(Closely related to this post, but I think it is still a bit different)
Panentheism: A doctrine that the universe subsists within Gcd, but that Gcd nevertheless transcends or has some existence separate from the universe.
Panentheism (aka Monistic Monotheism) plays quite a prevalent role in the philosophy of Chabad (and chassidus in general?), as well as apparently the Nefesh HaChaim (3:3).
Is there anywhere in the body of Rabbinic Judaism, including of course the Geonim, Rambam, and later authorities, that deem such a belief to be forbidden?
Specifically, does the doctrine of panentheism as explained by the sources above, transgress the Rambam's thirteen principles?, specifically (from the third principle) אינו גוף ולא כוח בגוף?
