The approach to learning in this post does not exactly correspond to the approach to learning in the Yeshivot. To reconcile the two, one can say that the learning of Halacha is to occupy oneself with Torah, so that ultimately the Keitz will be found. One could then say that learning of Kabbala is higher mainly because it interprets the Torah more freely so that the chances are higher that the Keitz will be found.
What is the Keitz? Again, I refer to this post. Once it is recognized, also the other Keitz will be recognized.
The learning of Halacha and Kabbala is surely important, but the ultimate purpose is the Keitz and all that follows.
