If there are multi-universes operating at the same time of multi-possibilities, then how will God the Creator interact with each one of us? Indeed a very headache task for God! Karma Law will have to track each one of us in different universe to exact its laws!!! Don't ever think of reincarnation when this concept of multi-universes can adversely affect one's merits (gain or even lose according to one's conduct in different universe) at each reincarnation. Will death be also a multi-possibility? How about past life of multi-possibility when in actual fact regression on past lives is a linear time process than hit & run pundit of chances!
