Tanya Chapter 36: Why was it all created? There's a purpose. part 1

Hashem has a desire to dwell in these lowest realms. In order to understand the scope of this desire, we must first define "lower" and "higher" from a new frame of reference. With our new realization, we can come to the astounding realization that Hashem is equally present in all of the worlds, from the most lofty and spiritual to this most physical.
