Question: In what way does the reality of the world of Assiya differ from the reality of the world of Beria? Does time flow differently there? Is the density of matter different there? Or is there a different quantity of dimensions?
Answer: No! Forget about all the definitions that you have since none of them exist in the spiritual world, not density of matter, not time, not distance, and not motion from one place to another.
The only difference between the worlds is that in each of the worlds or in each level of the worlds there is a certain force of bestowal. This is the only way the worlds and the levels differ from each other.
