DOES HASHEM DEMAND SUCH HIGH LEVELS OF TORAH LEARNING? [#16971]

The Rav has several shiurim (in the series on Nefesh HaChaim, Gate IV) on how everyone needs to form a really deep bond with his Torah learning, and if one isn’t inwardly connected to his Torah learning, he will be judged very severely in Heaven and he will be shown that his Torah learning isn’t worth that much in Heaven. How can the Rav imply that Heaven demands such high levels of Torah learning from this generation? The generation today is on such a low level and anyone today who learns Torah is probably very precious in Hashem’s eyes even if he learns totally shelo lishmah. Why the emphasis so much on “inner connection” to Torah study?
Also, are the Rav’s shiurim on Nefesh HaChaim Gate IV about learning Torah specifically geared towards serious kolel avreichim who seek perfection in their Torah learning, or are these shiurim even for people who aren’t found at such a high level of growth in their learning, who just simply want to enjoy their learning and be successful in their learning, but who are not necessarily seeking more truth and more growth in their learning?

Every person is obligated to form a deep inner connection to his Torah learning according to the level that he’s capable of. As for how much Heaven will hold a person accountable for how much Torah he could have learned or not, that is something that cannot be written in a response, because each person is at a different level.
The shiurim on Nefesh HaChaim Gate IV are meant for anyone to listen to, but only a few individuals are meant to do the actual work contained in these lessons.
