I came up with this diagram to better explain my thoughts. Starting at the bottom of the diagram then going to the top, this is how I see our lives.
I put rebirth at the top, because I believe home will not exist untill humanity settles on a eternaly co-existant lifestyle. I believe we all have a "home" and it needs us all there to be complete. So basicly we keep building on our path untill one day we make that final step into our home. The top and bottom dot are one in the same, untill its step isnt needed and all thats left is home.
I have dots for the steps that are the same for everyone, and sideways lines for the steps that have multiple options for completion. The time between steps is relative to the person, we all move at different speeds.
