@EchadHaemes I’m repeating myself, but you seem to be unaware how uniquely Chabad-centric your view point is.
First and foremost, the Lubavitcher Rebbe’s Sichos were not meant to be learned b’iyun. He would have much preferred if his Torah would take a distant fifth place behind Gemara, Rishonim, Acharonim, and Halacha. Second, again, you have Gedolim like Rav Ruderman ZT”L who had the capacity to see more b’iyun in a “casual” reading of Torah than anyone alive can do in weeks, who learned Chabad Torah (Rav Ruderman was from a Lubavitch family and had daily sedorim in Tanya and other sifrei Chabad), learned the Lubavicher Rebbe’s sichos, and still didn’t see them as deep as some young bachur straight from Tzfas seems to see them. And he’s far from the only Gadol who did.
Have you learned Alei Shur? Pachad Yitzchok? Rav Hirsch? RAMCHAL? There are hundreds of sifrei hashkafa, most of which you’re probably unaware of. Who’s to say that learning b’iyun any of those wouldn’t have a similar epiphany that you achieved from one Gadol alone?
