11 levels? Seems rather arbitrary... why not 151? And this seems quite a niche belief set. Is there a particular sect or subset of a religion that teaches these things you write about? So what, do you propose, is the "purpose of the universe?" To get us all through this multi-level "Believer's School?" And to a "graduation" that ends in ascension to heaven? And what purpose does any of that serve? Why expend all of the energy of creating a soul, planting it into a human being, hopping the soul to one and the next "levels" and then promoting the soul to heaven? What is the ultimate goal? God just does all this because He likes it? It makes Him happy? Do we have a purpose in heaven after we make it there? Why does God or heaven need souls?
Why eleven levels? Because it's eleven. You might want to research String Theory if you have more questions about it.
Is there a particular religion that teaches the things I wrote about? You must be very new. If you look at the upper right corner of a person's post it says what religion they follow.
What do I propose is the purpose of the universe? So that God can have full and varied free will personality experiences that He could not have if He still knew who He was.
What purpose does it serve to have the universal school system? God wanted to become more, this is how He chose to do it.
Why expend all of the energy creating a soul? The energy was not expended, it already existed. The soul is a fragment of God that connects with a new mind to gain experience. The soul is not in your body, it connects with your brain. The soul does not "hop" to different levels, it stays in heaven, like watching a movie.
What is the ultimate goal? You ascend to heaven then you plan, supervise, and use God to create your own universe so that God can continue to become more.
God does all this because He likes it? To some degree that is correct but there is some necessity in it as well, at times it may help to think of God as a computer that only does what it has to do.
Why does God need souls? Soul fragments are experiential beings that need to access sentient beings so they can gain experience in order to develop. Think of an infant who needs to be around other humans in order to learn a language, writing, and acceptable social skills.
