah is learned for its own sake. Nothing else in the religious world do I consider kosher at all. [In fact the Gra knew exactly what he was doing when he signed the Cherem and it is wrong for people to ignore it, because it relates to objective reality.] This affected the entire frum world including the yeshivas. Even the yeshivas have gotten a share of the kelipot that penetrated into them. They will make a song and dance around secular Jews that have money but treat other people like dirt.
