lf we understand that Love is the most powerful force in this universe (or any universe or realm) then we understand that any separation we endure from loved ones (or God) is not forever but we go through the temporary separation as part of our learning perhaps?

I can't see the point in God separating humans who love one another.  I don't see this life, or the next, as some sort of testing or preparation ground for another existence in the future.  Sure we can learn, in this life, to make a better job of loving one another in this life.  But why would there need to be further places after death?  Having tiers of life followed by death and further life with all the grief and pain that death causes in between, seems like the design of a torturer rather than a God of Love.
