I like the thought that when we die we are elevated to a higher state of consciousness and will be provided all the answers to life's big questions.  But perhaps at the moment of our death, consciousness as we know it ceases to exist and we are simply absorbed back into the impersonal universe.  Personally, I would prefer the former, but both options sound plausible to me.  An impersonal universe would have no inclination (or perhaps even ability) to reveal the truth on this matter.  But perhaps not knowing is a purposeful and essential stage in the process of enlightenment.  If I'm learning something by all this I can't tell.
