What one does in this universe could affect the results they encounter in the other universe. If in one universe you are a hero suffering in the other you might be a villain conquering and this all could occur at the same time. This could lead to one universe believing you are being treated cruelly while the other believing you treat others with such cruelty. Therefore our actions here might affect what occurs not just in the steps around us but one in a whole different dimension. Of course, it might not be as simple as this theory as many other universes could be occurring at the same time causing this mathematical formula to be held by a divine power way behind our comprehension. If so why do bad things happen to do good bad maybe answered after all?
FOOTNOTE- This is behind reincarnation as these universes could be occurring ssimultaneously.
