Tanya Chapter 34 part 1

The Patriarchs were the Divine chariot, never breaking focus from the Divine unity. And this was true to varying degrees about each of the prophets, most notably our teacher Moses. As a whole, the Jewish people experienced something of this Divine revelation at the giving of the Torah, but they did not have the mental and soul capacity to bear it; their souls left them. Instead, Hashem told them to build a physical space in this world where the Divine would be totally manifest –– the Sanctuary. Ever since the Temple was destroyed, the Divine will and wisdom is revealed within the four cubits of Halacha. And when we establish fixed times for Torah study, this Divine manifestation comes through us, and each of us becomes a Sanctuary, a host for the Al-mighty Himself.
