Torah study

I didn't understand, I read the above-mentioned opening in the past (according to your recommendation) and throughout all the chapters it talks about some kind of mystical connection, and when a person speaks words of Torah it is as if God is speaking, this doesn't seem like a rational explanation to me, and it may even be true according to Kabbalah. Mm, I'm asking about the second possibility I presented, what do you think?

I wrote my opinion. What's the point of going back again?

“I also said that a scroll should be written in the size of a book that is written in the size of a Torah business. Because even at the same time that a person is engaged in the Torah below, every word that comes out of his mouth, as it were, also comes out of the mouth of the Blessed One at that very moment. Because the supreme root of the Torah is in the highest, in the worlds called the worlds of the Endless, the secret of the invisible garment. Do you see a rational explanation here? I did not get it, I would be happy if you could help. In addition, “and even if he is engaged in matters of legend that do not have any legal basis, he is also stuck in the words of the Blessed One.” For the rational explanation, this is completely incomprehensible, and also, as I think I saw you write, there is no point in studying the matters of legend.

As you know, the definition of a rational explanation is: my explanation, to my epoch from other explanations.
I don't know what kind of explanation you expect. He claims that learning is adherence to the will of God and therefore adherence to Him Himself. Is that not rational for you? So no.
Indeed, in my opinion there is no educational value in studying a fairy tale, but as far as I understand, there is no special value either (because I do not accept that fairy tales are the work of God).

The Aggadatha also contain moral and encouraging words for keeping the Torah. Is this Torah study in the gebra?

In my opinion, such a thing is not study at all. Study is the acquisition of knowledge. The practice of virtue and observance of Torah is not study, and in any case it is not study of Torah.
