In the sefer Toras Habayis (written by the Chofetz Chayim) in chapter 4 the paragraph that starts with ha'nimshal muvan me'elav, he writes the hierarchy of the olamos (worlds) like this: Briyah, Yetzirah, Galgalim, Asiyah. He then says from Asiyah to the Aretz. What/Whose system is he using?
I'm only familiar with the way the Nefesh HaChaim lays it out: Atzilus, Briyah (Kisei Kevodo), Yetzira (Chayos), Asiyah (Ofanim).
Additionaly (this is not my main question), why does he say "from Asiyah to the aretz"? I thought Asiyah is the physical world?
