The basic tenet of faith of the Torah is that God made the world from nothing. Not from Himself.馃槉
I have gone into this a few years ago. But what I wanted to add is that the religious accept pantheism and that besides being not what the Torah holds-it is also hard to see why a good and wise God would reincarnate Himself in a world of infinite torture. We might look at the surface of the sea as calm and benevolent. But underneath the surface everything is waging total war to the death against every other creature. It is a realm the insane torture of chemical warfare. God who by the basic understanding of that word is someone infinitely kind and wise would find no better better way to spend his time than be incarnated in creatures that torture others? And all the more so that vicious of all creatures mankind?
While on the other hand I can see that a wise and kind God would create the world with some deep purpose in mind. But that He should be spending his time torturing all creatures is absurd and contradictory to Torah as you can see in any and all Rishonim who wrote about the faith of the Torah.
{Where did the rishonim write about this? you might ask. Mainly in the books of Musar and world view issues like the Guide. Besides that, the Ari brings at the beginning of the Eitz Chaim that God made the world from nothing --not from Himself. So there is in fact no argument on this point.]
