Jewish secret doctrine

So does the Rabbi believe, as Leibowitz does, that the mitzvot are simply given and that's it? And if so, what do I care that 3,000 years ago some being gave a few freed laborers on an average-sized mountain a book of laws that no one is capable of understanding?

I really disagree with Leibowitz. I'm just arguing that although the commandments have reasons and motives, they are not accessible to us. This is not an a priori determination, but rather what comes to my mind from observing the suggestions that appear in the books of commentary and from my understanding of Kabbalah.

I can understand the inaccessibility of this or that particular mitzvah, for example, that the taste of mixing dishes has disappeared from our sight, but why, as if by some a priori necessity, is the entire field of the question of what the mitzvahs are about hidden from those who seek them? What causes us not to even be able to say whether the tastes of the mitzvahs are in the higher worlds of winged messengers, in the equations of Hamilton and Lagrange's analytical mechanics, or perhaps in the field of magnificent Akkadian statesmanship? There are many reasons for this (if, for example, the tastes of the mitzvahs are in the field of ancient culture and its customs, then we who do not live in it can free ourselves from this burden, whereas if we are talking about floating worlds, then the obligation still remains).
