please elaborate. that it isn't saying the oversimplification is granted. detailed specifics of what it is saying i'd love to hear
Not sure what detailed specifics you're looking for, when it's right there in front of everyone's eyes to see. The "chidush" is that he is drawing the physical conclusion from a metaphysical (I'm not sure if that's the right term, but I didn't want to use ruchnius, as I'm not sure that's the right term either, maybe
@Freddie can help) concept. In the physical world, a circle has no beginning or end, and a sphere has no top or bottom, as all sides are the same. If I understand correctly, the Alter Rebbe is saying that the reason the laws of physics are such in regards to spheres, is because they draw their physical existence from the metaphysical concept of
Igulim which have no top or bottom (i.e. there's no higher or lower level within an
igul).
